Jun 29, 2020  These vary from lightweight aggregate concrete, foamed concrete, or Autoclaved Aerated Concrete (AAC). The aggregates used in AAC are extremely fine, even smaller than a grain of sand. This composition makes AAC highly suitable for pre-casting and reshaping. AAC structures are so soft that they can be hand-sewn and pierced by nails or screws.
