Development of geopolymer from pond ash-thermal power plant waste : Novel constructional materials for civil engineers

Demonstrates how to utilize fly ash/pond ash (waste materials from thermal power plants) to produce a novel material called 'Geopolymer' (GP). Red mud, slags, etc., are mixed with fly ash to produce GP with enhanced strength. As shown in a few European countries, GP can replace cement, and some permanent structures constructed with GP are now appearing in a few advanced countries. GP, and geopolymer concrete, is considered suitable for the construction of roads, buildings, etc., and will eventually, fully or partially, replace cement.
