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 ...

Lighter, more fire-resistant, and a better insulator, autoclaved aerated concrete caught on in the rest of the world ages ago. It's taking a lot longer in the U.S. The porous AAC structure comes from being "leavened" with aluminum.
