Many researchers have shown that it is engineering feasible to use fiber-reinforced polymer (FRP) bars instead of steel bars as the tension-affected main bars in reinforced concrete structures. However, concrete slabs strengthened with FRP bars are limited in the field of civil engineering. For example, the elastic modulus of FRP bars is low, and the ductility of the member is reduced due to the brittleness of FRP bars. To solve these problems as much as possible, scholars have adopted an idea that can use both FRP bars and steel bars in concrete members. There are still some problems with the bending behavior and durability of the proposed structural reinforcement, and further research is needed in this area. In this paper, the concrete slabs strengthened with GFRP reinforcement and reinforced mixing on the bending properties and durability of the experimental research, and some important findings are summarized.
