Determination of Some Properties of Fly Ash with Lime and Cement

Panda, Debakanta and Kumar , Amit (2014) Determination of Some Properties of Fly Ash with Lime and Cement. BTech thesis.



In India the present generation of fly ash is around 150 million tonnes and utilization percentage is 55-60%. A lot of efforts and innovations are required to achieve 100% utilization. Fly ash in itself has little strength. But it gains strength in presence of additives. This investigation is an attempt to develop fly ash composite materials with lime and cement with respect to enhanced compressive strengths, tensile strengths, and shear parameters so as to evaluate the potential in geotechnical usage. Calcium carrying material as cement and lime were used as additives. Varying proportions of fly ash, lime and cement were mixed to develop the composite materials. Optimum moisture content, maximum dry density, unconfined compressive strength, Brazilian tensile strength, and shear strength parameters were determined at varying curing period. Fly ash with 5% lime was found to exhibit maximum compressive and tensile strength.
