Synthesis and characterization of synthetic sand by geopolymerization of industrial wastes (fly ash and GGBS) replacing the natural river sand.

The diminution of the natural sources in the form of dredging the riverbanks and blasting the mountain ranges has always dented the balance of the ecosystem which in turn results in disasters as well at times. This alarming situation accelerates the global warming, threatens the biota life in riverbanks, diminishes the ground water level, harms the aquatic life, and affects the growth of agriculture. This study is an attempt to synthesis fine aggregates from the industrial byproducts, namely, fly ash and GGBS through the process of geopolymerization.
