Sephaku 32 is a type CEM IV/B 32,5R General Purpose blended Portland Cement and fully complies with the requirements for a Pozzolanic Cement in South African National Standards (SANS) 50197-1.
‘R’ denotes early strength and the addition of high grade fly ash ensures professional quality, 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 that forms the base cement being replaced by an alternative cementitious addition.
For more specialised structural concrete applications the use of Sephaku 42,5N or Sephaku 42,5R should be considered.
Guideline proportions in the tables below allow for a nominal 5-10% wastage.
1 wheelbarrow load of cement in volume = 2 x 50 kg bags.
