 Applications & Benefits:

 

It is a type of eco-friendly green building material, has been recognized as one of the best Secondary Cementitious Material for building high durable concrete structure in the world today.

 

1 Durability

GGBS has now effectively replaced sulfate-resisting Portland cement (SRPC) on the market for sulfate resistance because of its superior performance and greatly reduced cost compared to SRPC. Most projects in Dublin's Docklands, including Spencer Dock, are using GGBS in subsurface concrete for sulfate resistance.

 

2 Appearance

In contrast to the stony grey of concrete made with Portland cement, the near-white color of GGBS cement permits architects to achieve a lighter colour for exposed fair-faced concrete finishes, at no extra cost. GGBS cement also produces a smoother, more defect free surface, due to the fineness of the GGBS particles. Dirt does not adhere to GGBS concrete as easily as concrete made with Portland cement, reducing maintenance costs. GGBS cement prevents the occurrence of efflorescence, the staining of concrete surfaces by calcium carbonate deposits.

 

3 Strength

Concrete containing GGBS cement has a higher ultimate strength than concrete made with Portland cement. It has a higher proportion of the strength-enhancing calcium silicate hydrates (CSH) than concrete made with Portland cement only, and a reduced content of free lime, which does not contribute to concrete strength. Concrete made with GGBS continues to gain strength over time, and has been shown to double its 28-day strength over periods of 10 to 12 years.

 

4 Sustainability

Since GGBS is a by-product of steel manufacturing process, its use in concrete is recognized by LEED etc. as improving the sustainability of the project and will therefore add points towards LEED certification. In this respect, GGBS can also be used for superstructure in addition to the cases where the concrete is in contact with chlorides and sulfates. This is provided that the slower setting time for casting of the superstructure is justified.

Turkey’s cement industry: Onwards and upwards

The Republic of Turkey, which is divided into 81 provinces that are grouped in seven regions, spans 783,562km2 in western Asia and southeast Europe. Turkey's estimated 2014 population of 82 million is ruled by a president and a prime minister in a democratic constitutional republic. The EU-Turkey Customs Union has led to extensive liberalisation of tariff rates, making Turkey a major trader with European countries like Germany and the UK. Turkey also started full EU membership negotiations with the European Union (EU) in 2005. Turkey's cement industry is one of the largest in the world. Here, Global Cement provides an industry overview, including Turkey's top producers, recent cement sector events and its outlook.
Economy

Turkey, which has an emerging market economy as defined by the International Monetary Fund (IMF), had a GDP (purchasing power parity - PPP) that rose by 4% year-on-year to US$1.167tn in 2013, up from US$1.124tn in 2012 (Figure 1).1 Its GDP/capita grew to US$15,300 from US$15,000 in 2012. GDP was contributed to by the service sector (63.8%), industry (27.3%) and agriculture (8.9%). Industrial production grew by 3.8% in 2013. Inflation (consumer prices index - CPI) fell to 7.6% in 2013 from 8.9% in 2012.

Turkey's labour force was 27.1 million in 2013, although some 1.2 million of those workers were employed abroad. Unemployment rose to 9.3% from 9.2% in 2012, while youth unemployment (aged 15 - 24) rosto 17.5%. The population grew by 1.12% to an estimated 81,619,392 in 2014, 16.9% of which lived below the poverty line.

Turkey is a net importer of goods. During 2013, some US$243bn of goods, mainly machinery, chemicals, fuels and equipment was imported, while US$168bn of goods that primarily comprised textiles, foods and garments were exported. Although Turkey has a strong industry and production base, it relies on imported oil and gas for 97% of its energy needs.1 Several gas pipelines projects to transport central Asian gas to Europe through Turkey are ongoing, which should ultimately increase supply confidence.

