Abstract: Flyash, that is a major problem of disposal in India, is a residue that results from the combustion of ground or powdered coal. Its utilization in concrete as partial replacement of cement is gaining importance day by day. This study discusses characteristics of Fly ash as resulted from X-ray diffraction process. The study shows how it can be utilized in an efficient manner. Flyash pellets (made by providing thermal

heating at 800°C), a new generation solution. This pellet can be used as a replacement of coarse aggregate in the concrete mixture. This will reduce the self weight of concrete and can also reduce the building cost upto 5-10% than the cost by using normal aggregate.

Keywords: Thermal Conductivity, Flyash pellets, XRD, Domains.
