We offer two extremely versatile, CEM II early strength cement types in the 22,5X and 42,5R strength classes. The difference between the two is dependent on the strength gain over different time periods, as well as application.
We are a primary producer and our products comply with SANS 50197-1, bearing the SABS mark of approval.
Not all cements are made equal. Our cement is produced in the newest cement plant in South Africa using a high quality limestone deposit. Mamba Cement is pure in performance meaning that contents have cementitious properties.
Mamba 42,5R consists of cement clinker, gypsum and limestone, in accordance with defined CEM II specifications.
