characteristics of mining sand in concrete

Experimental Study on High Strength Concrete using

Generally the river sand is used as a fine aggregate on concrete and is obtained by mining the sand from river bed. Increased sand mining not only affects the aquifer of the river bed but also causes environmental problems. In recent days demand for river sand is increasing due to its lesser availability.
