“…The experimental examination of RAC beams demonstrated that altering the amount of RCA in RAC had no effect on structural behavior [22,23]. The globe moves toward sustainable sources, and the research toward innovation with new technologies should be transparent as well as acceptable at large [24,25]. The wastewater treatment plant and sewer structures, such as domestic sewage, industrial sewage, or storm water carrying concrete structures, are exposed to wastewater, and the industrial structures near to boilers in the textile industry as well as nuclear power plants are exposed to heat.…”

In this study, natural coarse aggregates were replaced with coarse recycled concrete aggregate (RCA) in 0 %, 50 %, and 100 % extracted from construction and demolition wastes. Their recycling could lead to a greener resolution for preserving the environment and paving the way for sustainability through solid waste management. The compressive strength of 0 %, 50 % and 100 % RCA at 365 days was reduced by 3.97 %, 4.88 %, 6.81 %, respectively, compared to the compressive strength at 28 days. Tensile strength at 365 days was reduced by 4.31 %, 6.50 % and 9.83 % compared to tensile strength at 28 days. There was no discernible effect of water type on the strength properties of concrete. Compared to other combinations, 100 % RCA concrete experiences a greater percentage of weight loss owing to evaporation of free water. When temperature was elevated, the concrete matrix expands and deep cracks were observed on the concrete surface. The overall performance of recycled aggregate concrete was not much influenced by the use of such aggregates, so these findings will add a new achievement to a sustainable construction through solid waste management.

“…14 INTRODUCTION 1 People's daily lives depend on energy production and consumption, so supply and demand in human societies amount of CO2 from the combustion of fossil fuels has been released in to atmosphere, of which about 72% of greenhouse gases are produced in the Middle East [4]. Therefore, replacing fossil energy with renewable energy, including solar energy, is one of the solutions to deal with energy and environmental crises [5][6][7].…”

“…Many structural engineers and researchers also studied the flexural [19], shear [20], and bond [21] performance of RAC elements, but slight work has been found on the torsion. The research work related to reducing carbon emissions mention that, the globe moves toward sustainable sources and the research toward innovation with new technologies should be transparent and acceptable at large scale [22,23]. Except the investigation by Sarsam et al [4], and Masne et al [6] no test data on the torsional behaviour of RAC beams is available in literature.…”

In the past two decade, researchers have studied the flexural, shear and bond behaviour of recycled aggregate concrete (RAC) beams. This work intends to analyze the behaviour of RAC beams under pure torsion, despite the lack of information on its behaviour under pure torsion. The coarse recycled concrete aggregates (RCA) extracted from construction and demolition (C & D) waste was used to replace natural coarse aggregates (NCA) in 0 %, 50 %, and 100 % ratio. Their recycling could help preserve the environment and promote sustainability through solid waste management. Six beams, each of size 150 x 250 x 1800 mm were prepared and tested. To detects minor deformation and to achieve the same strength through the out-of-plane direction, 250 mm inbuilt cantilever projections were provided on opposite faces of the beams at a span of 1000 mm along the longitudinal axis. The ultimate torsional capacity of tested beams was lower by 7.41 %, 8.60 % and 13.58 % than ATENA-3D (FEM) for 0 %, 50 % and 100 % RCA. The change in the replacement ratio of aggregate has a low impact on the ultimate torque and angle of twist. Based on the experimental and analytical results, it was established that the torque resistance capacity of the RAC beam was reduced as the % of RCA increased. Similar crack patterns and failure behaviour were observed in RAC and NAC beams in both studies. Therefore, it is practically possible to apply RAC in structural applications under pure torsional loading.
