Portland cement 2 Kordestan cement

This type of cement is manufactured in accordance with the specifications of Iranian National Standard ISIRI-389 and American Standard ASTM-C150 and has a maximum C3A content of 8%. The initial and final strength of its standard mortar is lower than that of Type 1 cement. Type 2 cement, as modified cement, is more resistant to moderate sulfate attack than conventional cement. It is advisable to use this type of cement in hot weather, which increases the risk of ordinary concrete temperatures to more than 320 ° C and bulky concrete that exceeds 150 ° C.
