NXTBLOC, Aerated autoclaved concrete(AAC blocks are a high quality building material that offers a unique combination of strength, low weight, thermal insulation, sound absorption, unsurpassed fire resistance and unprecedented build ability. AAC is a steam-cured mix of sand or pulverized fuel ash(PFA), cement, lime and aeration agent. The high-pressure steam-curing in autoclaves achieves a physically and chemically stable product with an average density being approx. one fifth of normal concrete and one fourth of clay brick.
AAC comprises myriads of tiny non-connecting air bubbles which give AAC its incredibly diverse qualities and make it a terrific insulator. AAC is a natural and non-toxic construction material, saves energy, and is friendly to your environment.
