How and why did I come to specialize in designing and building with Autoclaved Aerated Concrete (AAC)?
Autoclaved aerated concrete designs is made with completely inorganic, sustainable materials and there is no waste byproduct in its production. Unlike conventional formed concrete blocks (CMU) which is made with cement and course fine aggregate it is made with sand, lime a special kind of white clay and cement.
It is mixed with water in large square forms and aluminum oxide is added to the slurry and this causes a chemical reaction to occur. This reaction causes thousands of tiny hydrogen bubbles to rise in the mix and the slurry rises like yeast in bread dough. The result is millions of tiny air pockets are trapped in the concrete as it begins to cure. It is then placed in autoclaves to provide heat and pressure to cure it to its intended compression strength.
