The Essential Components of CemAir™ Superior Lightweight Cellular Concrete

The essential components of CemAir™ are cement powder, water and a variety of additives.

Dependent on the required characteristics of the final product, these ingredients are blended to produce a slurry, then homogenised with cold-formed stabilised foam. Sand may be added to some mixes, as well as fibres added for micro reinforcing.

The final concrete product is well-suited for both civil uses and use in the construction industry.

As well as supplying the chemicals for the concrete, I design, develop and manufacture machinery and systems for the commercial production of CemAir™.
