Geo-polymer concrete (GPC) is such a new class and in the present study, to produce the geo-polymer concrete the Portland cement is fully replaced with GGBFS (Ground granulated blast furnace slag), VFP (vitrified fine powder) and alkaline liquids are used for the binding of materials. It posses the advantage of rapid strength gain, without water curing, good mechanical properties and durability properties and are eco-friendly and sustainable alternative to Portland based concrete. It the construction industry mainly the production of Portland cement causes the emission of air pollution which results in environment pollution. This paper presents the details of the studies carried out on development of strength for various grades of geopolymer concrete with varying replacement GGBFS and VFP. The alkaline liquids used in this study for the geopolymerization are sodium hydroxide (NAOH) and sodium silicate (Na2SiO3). Molarities of sodium hydroxide solution (14M) are taken to prepare different mixtures. The test specimens were 150 x 150 x 150 mm cubes, 150 x 300mm cylinders prepared with oven and ambient temperature curing conditions. The geopolymer concrete specimens are tested for their compressive strength at the age of 3,7 and 28 days. GPC mix formulations with compressive strength ranging from 10 to 80 MPa have been developed. Experimental investigations have been carried out on workability, the various mechanical properties of GPC. The test results indicate that the combination of Vitrified fine powder (VFP) and ground granulated furnace slag (GGBFS) can be used for development of geopolymer concrete.
