Title of the Innovation: Geopolymer Blocks Technology

Brief About Innovation

Introduction: 

Geopolymer concretes (GPCs) are new class of building materials that have emerged as an alternative to the existing concretes and possess the potential to revolutionize the building construction industry. The Geo-polymer concrete block technology is a low cost and eco-friendly technology which can be easily commercialized by SMEs. The technology has been already demonstrated in pilot scale. The technology offers high early strength, Portland cement free binder with better life-cycle cost when compared to Portland cement-based concrete.

About the Technology: 

The production of GPC blocks lead to a scientific, systematic and eco-friendly utilization of industrial wastes. This novel technology developed offers 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. 

Level/Scale of Development: TRL - 8

Salient Features and Advantages:

• A novel technology for producing eco-friendly geopolymer concrete (GPC) blocks with zero Portland cement.
• Low carbon footprint.
• Complete replacement of Portland cement in concrete with industrial byproducts such as fly ash and ground granulated blast furnace slag.
• Zero water for curing (ambient air curing).
• Lower embodied energy.
• High early age mechanical strength and high durability properties.
• Robust durability properties.
• Environment-friendly and sustainable

Applications:

• Applications - In buildings, landscaping, container yards, foot paths, parking lots, pavements, etc.
• Problem addressed - Global warming, waste utilization, effective disposal of industrial waste, water consumption, environmental ecology.
• Alternate to conventional Portland cement-based blocks.
