Abstract

In this research, the effect of recycled aggregates obtained from the demolition of the old building on the preparation of concrete mixtures has been studied. The purpose of this study was to determine flexural behavior, flexural strength in reinforced concrete beams made of recycled aggregate. In the production of samples, recycled aggregates are used with 0%, 50% and 100% natural aggregates, respectively. The samples were tested for static quadrilateral bending and tested after 28 days of experiment. Therefore, by examining the results of laboratory studies, the flexural behavior of RC beams with the expansion of the recycling has been investigated. In addition, the results are compared with the relationships provided by ACI318, CSA and EuroCode2. The results obtained from this review show that by adding the ratio to the recycled aggregate substitute, the amount of net bending size at the criterial level increases and, with the expansion of the crack extending to the place of loading, the load is released flexibly. In addition, the use of 100% recycled aggregate increases the shape and flexural strength of RC concrete beams.
