What is Silica Sand? 9 Major Uses of Silica Sand
Silica Sand is also known as Quartz Sandas it is the derived product of Quartz. With the friction of water and wind, quartz broke down into tiny granular molecules. Thus, Silica Sand is formed. They are fine non-crystalline molecules of SiO2. The mineral composition of Silica (SiO2) is a mixture of Silicon and Oxygen. They can …See more on constructionkart.in
