Effect of different forms of silica on the physical and mechanical properties of gypsum plaster composites. Gypsum plaster/silica composites prepared by dry blending (0.210 %) natural sand, silica fume or silica gel and subsequently hydrated. Their physical and mechanical properties, including normal consistency, setting time, apparent
PROPERTIES OF PLASTER. Durable : Resistance to moisture penetration. Gypsum acts as a protective layer, which prevents water particles from spinning through the layer, and therefore creates cracks between the layers. Workable : Sufficient water in a mixture of cement and sand. The water used must be potable, free of chloride and impurities.

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
