alternative material to natural sand. Some alternatives materials have already been used as a replacement of natural sand such as flyash, quarry dust or limestone and siliceous stone powder, filtered sand, copper slag are used in concrete and mortar mixtures as a partial or full replacement of natural sand (Chandana Sukesh et al 2013)[9].
Soil is often the hardest to predict and most difficult to work with material on a construction project. Unlike steel, aluminum, glass, cement, etc., soil as a construction material tends to be nonhomogeneous (material properties vary widely within a sample). So it pays to understand soils. Why Should I Worry about Organic Soils?
Specific types of sand are used in the manufacture of glass and as a moulding material for metal casting. Other sand is used as an abrasive in sandblasting and to make sandpaper. Sand is a significantly important material for the construction but this important material must be purchased with all care and vigilance. Pit Sand (Coarse sand)
