One of these materials is the " blast furnace slag ". So, what happens is you reduce the amount of cement; instead of using cement, now we can use less amounts. The equation for example turns to: concrete = % of normal cement + % of blast furnace slag + water + fine aggregate + coarse aggregate + admixtures.

Abstract. Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten …

JSW Portland Slag Cement (PSC) is a blended cement, wherein some portion of OPC is replaced with Ground Granulated blast furnace slag (GGBS), to make the structures more lasting. According to the EPD data, global warming potential of PSC is 325.14 kg CO 2 equivalent. As a result of lower clinker factor due to substitution with slag, the global ...

Concrete Properties. The physical properties of Ground Granulated blast furnace slag (GGBFS) provides advantages to the concrete in fresh state as well as in its hardened state. It is always recommended for a concrete mix design, that would provide us with a denser mass of concrete, i.e. a solid that is free from voids.
