Leading Manufacturers of GGBS (Granulated Blast Furnace Slag ).We IVS industries is a partnership firm ,manufacturing good quality of GGBS (Granulated blast Furnace Slag ) out of raw material .IVS industries has a capacity to produce 200 to 250 mts. per day GGBS under the brand name “ Magic Power ”at their plant situated at A-22 , MIDC , Butibori , Nagpur. GGBS (also known as GGBS or GGBFS) is manufactured from blast furnace slag, a by-product from the manufacture of iron. GGBS is obtained by quenching molten iron blast furnace slag immediately in water or stream, to produce a glassy granular product that is then dried and ground into a fine powder. It is an excellent binder to produce high performance cement and concrete. GGBS, in contrast, is a hydraulic material, which means that it will set and harden due to a chemical reaction with water. After hardening, it will retain some strength development and remain stable even under water. Concrete containing GGBS cement has a higher ultimate strength than concrete that uses 100% Portland cement. The difference in the permitted replacement ratio: The permitted replacement ratio of PFA in OPC is 20-40%, but it’s usually no more than 35% in concrete. On the other hand, the permitted replacement ratio of GGBS in OPC or concrete is 20-70%.
