Development of Self Compacting Geo Polymer Hybrid Fiber-Reinforced Concrete Using Highly Potential Sustainable Materials

Hybrid concrete (Self-Compacting plus Geo Polymer concrete) with Hybrid Fibers is a widely developing concrete in the construction industry that is eco-friendly and sustainable. These materials act as binders and reduce the emission of CO2 from the construction industry. Fly Ash is a by-product obtained from a thermal power plant which has more alumina-silicate content, where fly ash is completely replaced by cement which is an alternative binder to the concrete. The fly ash is replaced by 10% with GGBS and Metakaolin which enhances the pozzolanic reaction and forms Geo polymerization. The addition of SCGPC with the hybrid fiber, that is, a combination of two fibers, the total amount of fibers is 1.5% of the powder content which represents the Self Compacting Geo Polymer Hybrid Fiber Reinforced Concrete (SCGPHFC). To evaluate the flow and strength properties of the SCGPHFC. The mix SCGPHFC5, that is, 0.75% of steel and PVA fiber showed the greatest improvement in all the tests conducted among all the mixes. The results for the concrete mix SCGPHFC 5 showed high strength values compared to the other mixes of SCGPHFC.
