Foam Concrete Agent

A diy foaming agent is a liquid chemical that can be used to make concrete foam. They contain anionic, amphoteric and nonionic surfactants and some preservative agents.

Some of these are very common for making concrete and others have less widespread use. It is important to check the label of the product for what it is intended to be used for and where.

Adding a protein based foaming agent to the cement mixture increases its strength and compressive properties. It has been reported that it increases compressive strength by over 80% compared to foamed concrete made with synthetic foaming agents [13].

The protein based foaming agent contains a stabilizer that may build up at the interface of air bubbles, preventing them from collapsing into smaller spheres. The stability of these spheres is also increased by hydrogen bonding between the water and the foaming agent.


The density of foam concrete depends on the ratio of water to cement and the type of aggregate. In addition, the density of foam concrete is also affected by other factors. For example, using RCA instead of river sand decreases the dynamic elastic modulus and increases the pore size.


The microstructure of foam concrete can be changed by changing the water/cement ratio, which affects the pore diameter and distribution. Higher w/c ratios cause thinner-walled and irregular foams with a poorer bubble holding ability, which negatively affects its compressive strength.

The stability of foam concrete is a complex issue that has many variables, such as the ratio of water to cement and the type and gradation of aggregate. The w/c ratio can be reduced to an optimal level that increases the compressive strength and improves the microstructure.
