The aggregate is generally coarse gravel or crushed rocks such as limestone or granite, along with a fine aggregate such as sand. The cement, commonly Portland cement, and other cementitious materials such as fly ash and slag cement, serve as a binder for the aggregate.
Mainly natural and cheapest resource of sand is river and nowadays it reducing day by day. It is crushed stones into cubical shape particles to use for ready mix concrete and base material for road work. Plaster sand is of cubical shape and it is used for construction work, concreting, plastering etc.
