What Is AAC?

AAC (Autoclaved Aerated Concrete) Industry is an emerging sector worldwide especially mega populated countries like India. It is famous construction material in the option of Traditional red clay brick, Cement brick etc. It is useful in residential, commercial and industrial construction activities.It is an ultra-light concrete masonry product.AAC was developed in 1924 in Sweden with a motive to develop a material which had the benefits of workability like wood and durability like concrete. AAC is a long proven material. AAC block is used in a wide range of application and has been in use in EUROPE over 90 years, the Middle East for the past 40 years and in America and Australia for 25 years. It's an estimate that AAC now account for over 40% of all construction in UK and more than 60% of construction in Germany. In India production of AAC block started in 1972.

AAC consists of basic materials that are widely available. These include sand, cement, lime, fly ash, gypsum, aluminium powder paste, water and an expansion agent. Silica sand, the raw material used in the greatest volume in AAC, is one of the world's most abundant natural resources. The AAC Mix is fully cured in Autoclaves using Steam at high pressure and temperature which gives AAC Blocks the highest strength to weight ratio among various commonly using building materials.

By considering the ecofriendly and flexible nature AAC block, it becomes first choice of Civil Engineers, Constructors, Builders and developers. AAC block is a light weight precast building material that provides both construction economy and speed. It is manufactured using 60-65% of fly ash (by weight), an unavoidable waste from coal/lignite-based thermal power plants.AAC blocks are lightweight, energy-efficient, fire-resistant and an excellent thermal insulator. The blocks are extremely lightweight and thus suitable for internal as well as external construction.The high consumption of raw materials by the construction sector, results in chronic shortage of building materials and the associated environmental damage. In the last decade, construction industry has been conducting various researches on the utilization of easily available raw materials in construction. AAC is one of the materials which can cope up with the shortage of building raw materials and can produce a light weight, energy efficient and environmentally friendly concrete.

Construction world is changing, in fact it needs more accurate, strength, cost effective inputs. AAC industry will definitely fulfill this demand to give best outputs.
