  • Indian Brick Sector� Construction sector growth rate 10%, imp.contributor

    to GDP

    � Clay fired bricks –most popular building material

    � National Scenario� More than 140 billion bricks/year� Consumes more than 350 million tonnes of soil

    � Punjab & Haryana Status� 5000 brick kilns� Around 24 billion bricks� 90 million tonnes soil

  • Indian Construction Sector

    � Construction technology has changed� Most of the buildings are multi-storeyed frame

    structure.� Bricks used as fillers (non-load bearing)� Air-conditioning requirement has increased � Initiative by Government (ECBC), promotion of

    alternative building materials such as flyash bricks, Fal-G bricks etc.

    � Still clay fired solid bricks are most preferred.

  • CLAY BRICK PRODUCTION-INTERNATIONAL SCENARIO

    �In the last 60 years, no. of factors have resulted in radical changes in the European brick industry.

    �Nowadays clay brick production process with mechanized and automatic process, fully automated to get the best quality products out of the process.

    �The modern production line produce bricks of different shapes and colors.

  • BRICK MAKING IN INDIA

    In contrast to this, the situation in India, in terms of both brick making technology and the organization of the work, showed no major changes in recent decades. - Emphasis on production, irrespective of quality- Over exploitation of top soil

  • �������������

    • UNDP-GEF has launched a project on “Energy Efficiency Improvements in Indian Brick Industry”, with the focus to promote and establish the use of Resource Efficient Bricks like perforated bricks, hollow bricks, flyash bricks etc.

    • Punjab State Council for Science & Technology is the Local Resource Centre for the States of Punjab & Haryana.
