Finecrete walling material is the lightest because it contains very high volume of air.
Formed as a result of reaction of Aluminium on a proportionate blend of lime, cement and flash, the Hydrogen gas that escapes creates millions of tiny cells giving it strong honeycomb structure. It is further strengthened by high pressure steam in autoclaves
The unique cellular structure provides excellent fire rating. Due to this cellular structure AAC blocks do not disintegrate even in fire. The Finecrete material has best in class fire rating of 4 hours. The melting point of AAC blocks are over 1600˚C, more than twice the typical temperature of fire which is 650˚C.
The light weight blocks show excellent resistance to earthquake forces. Regions of high seismic activities like Japan exclusively use AAC blocks. It has been proven to withstand wind loads of category 5 tropical storms.
With their closed air pockets, AAC lightweight blocks can provide very good sound insulation / sound absorption with an STC (Sound Transmission Class) rating of 44. It can also be used as a sound barrier wall along busy roads. Result, virtually sound proof interiors!
Our products enjoy the highest thermal rating in the industry, R301. Its cellular structure provides well insulated interior, keeping out warm air in summers and cold air in winters. AAC reduces cost of air conditioning upto 30%.
Microscopic Structure of lightweight block does not allow for capillary action making it impervious to water. Its water barrier properties are further enhanced by adding silicon based additives.
High pressure steam-curing autoclaving process gives AAC blocks unmatchable strength to weight ratio, higher than even M 150 concrete, and far exceeds the Indian Building Code requirements.
AAC is 100% green building material & is a walling material of choice in LEED certified buildings (ITC centre the highest rated green building has been build using AAC)
AAC is the most energy and resource efficient in the sense that it uses least amount of energy & material per m3 of product.
Unlike brick manufacturing process which uses precious layer to layer agricultural soil and is being one major cause of high fertile soil erosion. AAC uses fly ash (65% of its weight), thus provides the most constructive solution to the nation's fly-ash utilisation problem.
With solid wall construction and finishes, there are fewer if any, cavity for insects and rodents to dwell in. Termites and ants do not eat or nest in AAC blocks. Being made up of in-organic minerals, light weight blocks does not promote growth of molds.
Finecrete is one of India's most reliable manufacturers of technologically advanced AAC Blocks and Panels. The company's standing goes back to over three decades, for having produced high-quality marble, granite and other stones for more than 35 years.
