India’s pioneering provider of
Autoclaved Aerated Concrete (AAC) Blocks
AAC BLOCKS : Features
Thermal Insulation :
An AAC Blocks with very low thermal conductivity keeps interior remain cool in summer and warm in winter and best for both internal and external construction.
Earthquake Resistance :
Earthquake forces on structure are proportional to the weight of the building, hence AAC blocks shows excellent resistant to earthquake forces. Regions of the seismic activities like exclusively use AAC blocks. It has been proven to withstand wind loads of category 5 tropical storms.
Energy Efficient :
AAC block reduces interior temperature variation marinating pleasant and healthy temperature for habitant. AAC block reduce energy cost of air-conditioning to a great extent due to its thermal property. AAC blocks uses fly ash (70% of its weight), thus provides the most constructive solution to the nation’s fly-ash utilization problem.
Fire Resistance :
AAC blocks are fire resistant up to 4 to 6 hours depending upon thickness. The melting point of AAC blocks are over 1600 degree Celsius, more than twice the typical temperature in building fire 650 degree Celsius.
Pest Resistance :
AAC blocks are inorganic, insect resistant and solid wall construction material. Termites and ants do not eat or nest in AAC blocks.
Water Barrier :
AAC Block’s water barrier properties are further enhanced by adding silicone based additives.
Cost Saving :
One AAC block of size is equivalent to 8 red bricks hence it reduces 1/3rd of joints resulting in saving of mortar up-to 66%. AAC blocks are automatic machine cut having accurate dimensions resulting in thinner coat of plaster as compared to clay bricks. It saves mortar in plaster to 35% to 40%and having advantage in carpet area. Even this dead weight reduction leads reduction in consumption of steel and cement and lesser excavation for foundations.
Green Product :
AAC block is 100% Green building material & is a walling material of a choice in LEED certified buildings. In India itself AAC blocks has potential to avert 200mn tones of CO2 emissions into environment – a saving of $20 billion every year.
Sound Absorption :

Good sound absorption qualities due to porous structure of blocks. AAC blocks have an excellent Sound transmission Class (STC) rating of up to 45 db. Therefore it is an ideal material for wall construction in hotels, auditoriums, studios, hospitals etc.

Long Lasting :
Higher strength of the AAC block gives higher structural stability than conventional bricks. AAC being steam cured above 200-230 degree C and at 15 kg /cm2 pressure becomes inert and does not have any effect of water damage or weather damage on it.
