What is foam concrete?

Foam concrete is a type of lightweight concrete manufactured using cement, sand or fly ash and foam. It is produced by adding a specialised foaming agent to a mix that contains water, Portland cement and fine sand.

It is used as an engineered non-structural fill, in precast panels, as thermal and acoustic insulation and as a refractory material. It is a light-weight, high-performance construction material that can be easily transported and used in many environments.

What is the optimum ratio of water to cement in foam concrete?

The optimum water-to-cement (w/c) ratio in foam concrete is dependent on the foaming agent and the density of the foam. The plasticizer that is added to the mixture is also important to improve the strength.

What is the best way to mix foam concrete?

It is a good idea to start with a concrete mix that has been formulated to suit your needs. The water-to-cement (w/c) and sand-to-cement (s/c) ratios are very important to determine the strength of your concrete.

What are some of the different kinds of foaming agents that can be used?

The most common form of foaming agents are hydrolyzed proteins and synthetic surfactants. Synthetic surfactants can be less expensive and easier to handle than protein-based foam agents.

Another form of foaming agents is a combination of a surfactant and hydrogen peroxide. This method produces a geopolymer foam with more connected pores than a surfactant alone.
