| Abstract: |
In India, fly ash generation reached to 130 million tonne per year (mtpy) during 2006-07, leaving about 70 mtpy unutilised posing serious disposal problem. A substantial part of fly ash is disposed off in the form of slurry, called as pond ash occupying hundreds of hectors of land. Environmentally compatible disposal through utilisation of waste materials by appropriate technologies is of increasing importance and imposes interesting technical challenges. There is an extreme scarcity of natural sand to be used as fine aggregate in concrete. Hence it indicates urgent need of effective utilisation of pond ash and crusher stone waste and conserves the natural resources. This paper addresses the use of pond ash and crusher stone waste as fine aggregate by replacing natural sand with pond ash in 25%, 50% and 75% of the total fine aggregate with crusher stone waste. The feasibility of pond ash with crusher stone waste is studied by performing compressive strength, and also correlating it by performing NDT tests. |
