EXPERIMENTAL INVESTIGATION ON COMPRESSIVE STRENGTH AND DURABILITY PROPERTIES OFGEOPOLYMER CONCRETE INCORPORATING WITH NANO SILICA

Global warming has emerged today as life-threatening issue for the world. As concrete is one the most consumed material after water on the earth for infrastructure & construction industries, a commendable contribution cam be made by optimizing the use of cement and natural resources in concrete manufacturing. Geopolymer concrete is one of the major developments in recent years leading to utilization of fly ash in large quantities and thus reducing cement consumption and ultimately reducing emission of CO 2 in order of one tonne per a tonne of cement. Mechanical &Durability properties of concrete structure is another important parameter affecting the sustainability of concrete technology in addition t o minimizing use of virgin material. Experimental investigation has been taken up on low calcium fly ash based Geopolymer concrete having three different molar concentration of activator liquids along with different percentage of Nano silica addition.
