Is there a business case for crushed sand? - Metso Outotec
Jan 12, 2020 The Concrete has been traditionally made with use of Natural / River sand as fine aggregate. As sand contributes to around 25 to 35% of total concrete along with coarse aggregates, cement & water, the properties of the fine aggregates would be one of the major influencing factor in determining the fresh & hardened Concrete properties and performance with respect to workability, …The Civil engineers, Architects, Builders, and Contractors agree that the river sand, which is available today, is deficient in many respect. It does content very high silt fine particles (as in case of Filter sand). Presence of other impurities such as coal, bones, shells, mica and silt etc makes it inferior for the use in cement concrete.
