CEMEX Extra is a factory produced Portland-fly ash Cement that complements our range of Portland (CEM I) cements. The enhanced properties of the product provide benefits in a wide range of concrete, mortar, render, screed and grout applications. CEMEX Extra is manufactured by burning a precisely specified mixture of raw materials containing Lime, silica, alumina and small quantities of other materials to form a clinker. The clinker, a selected fly ash and calcium sulfate, (to control setting), are inter-ground to produce a very consistent cement with improved characteristics. CEMEX Extra is suitable for use as an alternative to Sulfateresisting Portland cement in most aggressive ground conditions.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that CEMEX UK is consulted before specifying.
