GEO POLYMER CONCRETE WITH GGBS (GROUND GRANULATED BLAST FURNACE SLAG)

The major problem the world is facing today is the environmental pollution. In the construction industry mainly the production of Portland cement will causes the emission of pollutants results in environmental pollution. We can reduce the pollution effect on environment, by increasing the usage of industrial by-products in our construction industry. Geo-polymer concrete is such a one and in the present study, to produce the geo-polymer concrete the Portland cement is fully replaced with GGBS (Ground granulated blast furnace slag) and alkaline liquids are used for the binding of materials. The alkaline liquids used in this study for the polymerization are the solutions of Sodium-hydroxide (NaOH) and sodium silicate (Na2Sio3).. This study investigates the use of GGBFS (ground granulated blast furnace slag) in 100% replacements by mass in cement. Harden concrete properties like compressive strength, Spilt tensile, flexural strength of concrete are be determined for Geoplymer concrete and Normal concrete. Finally the test results were compared from the test results, it has been observed that the geo-polymer concrete possess better result than the normal concrete.
