river sand as a fine aggregate in concrete is not possible so we go for a quarry dust as a fine aggregate. Quarry dust are available easily in all places and in concrete it is the best filling material and also achieve more strength than river sand. The setting time of concrete also decreased hence it should be preferred for water log areas.
