Its successful entities includes : BILT – Paper & Pulp Crompton Greaves –Power Equipment The Global Green Company- Food processing Avantha Power & Infrastructure – Power generation Solaris ChemTech - Chemical Avantha Technologies – IT & ITES. WHAT IS AUTOCLAVED AERATED CONCRETE : WHAT IS AUTOCLAVED AERATED CONCRETE Autoclaved Aerated Concrete (AAC) is formed by a chemical reaction between finely divided calcareous and siliceous material. AAC has been around for over 80 years. The first documented attempt at autoclaving aerated concrete was in 1923 in Sweden by an architectural science lecturer, Dr Johan Axel Eriksson. Since then, AAC has been used extensively in Europe, Asia & USA. More AAC is produced worldwide than any other building material with the exception of regular concrete. Microscopic view of the crystalline composition of AAC at the cellular level. Microscopic view of the crystalline composition of AAC at the cellular level. AUTOCLAVED AERATED CONCRETE IN INDIA : Hindustan Prefab Limited (HPL), the Government owned company is known to be the first Organisation in India to produce AAC and subsequently HPL has stopped the AAC operation in 1972 . In past few years BBEL along with two more companies Siporex India Ltd. & HIL was catering to the material requirements of Northern, Western and Southern Market respectively. Until recently looking at the demand of alternate walling materials, 6-7 companies has also started manufacturing AAC mostly in western part of India.

The entrained air in the cellular structure of BILTEC AAC system gives the product excellent thermal insulation properties, as well as good heat retention characteristics. These characteristics contribute significantly to the energy saving performance of the building . Fire resistance : Fire resistance AAC is non-combustible. It has one of the highest hourly fire resistance ratings per millimetre of any building material. This makes it an ideal choice for fire protection around steel columns and steel beams, and in the construction of shaft walls, stairwells, corridors and firewalls. A 100mm and a 200 mm non-load bearing wall shall have fir resistance of 2 hours and 6 hours respectively . Earthquake resistance : Earthquake resistance AAC has been used for many years in areas subject to seismic action. Building which consist fully or partly of AAC have in general terms shown good resistance to earthquake forces in practice. The light weight of AAC reduces the seismic forces in common with some other materials. The non combustible and fire resistance nature of the AAC material is an advantage against fires commonly associated with earthquakes. The low weight of AAC in relation to its strength is an intrinsic advantage for earthquake design. AAC permits the designer to reduce the mass of the structure, limiting the impact of accelerations introduced in seismic situation. AAC IS 100% RECYCLABLE : AAC IS 100% RECYCLABLE The waste factor in its construction can be reduced to less than 1% with good construction management. Nearly every piece of the material can be used in the construction of an AAC building. All waste, however, is easily recycled. Is BILTEC –AAC is Green building material? : Is BILTEC –AAC is Green building material? Yes, Up to 65 % raw materials consist of Industrial Waste i.e. Fly ash Yes ,Non-polluting Manufacturing process -only steam is released Yes, Resource Efficient – 4 parts of AAC are manufactured from 1 part of raw material Yes ,Low Energy Consumption throughout Life cycle- The total energy consumption to produce AAC is less than 1/2 that of comparable building materials. Also When installed, AAC results in tremendous energy savings for heating and cooling the building. Yes ,Healthier Indoor Air Quality –AAC does not off gas. AAC does not promote the growth of mildew and mold, and cannot be infested by termites.
