Eco-Friendly Goepolymer Concrete Blocks

CSIR-SERC has developed ambient temperature cured concrete blocks using geopolymer technology. These blocks are of different types - building blocks, paver blocks, hollow blocks and lightweight blocks. This technology offers a speedy, cost-effective and environment-friendly alternative to conventional Portland cement based blocks. The production of GPC blocks lead to a scientific, systematic and eco-friendly utilization of industrial wastes.

Bricks and blocks are important units for construction of civil infrastructure. The production of Geopolymer concrete (GPC) blocks lead to a scientific, systematic and eco-friendly utilization of industrial wastes. The new eco-friendly blocks will lead to a drastic reduction in the carbon footprint, embodied energy. Due to faster rate of development of strength at early ages, faster rate of construction and overall saving in life cycle cost. GPC building block technology offers a speedier and cost effective environmentally sound alternative to conventional walling materials. It can be easily adapted to suit special needs of users by modifying design parameters and is a highly profitable business for micro and small scale building material producers and construction companies. It can be extensively used, buildings, landscaping, in container yards, foot paths, parking lots, etc. The global geopolymer market is expected to register an impressive growth in the forthcoming years. The rising number of applications of geopolymer and the growing demand for geopolymer across diverse industries are the key factors expected to encourage the growth of the global polymer market in the next few years.

The technology has been already transferred to:
