EXPERIMENTAL INVESTIGATION ON GEO POLYMER CONCRETE

Abstract

Based on the results obtained from this study, the following Conclusions seems to be valid. The increase in percentage replacement of Fly Ash with Metakaoline from 0% to 10.00% causes increase in Slump value up to 5% and beyond that slump is decreased. This shows workability is reducing as percentage of Metakaoline increased beyond 5%. Hence, 5% replacement of Fly ash with Metakaoline is suitable from workability point of view. The increase in percentage replacement of Fly ash with Metakaoline from 0% to 5% causes increase in compressive strength of concrete from 17.6MPa to 22.6MPa. Further increase in percentage replacement of Fly ash with Metakaoline from 5% to 10% causes decrease in the compressive strength from 22.6MPa to 18.7MPa. Hence, 5.00% replacement of Fly Ash with Metakaoline is advisable from compressive strength point of view .The increase in percentage replacement of Fly ash with Metakaoline from 0% to 5% causes increase in Split Tensile strength of concrete from 3.72MPa to 4.68MPa. Further increase in percentage replacement of Fly ash with Metakaoline from 5% to 10% causes decrease in the split Tensile strength from 4.68MPa to 3.94MPa. Hence, 5.00% replacement of Fly Ash with Metakaoline is advisable from Split Tensile strength point of view. The increase in percentage replacement of Fly ash with Metakaoline from 0% to 5% causes increase in flexural strength of concrete from 3.0 MPa to 3.36 MPa. Further increase in percentage replacement of Fly ash with Metakaoline from 5% to 10% causes decrease in the flexural strength from 3.36MPa to 3.2MPa. Hence, 5.00% replacement of Fly Ash with Metakaoline is advisable from flexural strength point of view. Finally, it can conclude Keeping in view of the workability, compressive strength, Split Tensile Strength and flexural strength in mind, 5% replacement of Fly ash with Metakaoline is recommended for use in GEO POLYMER CONCRETE (GPC).
This paper presents test data on fly ash-based geopolymer concrete. The paper covers the material and the mixture proportions, the manufacturing process, the fresh and hardened state characteristics, the influence of various parameters on the fresh and hardened state concrete, the utilization of the material in structural members, and the Short -term behavior .
