The high costs and environmental damage in conventional concrete production have led researchers to search for alternative materials. The aim of the studies carried out in this context is to improve the material mechanical properties of concrete and to progressive economical products. When the existing literature is examined; the changing material mechanical properties of concrete have been examined by adding materials such as fly ash, blast furnace slag, waste rubber, steel wire and plastic fiber in different volumetric ratios to concrete or by using light, sustainable and economical materials such as natural perlite instead of conventional aggregate in the concrete ingredient. The bond-reinforcement slip relationship between reinforcement bar and concrete depends on many factors such as concrete compression level, bar diameter, embedment depth, and concrete void structure. In this study; it was aimed to investigate the effect of concrete compression level, concrete cover and perlite usage parameters on the bond-reinforcement slip relationship between reinforcement bar and concrete by producing a total of 24 cube samples with 20 MPa and 40 MPa compressive strength and 2.0 mm and 4.0 mm concrete cover using conventional aggregate and natural perlite aggregate. From the research to be conducted; it is expected that the bond strength of conventional concrete and natural perlite concrete will be improved by increasing the concrete compressive strength and concrete cover parameters.
