Disposal and Management of Flyash

An attempt has been made in this present paper to highlight on the pollution hazards due to the disposal of flyash into the environment and its utilization in civil engineering activities, their possible remedies and the research and development needed to address the above stated issues. The main topics covered in the present paper are flyash quantification and characterization in terms of physicochemical and mineralogical analysis and the classification of flyash; pollution problems due to flyash disposal systems, utilization of flyash in various construction activities and problems encountered during reuse and storage of flyash and its possible remedial measures. The scope of this paper is limited to flyash from thermal power plants. Bottom ash and slag as well as flyash generated from other industrial sources are beyond the scope of this paper.
