Cellular concrete in construction
Lightweight cellular (foamed) concrete is made by mixing pre-formed stable foam and cement-based slurry. Cellular concrete is replacing traditional materials in the construction industry due to its lightweight, high quality and availability.
Cellular concrete can have a range of dry densities, typically from 400 kg/m3 to 1600 kg/m3 and a range of compressive strengths, 1 N/mm2 to 15 N/mm2. It is very versatile, since it can be tailored for optimum performance and minimum cost by choice of a suitable mix design
Accelerated urbanisation, growth in infrastructural activities, and increasing industrialisation have driven the growth of the cellular concrete market. The increasing income and spending capacity of people in developing economies and increasing demand by end-use sectors such as commercial buildings, residential buildings, and infrastructure are the major factors driving the market.
In the UK the use of cellular concrete became popular after it was specified for trench reinstatement in the New Roads and Streetworks Act 1991. Other applications include road sub-bases, ground stabilisation, bridge abutments and strengthening, and land reclamation.
The key companies involved in the market are:
- Propump Engineering (United Kingdom)
- Saint Gobain (France),
- Fillcrete (South Africa),
- Xella Group (Germany),
- Cellucrete (U.S.),
- Cematrix (Canada),
- Litebuilt (Australia),
- Nublok (South Africa),
- Laston Italiana S.P.A (Italy),
- Cellular Concrete Technologies (U.S.),
- Aerix Industries (U.S.),
- ACICO (Kuwait),
- Shirke (India),
- Broco Industries (Indonesia),
- Aircrete Europe (Netherlands).
- EAB Associates (United Kingdom)
Cellular concrete provides structure, insulation, and fire and mold-resistance. Cellular concrete products include blocks, wall panels, floor and roof panels, and lintels. It also provides a low-density fill material used in geotechnical applications.
The infrastructure sector accounts for the largest market share of the market and this trend is projected to continue during the forecast period. This segment is also expected to grow at the fastest rate during the forecast period. The increase in development in the construction industry and eco- friendly building material is expected to boost the growth of the infrastructure sector. The residential sector is forecast to be the second-largest segment in the market in the coming years.
The rising demand for lightweight building materials across the world is expected to drive the market. The road sub-bases segment will see the highest CAGR from 2015 to 2020, followed by building materials and concrete pipes.
The European region is expected to account for the largest share in the cellular concrete market from 2015 to 2020. Asia-Pacific is projected to be the fastest-growing region for the market during the forecast period. Countries such as China and India are transforming their economies from being agriculture-based to manufacturing and other industry-based economies. Increasing urbanised population in China and India and growth in disposable income are driving the cellular concrete market in Asia-Pacific.
