Experimental Investigation on Spent Catalyst Based Self- Consolidating Concrete (SCC) RC Beams with Conventional and GFRP Rebars

Summary

Only water is used as much globally as concrete. 600 kilograms of carbon dioxide are released into the atmosphere during the production of one ton of cement. As a result, civil engineers are always searching for substitute materials to replace cement, the substance that is used in buildings, either whole or in part. Concrete that is ecologically friendly is made by using industrial byproducts such as fly ash, silica fume, rice husk ash, and chemical admixtures. One such endeavor that has demonstrated its applicability in a fluid form and been effective in laying concrete in buildings with crowded reinforcing without any internal or external vibration is the production of self-consolidating concrete, or SCC. The optimal dose of spent catalyst-based self-consolidating concrete (SCC) with RC beams employing conventional and GFRP rebars is the primary goal of this research. The College of Engineering’s ongoing study has shown that the ideal dose for employing wasted catalyst to partially replace cement is 9% [1]. The primary study focuses on the quantity of glass fibre reinforced polymer (GFRP) rebar needed to equal the load-carrying capability of the conventional rebar in the RC beam. For the RC beams with GFRP rebar, ACI 440.6M-08 and ACI 440.1R-15 are the design rules that are followed. There will be a comparison of GFRP and conventional rebar beams, and an evaluation of the RC beams under monotonic loading conditions. Waste material will be turned into raw materials by the development of new technologies, which will create goods with additional value. The initiative is justified from an economic, social, and environmental standpoint. The project will fulfil the fundamental needs of sustainability, safety, and serviceability as well as sustainable waste management and sustainable materials in the building sector.
