AAC Introduction

In 1914 the Swedes formulated a mixture of cement, lime, water and sand that expanded due to aeration upon addition of aluminium powder. A material like wood but without the disadvantages of combustibility, decay and termite damage was obtained. The material was further developed to what we know today as Autoclaved Aerated Concrete (AAC).


Autoclaved Aerated Concrete (AAC) is a fully integrated building system of panels and blocks that are used for residential, commercial and industrial buildings. AAC, a light-weight green building material, is fire resistant and has good thermal insulation, solid structure and is easy to work with. AAC is manufactured by about 200 plants in 35 countries and is used extensively in residential, commercial and industrial buildings.


Biltech Building Elements Limited is engaged in mechanised manufacture of this revolutionary building material in India. Currently BBEL has over 40% of the market share with a capacity of 10, 50, 0000 cu.m. per annum. Factory manufactured BILTECH products, make constructive use of pollutant Fly Ash, copiously spewed by Thermal Power Stations.
