Acc Block
Autoclaved Aerated Concrete blocks are made from mixing sand, cement, lime,
water and gypsum. They are then cut into pieces and form into cells that are
subsequently autoclaved to harden, creating cellular foam blocks. They have a number of
features such as being lightweight, having good fire resistance and excellent acoustics;
plus they offer thermal insulation, making them an increasingly popular choice for
construction projects around the world.
Autoclaved Aerated Concrete (AAC) blocks are the preferred choice of
walling material for almost every real estate developer in the market today because
they’re cheap and enable faster construction. But they aren’t easy to live with. We’ve
learned about the lengths these guys scale to make it all work from our own first-hand
encounters with the construction teams at project sites. The blocks are very porous and
absorb huge amounts of water; the expansion and contraction are so much that they
eventually crack; the plaster de-laminates after a few years of construction; and the
structural integrity gets compromised if the chiselling for concealed conduits is not
done accurately.
