Abstract

The increase in the cost of extracting natural aggregates, the destruction of nature through the consumption of natural resources, and the increase in construction waste have led to an increase in studies being conducted today on the use of "recycled concrete aggregates" for concrete production. Concrete with recycled aggregates is an alternative to the use of natural aggregates in concrete. In this study, a database of 27 items was created to study the parameters that affect concrete produced using recycled concrete aggregates in different proportions. Firstly, physical properties of recycled concrete aggregates such as abrasion value, density, water absorption capacity were investigated in the database. In the second stage, the factors affecting the slump, unit volume weight and strength of concretes produced with RCA were evaluated. As a result, it was found that the increase in the density of the recycled aggregate resulted in a decrease in abrasion values, while the unit volume weight and strength of the concrete increased. It was also found that the recycled aggregates had no effect on the slump of the concrete, and that the unit volume weight and strength of the concrete decreased as the amount of aggregate used increased.
