This cement is a mixture of blast-furnace slag, PC clinker, and calcium sulphate. The amount of blast furnace slag is usually in the range of 80 to 85 % (not less than 75%), while calcium sulphate is added in the amount of 10 - 15%. Overall, the SO3 content of this cement is controlled to be always greater than 4.5%.
