What is the primary component of cement plaster?

Cement plaster is primarily composed of a mixture of cement, sand, and water. This combination allows it to serve as a protective and decorative finish for walls and ceilings in commercial buildings. It provides strength, durability, and resistance to weathering and other environmental conditions.

While gypsum plaster is a different type of plaster that primarily utilizes gypsum as its main ingredient for applications typically involving interior finishes, the question specifically asks for the primary component of cement plaster. Therefore, the most straightforward and accurate answer is that cement plaster is indeed the primary component being referenced, as it defines the material used in the plastering process itself.

Other choices that mention gypsum plaster or a combination of both would not apply because they don't accurately represent the primary component involved in cement plaster.
