Physical Properties of Cement – Construction How
· The cements of interest in the making of concrete have the property of setting and hardening under water by virtue of a chemical reaction with it and are, therefore, called hydraulic cements. Hydraulic cements consist mainly of silies and aluminates of lime, and can be classified broadly as natural cements, Portland cements, and highalumina cements. Physical Properties of .
