Evaluation of shear behavior of prepared recycled concrete aggregate concrete deep beam

Abstract

In this article, the shear behavior of a deep beam made of Recycled Aggregate Concrete (RAC) was analyzed. Rapid urbanization has presented a massive new activity that is necessary to meet the needs of the influx of people. Developments of all types, from housing to infrastructure, necessitate considerable input from both natural and monetary resources. The purpose of this study is to compare the strength and loading capacity of RAC to that of Naturally Aggregate Concrete (NAC). The samples were evaluated at a controlled deformation rate of 2mm/minute in the "Material Testing Laboratory of the Department of Civil Engineering," where this investigation was conducted. The researcher has chosen two different sizes of coarse totals to use throughout this study: those measuring 5mm to 15mm (60.2%) and those measuring 15mm to 25mm (40.3%). In support of her claims, the researcher presents a variety of charts and datasets in the following research. There is an overall drop in strength in the recycled aggregate concrete samples. The load-deflection curves and the techniques are depicted by which the specimens failed. Shear required beams' experimental data and predicted values. This study reveals that compared to natural aggregate concrete, recycled aggregate concrete has weaker compressive, flexural, and breaking tensile strengths. The maximum load-bearing strength of longitudinally supported beams built of "recycled and natural aggregate concrete" is also not significantly different.
