Sephaku 42 is a 42,5R early strength cement ideally suited where faster demoulding or striking/striping of formwork is beneficial. Ideal for all types of building and civil work and suitable for ready-mix and site-batched concrete, mortar and screeds.


Sephaku 42R is a type CEM II/A-V 42,5R early strength cement and is manufactured to fully conform to the requirements of strength class 42,5R in accordance with South African National Standard SANS 501971:2013.

Sephaku 42R is rated ‘R’ in terms of early rapid strength development which makes it ideally suited where faster demoulding or striking/stripping of formwork is beneficial.

Benefits

Ideal for all types of building and civil work

For use in the manufacture of concrete products

Suitable for ready-mix and site-batched concrete, mortar and screeds

Exhibits early strength which improves stripping time

Benefits of reduced water demand make concrete easier to flow and pump, resulting in improved surface finish
