Examination on GGBS based Geopolymer Mortar at elevated temperatures

Abstract

In India approximately 120 million tonnes of flyash is produced every year from thermal power stations and enormous quantities of stone dust, a waste product, produced from the aggregate crusher units at the time of rubble crushing. Usage or disposal of this by-product within the framework of its economic structure becomes a challenging problem to every country because of increasing interest in conservation of energy and resources and growing concern with environmental issues. Also Land disposal becomes a serious problem due to scarcity of land. Due to this the M-sand and GGBS is used as ingredients in mortar which enhance the properties of mortar and utilization of M-sand is helpful for consumption. To study the alkaline solution of NaOH and Na2SiO3 is mixed with processed fly ash to become geopolymer mortar. This mortar cubes at different molarities and different temperature so as to increase the strength of the cubes.