Cement industry

Turkey has 50 active integrated cement plants and 84.6Mt/yr of production capacity (Figure 2), according to the Global Cement Directory 2015 and Global Cement research. A further three integrated plants are under construction, one grinding plant is having its first clinker line installed to become an integrated cement plant and another plant is being relocated in Afyon. Turkey also has 17 active grinding plants (excluding the soon-to-be integrated cement plant) and >8.56Mt/yr of grinding capacity. The production capacities of some of the grinding plants is unavailable. The Turkish Cement Manufacturers' Association (TCMA) claims that Turkey has significantly higher cement and clinker production capacities than Global Cement can verify (Table 1).2

The TCMA reported that in the first 11 months of 2014, cement production fell by 2.41% year-on-year to 65.2Mt, while clinker production grew by 2.92% to 56.5Mt.2 Given that 4.56Mt of cement was produced in December 2013, Turkey's cement production for the entirety of 2014 is unlikely to have exceeded 70Mt. This is significantly less than the United States Geological Survey's (USGS) estimated 75Mt of cement production in 2014.3 Turkey lost out on being the fourth-largest cement producer in 2014 and now shares that position with Iran, which, according to the USGS, also produced 75Mt of cement in 2014. Turkey and Iran follow China (2.5Bnt), India (280Mt) and the US (83.3Mt). Brazil, which produced 72Mt of cement in 2014, is closing in on Turkey's production.

In the entirety of 2013, the latest year that full data is available, the capacity utilisation rate of the TCMA's member companies was 69% for cement and 92% for clinker (Table 1). Cement capacity utilisation was lowest in East Anatolia (57%) and highest in Marmara (75%). Clinker capacity utilisation was lowest in Central Anatolia (85%) and highest in Marmara (99%). Cement is primarily produced in the west of the country, with capacities of >15Mt/yr in the Marmara and Mediterranean regions (Figure 2). In the first 11 months of 2014, the TCMA reported that cement production grew by 3.17% in the Black Sea region, but fell in all other regions. Clinker production fell by 1.21% in Marmara, by 1.44% in Central Anatolia, by 0.77% in East Anatolia and by 0.04% in Southeast Anatolia. Clinker production rose in the remaining regions.

Domestic cement sales were 60.9Mt in 2013. They were highest in Marmara at 14.1Mt and lowest in Aegean at 5.19Mt. CEM II was the most-common type of cement bought by the domestic market in 2013, when sales volumes hit 20.1Mt (Table 2). Some 5.92Mt of CEM IV and 1.2Mt of CEM III was sold to domestic buyers. In contrast, CEM I was the most popular type of cement for export; in 2013, some 4.74Mt was sold. CEM II, of which 3.99Mt was sold, also proved popular. Turkey is also one of the world's most significant producers of white cement. It is produced by Çimsa Çimento in Mersin (1.10Mt/yr) and by Adana Çimento (Oyak Group) in Adana (0.35Mt/yr). Both plants are in the Mediterranean region.

Readymix concrete producers are Turkish cement producers' largest single customer type. In 2013, they bought 32.3Mt of cement, some 52.9% of the country's production. Distributors are Turkey's second-largest cement buyer. They bought 20.5Mt of cement in 2013, 33.7% of the country's total. Contractors bought 2.94Mt (4.83%), construction firms bought 2.41Mt (3.95%) and precast concrete producers bought 1.97Mt (3.24%). In contrast with typical developing countries, Turkey's domestic cement sales were primarily in bulk as opposed to bagged.

Cement exports fell by 4.08% year-on-year to 9.63Mt in 2013. The majority of exports was from the Mediterranean (4.87Mt, 50.6%), Marmara (1.88Mt, 19.5%) and Southeast Anatolia (1.33Mt, 13.8%) regions. Cement was exported to 86 countries, primarily to Libya (2.89Mt), Iraq (1.62Mt), Russia (1.08Mt), Israel (631,256t) and Syria (566,140t). Clinker exports fell by 22.2% year-on-year to 2.18Mt in 2013. Clinker was exported to 27 countries, mainly Israel (207,363t), Brazil (199,110t), Togo (173,200t), Ghana (170,145t) and Romania (167,250t).

