Longcliffe supplies Calcium Carbonate powders to BS7979 specification for use in combination with CEM I Portland cement strength class 42.5 or higher, which conforms to BS EN 197-1 as a component of concrete, mortars and grouts. The benefits of this are that the carbon footprint of the concrete product is greatly reduced and cost savings in mix design are achieved.
