EXPERIMENTAL STUDIES ON GEOPOLYMER CONCRETE USING GGBFS AND MARBLE POWDER
Keywords:Geopolymer Concrete, GGBFS, Marble Powder, Ambient Curing, Molarity, Mechanical Strengths.
Geopolymer concrete is an innovative construction material which has been made by the chemical action of inorganic molecules. It is commonly used construction material for replacement of the plain cement concrete. Geopolymer concrete are made with 0% amount of ordinary portland cement. In this experimental study are done for checking the mechanical strength properties of geopolymer concrete using GGBFS with different % replacement of Fly Ash (20%, 40%, 60%, 80%) and Marble Powder with different % replacement of Fine Aggregate (20%, 40%, 60%, 80%) on geopolymer concrete. In this project, the mix design is carried out for 12M concentration of sodium hydroxide. Alkaline activator solution ratio of 2.5 and alkaline liquid to fly ash ratio 0.56 is selected and conduct constant for this investigation. The specimen of size 150x150x150mm cubes, 150x300mm cylinders and 500x100x100mm beam were casted and the specimens of geo-polymer concrete are cured at ambient temperature for 3day 7days and 28days. The experiment are to be carried for the mechanical strength like a compressive strength, split tensile strength, flexural strength test on the concrete specimens and the test results are tabulated.
