Replacement of Sand in Concrete for Sustainable Building
River sand is one of the primary materials used in manufacturing concrete. ... Quarry dust can be partially used as an alternative to river sand, as fine aggregate in concrete production. It is basically a by-product of stone crushers produced during the crushing and screening process of coarse aggregates.
