The current investigation into the manufacture of Geopolymer concrete using industrial by products such as abundant worldwide availability of fly ash provides the potential to use this by- product of burning coal as a replacement for concrete production by OPC.
Details about the Experimental System with checking of the fundamentalproperties of both geop olymer concrete and ordinary Portland cement concrete.The basic properties include the workabi lity of hardened fresh concrete, compressive and tensile strength and their resistance to acid atta ck when immersed in 10 percent solution of sulphuric acid in the laboratory for different curing age.
