Autoclaved aerated concrete (AAC) blocks are an excellent building material that are lightweight and durable.
AAC blocks are made with cement, fine aggregates (such as sand or fly ash), water, and an expansion agent (that causes the mixture to increase in volume); visually, it may look similar to the rising of bread during proofing. When the mixture is completely dry, it contains about 80% air.
During the production process of AAC blocks, the mixture is moulded and cut into units of precise dimension. By adding an expansion agent to concrete mixture, you can get an eco-friendly substitute for red bricks.
AAC Blocks: What Are They Used For?
This concrete-based material can be used for both interior and exterior structures. AAC blocks are suitable for high-rise buildings and structures in places that have a high-temperature variation. Buildings made with AAC blocks don’t usually require separate insulation material. AAC can be made in the form of blocks as well as panes; some of its common applications include multi-storey buildings, residential units and kitchen surfaces.
