  • Abstract:
  • 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). Different molarities of sodium hydroxide solution 10M is taken to prepare different mixes. And the compressive strength is calculated for each of the mix. The geo-polymer concrete specimens are tested for their compressive strength at the age of 3 and 7 days. The result shows that there is significant increase in the strength of oven cured specimens after 3 days of oven curing and the strength of geo-polymer concrete is increasing with the increase of the molarity of sodium hydroxide. The objective of this project is to study the effect of Metakaolin (MK) and ground granulated blast furnace slag (GGBS) on the mechanical properties of geopolymer oncrete (GPC) at different replacement levels (MK80-GGBS20, MK70-GGBS30, MK60-GGBS40). Sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) solution have been used as alkaline activators. In the present investigation, it is proposed to study the mechanical properties viz. compressive strength, split tensile strength of Metakaolin and GGBS based geopolymer concrete. These properties have been determined at different curing periods like 3, 7, 28, days and at ambient room temperature.
