Concrete is a mix of several different materials: water, fine aggregates (or sand), coarse aggregates (or gravel), chemical additives, and, most importantly, cement. Cement is what binds all of these ingredients together to give concrete its durability and distinctive, grey appearance. Cement production, however, also generates most of …
