What Is Crushed Sand? - Is It Good ? [Civil Planets]

The strength of the concrete is increasing while using crushed sand instead of river sand. Even though now P sand (Plastering Sand) is available especially for plastering work. The P sand also a type of crushed sand and the particle size lesser than the normal M sand, which is suitable for plastering work.IS 383 (1970): Specification for Coarse and Fine,,25/09/1970· 1.1 This standard covers the requirements for aggregates, crushed or uncrushed, derived from natural sources, such as river terraces and river- beds, glacial deposits, rocks, boulders and gravels, for use in the Production of concrete for normal structural purposes including mass concrete works. 4Behaviour of Concrete on Replacement of Sand with,Mahendrana et al studied on feasibility of the usage of Quarry Rock Dust as hundred percent substitutes for Natural Sand in concrete.
