Working Safely With Concrete

All materials used to make concrete—portland cement, coarse aggregate, sand, and water—are quite heavy even in small quantities. When lifting heavy materials, your back should be straight, legs bent, and the weight between your legs as close to the body as possible. Do not twist at the waist while lifting or carrying these items.

What is the purpose of adding gypsum in 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 of water leaving no time for concrete placing.

How Cement Tiles are Made (Video) | Villa Lagoon Tile

Cement tiles may use more precisely controlled ingredients than structural concrete, but the basic process is the same. Cement cures and hardens chemically over time. It is not that the cement dries, but that it goes through hydration and carbonation, chemical reactions that converts the calcium oxide in the Portland cement to calcium hydroxide, and eventually calcium carbonate.
