Feasibility Of Artificial Sand In Concrete

artificial sand as fine aggregate gives consistently higher strength than the mixes with natural sand. The sharp edges of the particles in artificial sand provide better bond with cement than the rounded particles of natural sand resulting in higher strength. The excessive bleeding of concrete is reduced by using artificial sand.

What Is Silica Sand & How Is It Different From Regular Sand?

Regular sand, also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. For example, typical brown sand used for concrete applications can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium, and other trace elements/minerals.
