Mechanical and Durability Properties of Concrete

River sand is one of the main ingredients used as a fine aggregate in concrete production. A rising demand for construction material has led to the overexploitation of river sand, and this overexploitation has led to harmful consequences like increase in river bed depth, lowering of the water table, and intrusion of salinity into the river.
