Autoclaved Aerated Concrete or AAC is concrete that is specially manufactured to intact closed air pockets, which makes it light weight and easily moldable as per the construction requirement. AAC is fairly light weight and energy efficient, as it is manufactured by adding foaming agent to concrete, rather than molding it in block shape and then cooking them with steam i.e. autoclaving. AAC is relatively easy to work with and can be shaped accordingly with hand tools. AAC can also be used in panel form for floor and roof construction activities.
The global autoclaved aerated concrete market is witnessing significant growth, due to increasing industrialization and accelerated urbanization in developing countries, cost effectiveness and light weight material of AAC, and increased emphasis on sound proof and green building. Now-a-days with infrastructure development, environmental conservation has also become key area of concern, as traditional building materials, such as wood and fired clay bricks, implies cutting of green trees and consume lots of fertile land/soil and emit huge amount greenhouse gases. Another factor for increasing demand of AAC is that it’s an environment friendly product, as it is manufactured by using fly ash (approximately 60-65% by weight), which in an unavoidable waste from coal based thermal power plants.
The rapid industrialization and infrastructure development in the emerging economies of Asia-Pacific has shown substantial growth in the global autoclaved aerated concrete market. The growth in residential and commercial buildings, construction of highways, bridges and tunnels are the major contributors in increasing the demand for autoclaved aerated concrete. Additionally, the increasing purchasing power of individuals, improving life style, along with consumption trends and technological advancements has led to development of more varied, complex and eco-friendly products, which is positively driving the growth of the AAC market. Moreover, the increasing focus on green building construction and sound proof building is further boosting the demand of AAC.
Among the various applications, the construction materials segment held the largest share in the global autoclaved aerated concrete market in 2015, and it is anticipated to retain its dominance during the forecast period. However, the bridge sub-structure segment is anticipated to witness the highest growth during 2016 – 2022, owing to increasing investment in bridge construction. Moreover, the concrete pipe and void filling segments have been the emerging application segments in global AAC market in 2015. Among the various end-users, the infrastructure segment dominated the global AAC market with consumption of 28.1 million cubic meters in 2015, and it is anticipated to continue with its dominance during the forecast period. Moreover, The residential building segment is expected to be the fastest growing end user segment during the forecast period.
The global autoclaved aerated concrete market was estimated at $3,753.66 million in 2015, and it is expected to grow at a CAGR of 8.1% during 2016 – 2022. In terms of volume, Europe accounted for the largest share in the global autoclaved aerated concrete market with 21.3 million cubic meters consumed in 2015. The major reasons behind the growth of the market in the region include shifting trend to light weight and green building construction. Asia-Pacific was the second largest market in the global autoclaved aerated concrete market with 19.7 million cubic meters consumed in 2015.
The key companies operating in the global autoclaved aerated concrete market includes Isoltech srl, Xella Group, Cematrix, SOLBET Capital Group, Laston Italiana S.P.A, Aerix Industries, ACICO, Broco Industries, Aircrete Europe.
