PERFORMANCE OF GEO POLYMER CONCRETE WITH M-SAND

The cement production is not only highly energy-intensive, but also consumes significant amount of natural resources. On the other hand, already huge volumes of GGBS are generated around the world; most of the GGBS is not effectively used, and a large part of it is disposed in landfills. Both the above issues are addressed in this work. Geopolymer concrete is produced by mixing GGBS (Slag) and Alkaline liquids.The grade chosen for the investigation is M-30 grade. Molarity is grams of solute to be dissolved in one litre of solution. It represents the concentration of solution. The mixes are designed for molarities of 16, 17 and 18 respectively. The alkaline solution used for present study is the combination of sodium silicate and sodium hydroxide solution with the ratio of 2.5. The test specimens consists of cubes (150x150x150) mm, cylinders (150x300) mm and the specimens will be ambient cured. The various tests will be conducted on specimens are compressive strength and split tensile strength. The tests are conducted at 7 and 28 days after the specimens are prepared.
