摘 要：In recent decades,the industrialization and urbanization are the two phenomena that are going unabated all over the *** from the need for these phenomena,one has to look into their negative impacts on the global environment and social *** important ill effect of these global processes has been the generation of large quantities of industrial ***,the problems related with their safe management and disposal has become a major challenge to environmentalists and *** related problem is the pressure on land,materials and resources to support the developmental activities,including *** thermal power plants generate significantly large quantities of solid byproduct namely *** present,the disposal of generated flyash is by either wet disposal or dry *** is also extensively used for a variety of construction ***,there is a need to address the problems encountered during the disposal or reuse flyash in construction *** 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 *** 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 *** scope of this paper is limited to flyash from thermal power *** ash and slag as well as flyash generated from other industrial sources are beyond the scope of this paper.
