1.0 INTRODUCTION Concrete is generally composed of aggregates, cement and water. The aggregates are usually coarse and fine aggregates. Cement is used for binding the concrete materials together. Coarse aggregates have particles bigger than 5 mm in diameter while fine aggregates have particles smaller than 5 mm in diameter. Cement is hydrated to form a gel …

River Sand River sand is a worn out particles of stone. River sand contains particles of various types of stones. Hence, each and every particle is not having similar crushing strength. River sand contains impurities like Shells, Coal, Organic Material, Wood, Bones, Silt. These impurities decay in due course of time.
