Dear Sparsh,
Currently due to over generation of fly ash from thermal power plants, instead of dumping in landfill .... researchers have found its use in making bricks. Fly ash bricks are light in weight compared to conventional bricks and have more strength. These bricks are prepared as per Indian Standard IS: 12894- 2002. It is gaining much value and several practical applications and models have also been under construction.
I am attaching few links for your information:

you can collect more information from internet.

Lanjigarh Alumina refinery of Vedanta has become the first company in the world to develop Cement Free Green Concrete by using Fly Ash only. The concrete is named as Cold Setting Geo-Polymer Concrete due to its properties of fast setting in ambient conditions. Speaking on the occasion Dr Mukesh Kumar , President and COO of Lanjigarh Alumina Refinery informed that they have developed a Zero Waste Model around 3 years back and since than they are working on numbers of projects related with Waste Utilization to ensure Optimum Utilization of Natural resources. This new technology has been developed in association with CSIR laboratory IMMT, Bhubaneshwar and inhouse research.The details are enclosed about CSIR-IMMT flyash bricks.
