Calcium Aluminate - an overview | ScienceDirect Topics

Calcium aluminate cements (CACs) represent an interesting alternative because their pore water pH, ranging from 11.4 to 12.5, is reduced as compared to OPC (Goñi et al., 1991). The main difference between Portland and calcium aluminate cements lies in the nature of the active phase that leads to setting and hardening.

How concrete is made - material, manufacture, making, how to make, used, processing

The manufacture of concrete is fairly simple. First, the cement (usually Portland cement) is prepared. Next, the other ingredients—aggregates (such as sand or gravel), admixtures (chemical additives), any necessary fibers, and water—are mixed together with the cement to form concrete. The concrete is then shipped to the work site and placed
