The cement and water slurry are combined with a pre-formed foam (surfactant). This distributes a multitude of discrete air cells uniformly throughout the mixture. As the concrete hardens, the bubbles disintegrate leaving air voids of similar sizes to create a lightweight concrete.

Aircrete is very versatile and can be modified and adjusted for project size and need. There are many different mix design recipes depending on the application. The process for making aircrete yourself requires only basic skills and basic tools.


Below will be the open source recipe for making lightweight bricks or blocks suitable for a dome structure.