Exports were dispatched by sling (3.29Mt, 34.2%), by bag (2.75Mt, 28.5%), in bulk (2.46Mt, 25.6%) and by bigbag (1.13Mt, 11.7%). In contrast to domestic sales, there was a large regional variation in export methods. Central and East Anatolia both used bags for 100% of their exports, while Marmara used 0% of bags and Aegean exported 0.2% of its cement by bag. Aegean was the only region to export primarily by bulk (61.6%), while Marmara used a combination of bulk, sling and bigbag. The Mediterranean region, which exports the largest quantity of cement, used mainly sling (42.3%) and bag (35.7%).

Cement producers

The majority of cement producers in Turkey are Turkish companies. Akçansa Çimento, Oyak Group, Çimsa Çimento, Limak Batı Çimento, Aşkale Çimento and Limak Çimento are the country's major Turkish cement producers. There are also many companies that have one or two cement plants each. Multinational producers like Votorantim Çimento, Lafarge, Cementir Holding and Vicat are also active in Turkey's cement market.

Oyak Group is Turkey's largest cement producer by installed integrated cement production capacity (Table 3). In 2015 it has 15.3Mt/yr of production capacity from six plants. It also has two active grinding plants. A third grinding plant run by its Bolu Çimento subsidiary in Caydurt, Bolu is having a clinker line installed to convert it to an integrated plant. Oyak's net sales grew by 14% year-on-year to US$552m in 2014.4 Its operational income grew by 31% to US$172m, while earnings before interest, taxes, depreciation and amortisation (EBITDA) rose by 26% to US$199m. Net profit grew by 69% year-on-year to US$163m. Mardin Çimento in Southeast Anatolia was the only one of Oyak's subsidiaries to have a poor year. Its net sales were flat, while operating income and EBITDA were both down. However, the plant managed to increase its net profit by 15% year-on-year by 'utilising the struggling Middle Eastern markets.' During 2014, Oyak's Bolu Çimento started to produce and sell slag cements, which according to Oyak, helped it to increase its sales in the 'very fragmented and highly competitive Mediterranean market.'

Akçansa Çimento, which has five integrated cement plants and 8.63Mt/yr of cement production capacity, is Turkey's second-largest cement producer. It also has one grinding plant in Iskenderun with 10 lines. Established in 1996, Akçansa is a joint venture between Sabancı Holding (39.7%) and HeidelbergCement (39.7%). The remaining 20.6% of shares are owned by public shareholders. In 2014 Akçansa's cement division reported US$401m of sales, up by 19% year-on-year, an operating income of US$125m, up by 58% year-on-year and an operational profit of US$121m, up by 59% on 2013. As for Turkey's other large producers, Akçansa has made significant recent investments in alternative fuels. Its thermal substitution rate was 6.67% in 2013, when it had alternative fuels firing capabilities at its Büyükçekmece, Çanakkaleand Ladik plants.

Çimsa Çimento is the third-largest cement producer in Turkey. It has four active integrated cement plants that have 7.57Mt/yr of production capacity; its fifth integrated plant, Afyon Çimento, is currently being upgraded from 0.55Mt/yr of cement production capacity and relocated between two villages in Halimoru. Çimsa also has one 530,000t/yr capacity grinding plant in Ankara. Çimsa produces white cement and calcium aluminate cement as well as CEM I, CEM II, CEM III and CEM IV. In the first quarter of 2014, which ended on 31 March 2014, Çimsa produced 1.26Mt of cement, including 218,375t of white cement, 8421t of ISIDAÇ-40 (a calcium aluminate cement) and 1081t of sulphate-resistant (SRC) cement. In the entirety of 2014, Çimsa reported US$1.094bn of sales and an operating profit of US$93.6m.

Nuh Çimento is the fourth-largest producer in Turkey, with just one integrated cement plant that has 5.7Mt/yr of production capacity. The company launched cement production in 1969 and has continually updated and expanded the plant in the years since. Most recently, in 2012, it commissioned a refuse-derived fuel (RDF) feeding system and an 18MW waste heat recovery (WHR) system. The capacity of its sea water desalination plant was also increased to 600m3/hr. In addition to CEM I, CEM II and CEM IV, Nuh Çimento also produces oil well cement Class G type HSR (high sulphate-resistant).

