Autoclaved aerated concrete AAC is made with fine aggregates cement and an expansion agent that causes the fresh mixture to rise like bread dough. In fact this type of concrete contains 80 percent air. In the factory where it is made the material is molded and cut into precisely dimensioned units. Cured blocks or panels of autoclaved.
Autoclaved Aerated Concrete. AAC blocks are Lightweight Non-Load bearing High-insulating Durable building products which are produced in a wide range of sizes and strengths. One size of block is equivalent to seven7 pieces of common bricks.

Now lets look through 6 disadvantages of aerated concrete The production cost per unit for AAC Block is higher. Needs care during manufacture so that final surface of the aerated concrete is not too smooth. as this make it more difficult to apply finishes. due to high water absorption finishes required to breath to prevent environmental.

AAC Autoclaved Aerated Concrete Blocks - Its a Fire Resistant AAC blocks Sound Proof Earthquake Resistant Faster Construction Long lasting Cost Saving Moisture Resistance Environment Friendly Lightweight Perfect Size and Shape amp; High Resistance to Water Penetration.
Autoclaved aerated concrete AAC is a lightweight precast foam concrete building material suitable for the production of concrete masonry unit CMU blocks composed of quartz sand calcined gypsum lime cement water and aluminum powder AAC products are cured under heat and pressure in an autoclave.. Cellular concrete is moistened through steam at atmospheric temperatures although high.
Disadvantages of AAC Blocks. Installation during rainy weather aircrete is known to crack after installation which can be avoided by reducing the strength of the mortar and ensuring the blocks are dry during and after installation. As the AAC Blocks are brittle nature they need to be handled more carefully than clay bricks to avoid breakage.
Buildings close to AAC production facilities benefit from short transportation and minimal shipping costs especially since this concretes lighter weight makes it easier to transport than regular concrete. However AAC itself has an initial cost per unit higher than ordinary concrete.
Autoclaved aerated concrete or AAC is concrete that has been manufactured to contain lots of closed air pockets.
