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

25MPa at 28 days

Description
Used in various diverse applications in both residential & commercial applications. Frequently used in house foundations and general concrete works where high strength is not required.

Application

Residential house/shed slabs
Footpaths and kerbs
Driveways and patios

25MPa at 28 days

High Early Strength
– RMS Approved

Description
Commonly used for time critical projects requiring high early strength, typically
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
