of cement. For example, in the US it sells for 15 less than Portland cement.4 In some countries, up to 80 of the cement contains granulated BF slag.5 Using slag prevents it going to landfill as waste, saves energy and natural resources, and significantly reduces CO 2 emissions in cement production. According to the Slag Cement
