Cement is then pumped to silos for storage and dispatch. Mineral additions and SCMs are added to reduce the amount of clinker in cement. This in turn reduces the fuel power process emissions and raw materials associated with cement production. At the same time it creates a use for material considered to be a waste product of other industries.
