Flexural Behaviour of Steel Fibre Reinforced Geopolymer Concrete
Concrete is the most used construction material from ancient days. It was expected that the production of cement would be increased from about from 1.5 billion tons in 1995 to 2.2 billion tons in 2020. But 2018 china using 2.37 billion tons individually. India is the second largest producer of cement in the world. Cement industry is expected to reach 550 – 600 million tons per annum at 2025. The cement production contributes nearly 8 of worlds global warming due to emission of greenhouse gases, such as CO2, to the atmosphere. Hence, it is essential to find a substitute material for cement. The technology geopolymer concrete found as alternative for this problem. In this present research, cement is replaced with Fly Ash and GGBS in different percentages with steel fibers. The studies show that the load carrying capacity of most of the gpc mix was in the most cases more than that of conventional ordinary Portland cement concrete mix. The fresh and hardened properties of geopolymer concrete were found with and without steel fiber. The mechanical characteristics of all the examined mixes are to be enhanced by the GGBS content, in both plain and steel fibre reinforced geopolymer concrete. A comparative analysis has been carried out for normal conventional concrete to that of the steel fibre reinforced geopolymer concrete under ambient curing in relation to compressive, split tensile, flexural strengths. As the fibre content generally increases compressive, split tensile and flexural strengths are proportionally increased.
