And opposed to reverse sand, crushed sand has a lower slump. There are no aquatic items in it. M Sand has a bulk density of 1.75 gm/cm3. It has a specific gravity of 2.5 to 2.9, depending on the parent rock. While using M Sand in concrete, no bulkage correction is needed during mix design. M Sand can hold up to 10% of its initial moisture.
Before we get into the advantages and disadvantages of manufactured sand, what exactly is manufactured sand? Manufactured sand is sand produced by crushing rocks, quarry stones or larger aggregates pieces into sand-sized particles. Natural sand, on the other hand is the naturally formed sand extracted from river beds. The Manufacturing Process

M sand: River sand: Definition : M sand is produced by crushing large aggregate pieces, rocks, or quarry stones in a quarry or factory: River sand is a type of sand that is naturally available and extracted from riverbanks or riverbeds: Shape: Angular or cubical: Rounded: Texture: Rough: Smooth: Moisture content: It has less or no moisture content
Benefits of using a washed plaster sand versus an unwashed plaster sand: Washed plaster sand has a reduced silt/clay content (<75 μ m), this will prevent shrinkage cracks in the plaster work. Washed plaster sand with a reduced clay content will have a higher strength when compared to unwashed plaster sand.
