THE INDUSTRY

The construction industry in India is an important indicator of growth and development as it is second largest industry of the country after agriculture and creates investment opportunities and increases production capacity across various related sectors. With a share of around 8.2 per cent, the construction industry has contributed an estimated 670,778 crore (at current prices) to national GDP at factor cost in 2011-12.

The construction industry contributes to about 10% of the Gross Domestic Product (GDP), registering an annual growth of about 9%.

OPPORTUNITY/MARKET ASSESSMENT

The brick sector in India, although unorganized, is tremendous in size and spread. India is the second largest brick producer (China dominates with 54 % share) in the world. It is continuously expanding on account of a rapid increase in demand for bricks in infrastructure and housing industries. In order to meet this demand, over 150,000 brick units provide direct employment to more than 8 million workers.

But with growing environmental consciousness at all levels of society, the pollution caused by the brick industry is under the scrutiny of environmentalists and the government. Therefore, the optimal solution is to encourage setting up of eco-building material enterprises.

The demand of bricks is increasing over the years so much so that Bihar state alone needs over 7500 million bricks over the next five years just to meet the rural housing gap of 1.1 million dwellings per year.

TECHNOLOGY

Fly-Ash Technology
Fly ash brick technology is a process of converting industrial waste materials into quality building materials. At present, the technology is well established in converting thermal power plant waste into quality bricks.

Fly ash technology uses dry ash (fly ash collected from ESP or silos of thermal power plants); filler materials (usually coarse sand or stone crusher dust); and additives (lime, gypsum or cement). The strength of the bricks can be engineered by varying compositions. Equipment used can be manual or mechanized. Mechanized machines deploy hydraulic compaction to produce a variety of bricks and can be operated through electric or diesel power.

Eco-Concrete Technology
Eco Concrete Technologies exemplifies highly efficient use of energy intensive materials such as cement and steel. As a result, the well-designed building products and components from the Eco Concrete Technologies are cost effective, high quality and locally produced.
