Ground Granulated Blast Furnace Slag (GGBS) is a by-product from the blast-furnaces used to make iron. It is a glossy silicate of Calcium, Iron, Alumina and other base materials produced in Blast Furnace. Lime stone is poured in B.F. with Iron-ore because it gives exothermic reaction which generates heat. Lime stone itself melts and combines with Silicate. Hence it is a mixture of Calcium Silicate, Iron and Aluminium Silicate and Cement is also a mixture Mono, Di, Tri and Tetra Silicates with Iron & Aluminium Silicates. Therefore GGBS is a meterial with Cementitious nature.We can supply GGBS of different quality and properties engineered to specific customer’s demands at very competitive rates, in bulk carriers, or packed in 50 kg HDPE bags. Applications of GGBS :GGBS is used to make durable concrete structures in combination with ordinary portland cement and/or other pozzolanic materials. GGBS has been widely used for its superiority in concrete durability, extending the lifespan of buildings from fifty years to a hundred years. Two major uses of GGBS are in the production of quality-improved slag cement with GGBS content ranging typically from 30 to 70%; and in the production of ready-mixed concrete. Advantages of GGBS :Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cementitious material, but also continues to gain strength over a longer period in production conditions. This results in lower heat of hydration and lower temperature rises, and makes avoiding cold joints easier.Use of GGBS significantly reduces the risk of damages caused by alkali–silica reaction (ASR), provides higher resistance to chloride ingress - reducing the risk of reinforcement corrosion - and provides higher resistance to attacks by sulfate and other chemicals.
