Autoclaved aerated concrete (AAC)
Autoclaved aerated concrete blocks (AAC, sometimes called "autoclaved cellular concrete" or "autoclaved lightweight concrete") are cement-based blocks that are light enough to have reasonable thermal properties while maintaining enough strength to be structural. Unlike typical concrete, quartz sand is the only aggregate and the cement ...

Autoclaved Aerated Concrete (AAC Blocks)
The result is a material that features the strength and durability of traditional concrete, but which weighs a fraction as much. In fact, 80% of AAC is air. Despite how cutting edge and sophisticated it seems, autoclaved aerated concrete has been around since 1924, which is when an architect in Sweden first patented it.

3 Problems with Autoclaved Aerated Concrete Blocks
Sensitivity to Water. One of the biggest disadvantages of autoclaved aerated concrete blocks is the ability of the block to stand up to water over time. The aeration process creates millions of tiny holes or pores inside the concrete block. Water can be retained inside these pores so any finishes applied to the wall must be able to breathe.
