AAC Blocks: A Revolution in Construction Industry
Autoclaved Aerated Concrete (AAC) is an ultra-light precast concrete
masonry product. It can weigh as little as 1/5th of the ordinary concrete due
to its distinct cellular structure, featuring millions of tiny pockets of trapped
air. This cellular structure gives AAC a number of exceptional physical
characteristics. The finished product is up to five times the volume of the
raw materials used, with an air content of 70% to 80%, depending on the
required strength and density. Due to this large increase in volume, AAC is
very resource-efficient.
A truly green material, fly ash, which is the waste material generated by
thermal power plant, is utilized in the manufacture of AAC products. This
aids in saving the natural resources, on one hand, and on the other hand,
assists in converting the industrial waste into productive use. This makes
AAC blocks one of the best examples of a truly ‘green product,’ in every
sense of the term.
Its major features that makes it unique and effective are:
x AAC has high thermal efficiency;
x AAC structure are well-suited to withstand fires, earthquakes, and
other natural disasters; and
x AAC reduces noise pollution and improves indoor air quality
Guru Ganesh AAC Block Udhyog has been producing these AAC blocks
since 2018. These blocks are available in three sizes: 8 inches, 6 inches,
and 4 inches thickness; the face dimension for each size is
8 inches x 24 inches.
