This is achieved by adding a water-reducing agent such as polycarboxylate superplasticizer to the base slurry. This reduces the amount of water required to achieve the desired fluidity, while improving the workability and strength of the finished product.

Foam concrete can be mixed dry or wet. In the wet method, a standard ready mix truck is filled with the base material and then mixed with the foam, which is injected into the mixer as it’s mixing. This ensures the foam is fully incorporated into the mortar, and is a more reliable system than mixing it in by hand.