Limak Batı Çimento is Turkey's fifth-largest cement producer. It was established in 1976 and now has five cement plants and 5.41Mt/yr of integrated cement production capacity. Limak Batı Çimento also has one 1.3Mt/yr grinding plant in Istanbul.

Plant news

In recent months many announcements have been made of upgrades and expansions, and even one relocation, within Turkey's cement sector.

In December 2013, Oyak's Bolu Çimento ordered three vertical roller mills from Gebr Pfeiffer for a new production line at its grinding plant in Kazan, Ankara. The mill will expand the existing grinding plant into an integrated cement plant. One 320t/hr capacity MPS 4500 B mill with 3150kW of drive power for raw material grinding to a fineness of 12% residue on the 0.090mm screen was ordered. Also included was an MPS 225 BK vertical roller mill, which will grind 20t/hr of petcoke to a fineness of 3% residue on the 0.09mm screen and 35t/hr of lignite to the same specifications. The third mill was a 130t/hr MPS 4500 BC mill with 3300kW of drive power, which will grind CEM I to a specific surface of 3900cm²/g Blaine. In April 2014 KHD was asked to supply a 3500t/day clinker line to the same plant, to be commissioned in the spring of 2015. The order included engineering, equipment supply and advisory services for installation and commissioning.

In January 2014 the International Finance Corporation (IFC) agreed to give Çimko Çimento a US$40m loan from its own account and a US$25m syndicated loan from BNP Paribas Fortis, mobilised by the IFC. The investments will enable Çimko to reduce its greenhouse gas emissions, supply more cement to the domestic market and export more cement to Middle East and North Africa. Çimko is a joint venture between Turkey's Sanko Group and Italy's Cementerie Aldo Barbetti.

In April 2014 Göltaş Göller Bolgesi Çimento contracted China's Catic Beijing Co to set up a US$14.7m WHR system at its cement plant in Isparta. The system is expected to be installed in 2016 and should reduce the plant's electricity costs by 25%. This followed a July 2013 contract with Loesche for the supply of a 230t/hr type LM 56.3+3 vertical roller mill. Also in April 2014, Bursa Çimento Fabrikası started operation of its 7.5MW WHR system at its cement plant in Bursa. The US$15m system can generate 50MkWh of electricity from waste heat and avoid 28,000t/yr of CO2 emissions.

In June 2014 Gebr Pfeiffer received an order from Oyak's Bolu Çimento for an 85t/hr MPS 4500 BC mill to grind granulated blast furnace slag (GBFS) at its Bolu plant. The GBFS will be ground to a product fineness of 4500 - 4750cm²/g. Gebr Pfeiffer's scope includes the core components of the mill and classifier as well as the mill gearbox. The delivery of the mill was scheduled for early 2015. June 2014 saw Gebr Pfeiffer receive another Turkish order, from plant builder Bilim Makina for four mills destined for Çimentaş Elazığ's (part of Cementir) cement plant in Elazığ. It included a 35t/hr MPS 250 BK roller mill with 500kW of drive power for grinding coal into petcoke and two safety shut-off dampers. The material will be ground to a fineness of 3.5% R90µm. Also included was a 470t/hr MPS 5000 B mill, which has 3800kW of drive power and grinds to a fineness of 12% R90µm. Two 200t/hr MPS 5000 BC vertical roller mills with 4400kW of drive power each, were ordered for grinding cement to Blaine 3400cm2/g. All of the mills were scheduled to be delivered to Çimentaş Elazığ in the spring of 2015.

Simultaneously, Austria's A TEC Production & Services GmbH was redesigning the four cyclone stages, riser ducts and related equipment of the preheater tower at the same plant. The project aims to reduce the total preheater pressure drop by 25% and to increase production capacity by at least 8% on a sustainable basis. The first stage was completed in May 2014, while the second, third and fourth stages were started in 2014 and are due for completion in 2015. Phase one resulted in a sustainable production increase of 8% and a pressure drop reduction at the fan inlet by 19%. It is expected that the pressure drop before the fan will be reduced beyond the target 25% after completion of phase two, which will allow higher production at less specific power consumption on the fan than initially targeted.

