Artificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than 4.75 mm. It is processed by mechanical crushing and sieving. In China, the artificial sand was mainly used in the construction of hydropower systems.

Fines Separator for Aggregates, Sand & Minerals In construction industries stone metal (Crushed stone) is main ingredient for cement concrete. In crushing process fine dust below 75 micron is generated . Fine dust is having more surface area hence requires more water. It increases water cement ratio.

Natural aggregates are obtained by mining sand and stone, which are then crushed, washed and sorted. Waste silt is produced at typical aggregate washing plants at between 5 and 80 ton per hour depending on plant size and materials being processed. In general, 10–15% of the raw sand and stone will become waste silt.

In the following table the main differences between Fine and coarse aggregate are given: Fine aggregates are small size filler materials in construction. Coarse aggregates are larger size filler materials in construction. Fine aggregates are the particles that pass through 4.75 mm sieve and retain on 0.075 mm sieve.

Many studies have examined the influence of the partial replacement of fine aggregate in concrete using crusher dusts or small crushed sand samples on concrete properties [8,12,13]. However, little work has been performed on the complete replacement of natural fine aggregate in concrete with crusher dusts.

The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity.

3.Shape of fine aggregates: Irregularly nodular shaped sand is preferable to completely round grained sand. The shape of the aggregate plays a more important role in the coarse aggregate than in the fine aggregate. 4.Specific Gravity: The specific gravity of aggregates is the ratio of the density of water to its density.
