Experimental study of shear stresses of solid and hollow concrete beams made with Waste Tire rubber

Numerous studies have suggested using alternative materials in concrete; waste tire rubber is one such item which has drawn a lot of interest. Furthermore, tire landfilling-one of the biggest ecological issues facing the planet in the near future can be avoided by reusing and recycling waste tire rubber. The rubber crumb waste is added to concrete mixtures at those percentage values of 0%, and 15% as substitute by coarse aggregate weight. This research investigates the Shear and Flexural Behaviour and Action of Reinforced Solid Recycled Rubber Concrete Beams (SRRCB) and Reinforced Hollow Recycled Rubber Concrete Beams (HRRCB) composed of Tire Rubber Crumb and Granular Waste under a two-point load. The flexural behavior of HRRCB and SRRCB was assessed and calculated in the presented work using a four-point bending test on six reinforced concrete solid and hollow beams. Beams prepared with 230 mm height, 1000 mm length, and 120 mm are described in this study. Rubber aggregate influence as partial substitute for the fine aggregate in the concrete was investigated by looking at the beam response. To assess test units' failure pattern, the experimental beams have been compared to normal-weight concrete. Comparing a beam with a 15% rubber aggregate replacement ratio to one with conventional aggregate concrete, the load behavior was identical. According to the findings, hollow opening had impact on HRRCB's Ultimate Load Level Capacity and Deflection. In order to lower the overall cost and weight of HLC beams, greater customization of the beam's construction and design features is possible. Due to the fact that their response is identical to that of beams constructed with conventional concrete, ultimate load of beams that are produced with 15% recycled rubber aggregate concrete might be complimented and utilized. Findings have played a role in the understanding of the mechanical performance and failure mechanisms of these beams, offering valuable information about potential applications of the recycled Tire Rubber aggregates in structural engineering. Based on this premise, the study was undertaken to investigate shear behaviour of the hollow and solid concrete beams incorporating recycled Tire Rubber aggregates, aligning with ongoing efforts of sustainability in the construction.
