Understanding Plaster Sand: A Comprehensive Guide

Plaster sand, often referred to as plaster of Paris sand, is a crucial component in the construction industry. It is a fine, white powder that, when mixed with water, sets into a hard, durable material. This guide will delve into the various aspects of plaster sand, including its composition, uses, benefits, and precautions.

Composition of Plaster Sand

Plaster sand is primarily composed of calcium sulfate hemihydrate, which is a chemical compound with the formula CaSO4路1/2H2O. This compound is derived from gypsum, a soft sulfate mineral. When heated, gypsum loses its water content and transforms into plaster of Paris, which is then ground into a fine powder to create plaster sand.
