Abstract:
Several types of Portland cement having different characteristics are distinguished. The most important variables are the rare of hardening, the rate and total extent of heat evolution during hydration, and the resistance of hardened cement to chemical attack by sulphate and,chloride solutions. The aim of the present work was to prepare three types of Portland cement, namely types I, II and IV, in the laboratory from locally available raw materials, and to study their hydration kinetics, development of compressive strength as well as the aggressive attack of 4 wt. \% MgCl2 solution on hardened pastes of the three Portland cements and of sulphate resisting cement pastes. The results show that the kinetics of hydration and the susceptibility to corrosion by chlorides increase with increasing LSF of the cement.
