The low C 3 A concentrations reduce the formation of expansive ‘ettringite’ in sulphate resistant cement concrete materials and hence lessen the damage of hardened mortars and concrete deterioration caused by the sulphates (Puppala et al., 2004; Irassar et al., 2000). However, it should be noted that utilizing specialty cements such as Type