In August 2014 Limak Çimento announced that it would partner with Ivory Coast-based Akfirbat to set up a US$50m grinding and packaging plant in the Ivory Coast's capital Abidjan. The two companies held a signing ceremony in Ankara for the establishment of a joint venture company called Limak Afrika SA. The plant will have 1Mt/yr of grinding capacity and 1Mm3/yr of concrete production capacity. Operations are expected to begin in October 2015. The plant's production will be sold in the Ivory Coast and other African countries.

In November 2014 Afyon Çimento, part of Çimsa, allocated US$140m to relocate and upgrade its 550,000t/yr capacity cement plant from Afyonkarahisar City, Afyon, to Halimoru Village in Afyon.

Acquisitions

In March 2014 Cementir announced plans to close a deal within 12 months that could enhance its position in the white cement industry. Company CEO Francesco Caltagirone said that Cementir waslooking at potential acquisitions in the US, sub-Saharan Africa and the Far East. Cementir also planned to boost its waste management operations in Europe, beyond the markets in Turkey and northern England where it is currently focused. No additional details have since been forthcoming.

In April 2014 Oyak announced that it was looking into acquisition opportunities in the cement sector, mainly in Europe (specifically the UK) and Africa, according to its cement group chairman Celalettin Caglar. Oyak added that it was interested in acquisition opportunities, especially in Romania, Hungary and Serbia, that could arise from the LafargeHolcim merger and prepared US$2bn in cash ready for such acquisitions. In September 2014 Sabancı Holding also announced plans to bid for LafargeHolcim assets. "Sabancı is interested in these sales. Preparations are being made to make a bid in December 2014," said a Sabancı spokesperson. Although CRH has recently entered into a US$6.89bn agreement to acquire a large portion of the LafargeHolcim assets in Europe, Canada, Brazil and the Philippines, other assets may still be available for purchase by Turkey's producers.

In August 2014 Ireland's CRH and Eren Holding hired JP Morgan Chase & Co to help sell their 50/50 Turkish cement joint venture, Denizli Çimento. Sabancı Holding, Limak Çimento and Oyak all announced interested in the plant. Denizli produces about 31% of western Turkey's total clinker output. On 10 November 2014, Oyak completed the purchase of Denizli Çimento for US$400 - 450m.

In January 2015 Sançim Cimento was acquired by Aşkale Çimento, a joint venture of Sönmez Holding (43%), Aunde Teknik (38%), E.N.A. Tekstil (10%) and Umut Insaat (9%). The acquisition followed the aborted purchase of Sançim by Çimsa for US$194m.

Outlook

According to the IMF, Turkey's GDP will grow by 3% in 2015, following 4% growth in 2013 and 3.3% in 2014. Growth is set to remain stronger than emerging and developing European countries, but weaker than the world average. The IMF has predicted that growth will shift towards private consumption and investment due to the delayed effect of recent monetary easing predicted for 2015. Al-Monitor reported that although 2014 saw Turkey's economy fall short of most of its targets, 2015 would be positive for Turkey thanks to falling oil and natural gas prices.5 These, it said, should boost economic growth and decrease the deficit and inflation.

A large number of projects are expected to continue to drive Turkey's construction and cement industries in the near future. These include highways, a road tunnel under the Bosphorus Strait, stadia constructions and new metro lines. In addition, Turkey plans to construct the world's largest airport in Istanbul for around US$5.6bn.6 The airport will ultimately have six runways and be able to process 150m/yr passengers. The first stage is scheduled to be completed in 2017 and is expected to require a significant quantity of construction materials, including cement.

