Inorganic Cementing Materials

Supplementary Cementing Materials (SCM) have been used for decades to replace fractions of pure Portland cement in concrete applications. These powdered materials can be from natural or industrial origins, and are usually considered as latent hydraulic or pozzolanic as they can react to improve the mechanical properties and durability of the concrete.
