Since its invention in 1920, cellular concrete tackled the search for an industrial material that had similar characteristics to wood. It was lightweight, could be cut or perforated, and avoided some of its disadvantages; for instance, its water absorption and need for maintenance. Nowadays, Autoclaved Aerated Concrete (AAC) blocks are actively present in the marketplace by manufacturers like Hebel or Retak, which are building an easy to use and efficient constructive system. If you ever wondered about how to build with these masonry ingredients, it is pertinent to dig a bit deeper into the advantages of this material.
It is a prefabricated material – with binders (mainly concrete and a portion of lime), fine aggregates, water, and an expanding agent – which can be used both to build bearing walls and partition walls. Same as with common or concrete bricks, these work together when applied and mixed with mortar.
