Abstract
Fly ash is generated in large quantities as a byproduct of burning coal. Thermal power plants are the major sources of ash generation. Fly ash is disposed in the form of slurry in the ash ponds within the plant area, called coal combustion residue or pond ash. When fly ash is mixed with water, afterwards it gets hardened and forms high strength and low permeability material. Fly ash produced thus possesses both ceramic and pozzolanic properties. The power requirements of the country are rapidly increasing in pace with in industrial developments. Nearly, 73% of India‟s total installed power generation capacity is thermal of which coal based generation are nearly 90% (by diesel, wind, gas and steam adding about 10%). The inherent strength of the compacted pond ash mass reduces considerably due to saturation. In this context to improve and retain the strength of compacted pond ash, cementing agents like cement or lime may be very much beneficial. The stress-strain behavior of compacted pond ash mass can be modified by inclusion of fibre reinforcements. Fibre reinforcements also improve the strength characteristics of the mass. This paper presents the details of the pond ashes, the experiments carried out to characterize them when mixed with fiber and the results and discussions.
