Sephaku 32 is a 32,5R general purpose blended cement and fully complies with the requirements in South African National Standards (SANS) 50197-1.
The ‘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.
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.
