As a cement modified against moderate sulfate attack , Type II Cement is more resistant than ordinary Cement and it is used in underground waters or soil containing little sulfate (water shoud be less than 1200 ppm and the soil less than 0/5% ) and , also , due to its low heat generation it is used in bulk concreting
