The autoclaving process requires significant amounts of energy. AAC is lighter and uses less resources to transport than ordinary concrete block, but is still heavier than many other materials. Depending on the project location, AAC could increase its carbon footprint over one built with locally available supplies.
Are AAC blocks strong?
AAC is strong enough to use for structural parts of a building, but isn't as strong as conventional concrete. According to the Portland Cement Association, autoclaved aerated concrete has an allowable shear stress of 8 to 22 psi, and a compressive strength of 300 to 900 psi.
Is aerated concrete strong?
Durability Autoclaved aerated concrete blocks are very strong and they far outlast that of their ordinary counterparts. The blocks consist of materials that are not biodegradable and repel mold. Because of their great strength, AAC blocks are more stable as well.Apr 3, 2018
What is aerated concrete used for?
What is aerated concrete used for? Aerated concrete is commonly used as a building material for making walls, floors, and roofs.Apr 3, 2018
Where is autoclaved aerated concrete used?
Autoclaved aerated concrete is factory-made, and the material is molded into blocks or slabs with precise dimensions. These can be used for walls, floors and roofs. Similar to all cement-based materials, AAC elements are strong and fire resistant.
What are autoclaved aerated blocks?
Autoclaved aerated concrete (AAC) is made with fine aggregates, cement, and an expansion agent that causes the fresh mixture to rise like bread dough. Cured blocks or panels of autoclaved aerated concrete are joined with thin bed mortar. Components can be used for walls, floors, and roofs.
