Concrete Strength

Measured in MPa (megapascals) concrete is capable of achieving variable strength depending on the desired application ranging from general groundwork and residential applications (20-25MPa) to commercial grade which typically requires a stronger concrete mix (32MPa+).

For more information of what concrete best suits your project, please see below.

Normal Class Concrete

20-25 MPa at 2 hours, where early stripping of formwork is needed.
RMS-approved design mixes also available

Application

  • RMS roadworks
  • Airport runways
  • Precast concrete
  • Tilt-up concrete

Subbase/Leanmix Concrete
– RMS Approved

Description
A mix where the cement content is lower than the water content. Provides uniform surface to pavements and prevents contact between the ground and the slab.

Application

  • Subbase in pavements
  • Subbase in foundations

No Fines Concrete

Description
Mixture with no fine aggregates, allowing a high concrete void ratio. Such high permeability means the concrete has drainage capacity.

Application

  • Drainage
    Landscaping
  • Civil infrastructure
