Sephaku 42
Sephaku 42 is a 42,5N general purpose blended cement and is extremely versatile. This is a general purpose product for a wide range of concrete, mortar and screed applications.
Sephaku 42N is a 42,5N (CEM II/A-L or CEM IV/A-V) general purpose cement and fully complies with the requirements for a strength class 42,5N in the South African National Standard SANS 50197-1:2013. The ‘N’ denotes normal strength gain and the addition of high-grade cement extenders ensures professional quality and less water to produce a cohesive mix and long-term durability. Sephaku blended cements have lower embodied CO2 as a result of a proportion of the clinker of the base cement being replaced by a high grade alternative cementitious addition.
