Environments | Free Full-Text | Calcium Sulfoaluminate

Calcium sulfoaluminate (CSA) cements are special cements, namely hydraulic binders obtained from non-Portland clinkers. They are characterized by a high mechanical strength at early ages, rapid-hardening, high impermeability, and chemical resistance, as well as low drying shrinkage and solution alkalinity [20,21,22].CSA cements have aroused the interest of the international cement research
