|
Concrete is a composite material composed of fine and coarse granular aggregate (which acts as a filler material) embedded in a hard matrix of cement (which acts as binder) that fills the space among the aggregate particles and glue them together. The main constituents being cement, fine aggregate (river sand), coarse aggregate and water. The increase in cement production and its usage and also its impact on the environment is addressed widely throughout the world in recent years, which gave light to researches to use alternative materials to cement such as fly ash, silica fume, ggbs etc. But now the focus is also on the increase in demand of the other constituent materials of concrete such as fine and coarse aggregate. Following the same lines of research and in a verge to find a new alternative material for river sand which is available in sufficient quantity in India and other countries also as a potential to be use as sand in concrete as resulted in using LD slag ( granulated blast furnace slag) as a fine aggregate in concrete. |
