According to the general perception, the use of recycled aggregate in concrete reduces the mechanical properties of concrete. In this paper, the properties of high strength recycled aggregate concrete is evaluated by three ways, such as the addition of glass fiber and Polyvinyl Alcohol fiber, and partial replacement of cement with fly ash and granulated furnace slag and the addition of superplasticizer. Moreover, the size of the fiber used is experiments is 10mm and 20mm. Both of these fibers are used individually as well as in combination with a different ratio of 0.1%, 0.15%, and 2%. Consequently, the percentage replacement of natural aggregate with recycled aggregate is 0%, 50%, and 100%. The experiment results show that the adhered mortar on recycled aggregates, and the varying amount of recycled aggregate significantly affects the strength of concrete. The use of glass fiber and polyvinyl alcohol fiber increases the splitting tensile strength and flexural strength. Additionally, the use of mineral admixtures and fiber increases the bond strength, which significantly improves the strength of concrete.
