Sephaku 42 is a 42,5N (CEM ll/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.
For more specialised structural concrete applications, the use of Sephaku 42,5R or Sephaku 52,5N should be considered.
Ideal across a wide range of building and civil work
For use in the manufacture of concrete products
Suitable for all types of ‘home’ concrete
Extremely versatile and general purpose product for a wide range of concrete, mortar and screed applications
Less water to produce a cohesive mix and long-term durability
GUIDELINE PROPORTIONS FOR TYPICAL APPLICATIONS (BY VOLUME)
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.
HIGH STRENGTH CONCRETE
Improved water tightness, columns, slabs and heavy-duty industrial floors.
25 - 30 MPa
MEDIUM STRENGTH CONCRETE
Paths, driveways and light-duty floors.
20 - 25 MPa
LOW STRENGTH CONCRETE
Foundations, footings, ‘home’ concrete, e.g. domestic flooring, steps, paths and fencing.