Turkey's cement producers are well-prepared for growing cement demand amid a strong construction sector. Although no new plants have been announced so far in 2014 - 2015, Turkish producers appear to prefer to expand existing plants to increase their production capacity. Indeed, nine integrated cement plants are currently undergoing upgrade or expansion projects that will see >11Mt/yr of additional integrated capacity added within the next few years (Figure 2). Oyak has forecast that, in 2015, domestic cement demand will grow by 5% year-on-year thanks to the general elections, strong infrastructure investments and rising demand for residential construction and urban regeneration projects.

An increasing focus on environmentally-friendly cement production can be expected, judging from the TCMA's participation in Turkey's Waste Management Symposium on 29 January 2015.7 The key topics of the TCMA's 13th International Technical Seminar and Exhibition on 7 - 10 October 2015 highlight the same trend; low-carbon technologies, industrial symbiosis, use of wastes and innovation and new technologies will all be covered.8 Waste heat recovery and alternative firing systems are likely to become more frequent orders from cement producers.

In summary, Turkey's cement sector is likely to grow at a steady pace for the foreseeable future thanks to healthy demand by the domestic and export markets. Low oil and gas prices, which many now believe will endure much longer than initially expected, will provide a boost to Turkish cement production costs and increase profitability.

Низкоуглеродистой Цемента (ggbs) - Buy Product on Alibaba.com

Описание:

Выбросы от обычного портландцемента и низкоуглеродистой цемента (ggbs) производства

CO2 признана одной из основных причин изменения климата. В Ирландии, обыкновенный портландцемент производство второй крупнейших промышленных источник CO2 и выбросов NOx, После генерации электроэнергии из ископаемого топлива. Кроме того, о одну пятую всех выбросов диоксинов от промышленности в Ирландии возникают из цемента производства. Однако производство ggbs из шлак доменный, промышленных побочный продукт, создает очень низкий CO2 выбросов, и нулевым уровнем выбросов других загрязнителей.

Производство и использование ggbsГранулированный доменный шлак (ggbs) изготавливается из доменный шлак, По-продукт от принятия гладить. Цементные свойства шлак доменный были обнаружены в конце 19th века и он был широко используется в производство цемента на более 100 лет. В Великобритании, ggbs поставляется как отдельный компонент для бетона и добавляется в бетоносмеситель. Как правило, он заменяет между 20 и 80 процентов нормального портландцемента.

Производство Утюг доменный шлакДоменных печей используется, чтобы сделать гладить работать при температурах до 2000 °C и подается с тщательно управляемый смесь железной руды, Кокс и известняка. Железной руды превращается в железа, которое раковины к нижней части печи. Остальные материалы образуют шлака, что плавает на верхней части утюга. Расплавленного железа и шлака являются обращается с через определенные промежутки времени через коснувшись отверстия в основании печи. Как шлака обращается с, Его химии контролируется как проверка на производительность печи. Это гарантирует, что доменный шлак очень последовательны в химический состав.

После перехвата из печи и отделен от железа, шлака охлаждается. Скорости охлаждения расплавленного шлака определяет его физические характеристики. Если материал слева постепенно воздух-холодный, Это не использовать как цементный материала и используется как агрегат. Где доменный шлак будет использоваться для изготовления ggbs, Это должно быть быстро закаленных в воде. Этот процесс известен как грануляции потому что это производит стекловидный гранулы, похожа на грубой песок. Эти имеют отличные вяжущими свойствами.

Экономические выгодыИспользование цемента замены с более экономичными трудности предлагает возможности для значительное сокращение использования энергии и углекислого газа выбросов. Наиболее эффективной альтернативой портландцемент является гранулированный доменный шлак (ggbs), который обычно Заменяет 50 процентов портландцемента в бетонной смеси. Больше пропорции до 70 или даже 80 процентов, может быть использован с преимущество в подходит ситуациях.

Преимущества использования ggbs в бетоне:1 экономит энергию2 снижает выбросы углекислого газа3 сохраняет природные ресурсы.

