Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the setting of cement. If not added, the cement will set immediately after mixing ...

Jun 07, 2018 Here we give you brief comparison of Cement Plaster vs Gypsum Plaster 01. Composition. Sand Cement Plaster. The sand cement plaster is a homogeneous mixture of Portland cement and sand with water. The sand and cement are mixed at the site in different ratios. Nowadays it is also available in Ready-made packages. Cement, one of the most important building materials, is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. Cement generally refers to a very fine powdery substance chiefly made up of limestone (calcium), sand or clay (silicon), bauxite (aluminum) and iron ore, and may include shells, chalk, marl, shale, clay, blast furnace slag, slate.

Severe dust problems can be decreased, especially when combined with use of water-soluble polymers. Less pesticide and nutrient residues will escape for the surface of land to reach lakes and rivers when appropriated amendments are used to stabilize the soil.
