Abstract

Abstract: Geopolymer is being evaluated as a possible alternative to traditional concrete in the building sector. With the inclusion of Polypropylene Fibres, Geopolymer binding material is created in this study. Various durability tests as well as the influence of Polypropylene Fibre on concrete were conducted. The cubes' resilience was observed and investigated after being immersed in several hostile solutions. The resulting concrete has a high compressive strength as well as a long lifespan. For all mix proportions, the quality of Geo-polymer Concrete is excellent, especially for polypropylene fibre additions up to 0.6 percent. The drying shrinkage of Geopolymer concrete can be minimized by adding Polypropylene Fibre to the cement. Polypropylene fibre improves the performance of Geopolymer Concrete by resisting the chloride penetration and so increasing its longevity. The results also showed that inserting Polypropylene fibre into FRGP concrete improves resistance to high temperature exposure. The sulphate attack results show that loss in Compressive Strength decreases with increasing Polypropylene Fibre addition up to a limit of 0.6 percent.