Ggbs и конкретных свойствНа свой собственный, гранулированный доменный шлак (ggbs) затвердевает очень медленно и, для использования в бетоне, она должна быть активирована путем объединения его с портландцемента. Типичное сочетание 50 процентов ggbs с 50 процентов портландцемент, Но проценты ggbs где угодно между 20 и 80 процентов обычно используются. Чем больше процент ggbs, тем больше будет эффект на конкретных свойств.

Установка разНастройки времени бетона зависит от многих факторов, в частности температуры и водоцементное отношение. С ggbs, установка времени будет слегка расширенные, возможно, примерно на 30 минут. Эффект будет более выраженным при высоком уровне ggbs и/или низких температур. Расширенный время установки выгодно в том, что бетона останется работоспособным дольше и будет меньше риск холодной суставов. Это особенно полезно в теплую погоду.

Воды спросаРазличия в реологических поведение между ggbs и портландцемента может включить Небольшое сокращение содержание воды для достижения Эквивалент консистенции класса.

КонсистенцияВ то время как бетонов содержащий ggbs есть аналогичные, или немного улучшилась консистенции эквивалентную портландцемент бетонов, Свежий бетона содержащие ggbs имеет тенденцию требуют меньше энергии для движения. Это делает его легче место и компактный, особенно когда накачки или с помощью механических вибраций. Кроме того, он сохранит ее работоспособность дольше.

Раннего возраста повышение температурыРеакции участвующих в настройки и усиления из бетона генерировать значительные тепла и может произвести большой температура поднимается, Особенно в толстой-раздел сыпется. Это может привести к термическому растрескиванию. Замена портландцемент с ggbs уменьшает повышение температуры и помогает избежать раннего возраста тепловой трещин. Существует много факторов, которые определить скорость тепла развития и максимальная температура на талии. Они включают процент ggbs, общая цементные содержание, размеры структуры, Тип опалубки и окружающей среды погодных условиях. Чем больше процент ggbs, ниже будет скорость, с которой тепло разработаны и меньше Максимальная температура на талии. А также предусмотрена максимальной температуры, время, необходимое для достижения Пик будет продлен. Для массового бетонных конструкций, распространено использовать 70 процентов ggbs для контроля температуры на талии. С тоньше разделы, значительную экономию в трещины управления подкрепление может быть достигнуто даже с более низким уровнем ggbs 50 процентов или меньше.

Набраться сил в ggbs бетонаС тем же содержание цементный материал (общий вес портландцемента плюс ggbs), Подобные 28-день силы, чтобы портландцемент обычно быть достигнуто при использовании до 50 процентов ggbs. При более высокой ggbs проценты цементные содержимого может должны быть увеличена до достижения эквивалент 28-день прочность.Ggbs бетона набирается сил более устойчиво чем эквивалент бетона Сделано с портландцемента. Для того же 28-день прочность, ggbs бетона будет ниже прочность при раннего возраста но его длительной прочности будет больше. Сокращение в начале-сила будет заметен при высокой ggbs уровней и низких температур.При нормальных обстоятельствах, бетонов с до 70 процентов ggbs достигнет достаточную прочность в течение одного дня литья, чтобы разрешить удаление из вертикальной опалубки без механических повреждений. При высокой ggbs проценты, Дополнительный уход должны быть приняты с шлифах налил во время зимних условиях, когда твердения бетона может были затронуты путем холодного воздуха.

ЦветГранулированный доменный шлак Off-White в цвет и существенно легче, чем портландцемента. Этот белее цвет также замечена в бетоне Сделано с ggbs, особенно в дополнение скорости 50 процентов и выше. Более эстетически привлекательный внешний вид ggbs бетон может помочь смягчить визуальное воздействие большой структур, таких как мосты и подпорных стен. Для цветной бетон, пигмент требования часто уменьшается с ggbs и расцветка ярче.

Ggbs и долговечностьБетона содержащие гранулированный доменный шлак (ggbs) является менее проницаемой и химически более стабильным, чем обычный бетон. Это повышает его устойчивость к многих формах вредных атаки, в частности:

1 распаду из-за сульфата атаки2 хлорид связанных коррозии арматуры3 трещин, вызванных щелочно-реакции кремнезема
