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. Nzäm'bu gi esferas 'nehe ar aumenta ir nge ar enlace hidrógeno entre ar dehe ne ar agente espumante.
