  • How is autoclaved aerated concrete (AAC) made? - Quora

    Apr 21, 2017· An autoclave is a low temperature furnace that adds humidity and pressure to the environment. When the autoclave is closed the heat, humidity and pressure cook the blocks or other preformed shapes and cause the chemical reaction forming the bubbles to appear. AAC has many interesting and valuable properties. First of all it is a lightweight

  • What are AAC(Autoclave Aerated Concrete) Blocks and what

    Jun 11, 2013· Water Barrier: The AAC blocks have macro pores in its structure instead of micro pores. These macro air pores are formed at the time of production of AAC blocks and are uniformly spread all over the blocks. Macro pores block capillary action and absorption of water in AAC blocks is minimal.
