Why use an Arthur Brick Press to produce bricks?

  • The machine is economical both to produce the bricks and the cost of purchasing the machines
  • The bricks are of predictable quality, size and compressive strength
  • The machine is robust and constructed using modern production techniques
  • It is South African developed and manufactured

Bricks that are being manufactured on this site are made using a 10% cement mixture which, after curing will produce a brick ± 7 MPa. This is absolutely adequate for single storey building. Using a higher % in the mix the resulting brick can comfortably achieve a 12-15 MPa compressive strength in accordance with the SABS 1215:2008 specification.

 

This picture shows a cured brick which has cured to a pretty pink colour due to the natural oxides in the soil. The other bricks in this picture are freshly made and uncured

Bricks that are being manufactured on this site are made using a 10% cement mixture which, after curing will produce a brick ± 7 MPa. This is absolutely adequate for single storey building. Using a higher % in the mix the resulting brick can comfortably achieve a 12-15 MPa compressive strength in accordance with the SABS 1215:2008 specification.

These bricks have been cured for 3 weeks which is more than necessary to commence construction. Bricks can be used after 10 – 12 days.

As can be seen the brick undergoes a significant colour change in the curing process without any significant shrinkage due to the efficient compression achieved by the Arthur Brick Press. The edges of the bricks are clearly defined.

The final brick colour is influenced by the oxides occurring naturally in the earth used for the bricks.The brick colour can be changed by adding oxide colouring.
