Building with AAC| Concrete Construction Magazine
Autoclaved aerated concrete is manufactured as blocks or panels. Shown here are panels being placed for residential walls. Unlike concrete masonry units, AAC blocks are solid, with no molded core holes. Standard blocks are 8 inches high, 24 inches long, and 4 to 12 inches thick. An 8x8x24-inch block weighs only 35 pounds, so it's …

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.
