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. With its manufacturing facilities in north, east and western India, and some more plants coming up in other parts of the country to facilitate pan-India presence and reach, BILTECH commands the status of the largest Fly Ash based AAC manufacturer in India.
AAC Benefits & Advantages
AAC Benefits
What is AAC?
Autoclaved Aerated Concrete (AAC) is a certified green building material, which can be used for commercial, industrial and residential construction. It is porous, non-toxic, reusable, renewable and recyclable.
When was AAC first developed?
AAC was developed in 1924 by a Swedish architect, who was looking for an alternate building material with properties similar to that of wood – good thermal insulation, solid structure and easy to work with – but without the disadvantage of combustibility, decay and termite damage.
What are Biltech ACE blocks/panels made of?
Biltech ACE blocks and panels are manufactured using fly ash mixed with cement, lime, water and an aerating agent. The resultant building material, comprising millions of tiny air pores, is set and cut into blocks and panels of varying sizes.
What are the advantages of using Biltech ACE?
Eco-friendly & Sustainable
Makes productive use of recycled industrial waste (fly ash).
Non-polluting manufacturing process – the only by-product is steam.
Made of non-toxic ingredients.
Does not exude gases.
Total energy consumption for producing Biltech ACE is less than ½ of what it takes to produce other building material.
Lightweight
3-4 times lighter than traditional bricks, therefore, easier and cheaper to
transport.
A Biltech ACE block weighs approximately 50% less than a standard CMU block.
A Biltech ACE panel weighs approximately 30% of standard cast-in-place concrete.
Usage reduces overall dead load of a building, thereby allowing construction of taller buildings.
Thermally Insulated & Energy Efficient
Tiny air pores and thermal mass of blocks provide excellent thermal insulation, thus reducing heating and air conditioning costs of a building.
Fire Resistant
Non-combustible and fire resistant up to 1600° C.
Can withstand up to 6 hours of direct exposure.
Acoustic Performance
Superior sound absorption qualities due to porous structure of blocks.
Offers sound attenuation of about 42 dB, blocking out all major sounds and disturbances.
Ideal for schools, hospitals, hotels, offices, multi-family housing and other structures that require acoustic insulation.
Easy Workability and Design Flexibility
Blocks can be easily cut, drilled, nailed, milled and grooved to fit individual requirements.
Available in custom sizes.
Simplifies hydro-sanitary and electrical installations, such as pipes or ducts, which can be installed after the main construction is complete.
Seismic Resistant
Lightweight blocks reduce mass of a structure, thus decreasing the impact of an earthquake on a building.
Non-combustible nature provides an advantage against fires, which commonly accompany earthquakes.
Precision
Available in exact sizes.
Results in smooth walls with perfect contact between different elements.
Reduces cement and steel usage.
Termite/Pest Resistant
Due to structure of blocks, Biltech ACE cannot be damaged or infested by termites and other pests.
Low Maintenance
Reduces operating cost by 30% to 40%.
Reduces overall construction cost by 2.5% as it requires less jointing and reduces need for cement and steel.
High-insulation blocks save up to 30% in energy costs.
Variety in sizes of blocks helps increase carpet area.
Wall painting and plastering last longer as almost nil efflorescence affects Biltech ACE. This translates into lower maintenance costs.
Faster Construction
Reduces construction time by 20%.
Different sizes of blocks help reduce the number of joints in wall masonry.
Lighter blocks make construction easier and faster.
Easy to install. Sets and hardens quickly.
