1. Batching: The process of measuring different concrete materials such as cement, coarse aggregate, sand, water for the making of concrete is known as batching. 2. Mixing: In this process, all the materials are thoroughly mixed in required proportions until the paste shows uniform color and consistency.

General Purpose Cement (or GP Cement) is straight cement. GP cement is manufactured from Portland cement clinker, gypsum and limestone. GP cement is used in all types of building and construction. ... Builders Cement (or General Purpose Blended (GB) cement) contains both GP cement and a nominal mass of fly ash.

The MgO is cast in a liquid slurry-like form (a mixture of MgO powder, and other additives and water) and sets up by chemical reaction - much like Portland cement does in stucco or concrete. The cast boards are then cured at ambient temperature.

Common materials used to manufacture cement include limestone, shells, and chalk or marl, combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. When heated at high temperatures, these materials form a rock-like substance which is ground into the fine powder; this is cement.
