Growth of Industries and Urbanization have some negative impacts on our
society and environment due the by-product of industries. Fly ash(FA),
bottom ash(BA) and granulated blast furnace slag (GBFS), effulent
treatment plant sludge (ETP sludge) are industrial wastes from thermal
power plant and steel industries respectively. These generated wastes
creates a loss of materials, energy and impose economic & environmental
costs on society for its collection, treatment and disposal. These
by-products create environmental problems like air pollution, water
pollution and land degradation etc. Utilization of these waste as a
building materials products like brick and concrete by geopolymerization
techniques have been attempted.
