Repairing reinforced concrete slabs by composite materials

This paper describes the results of the testing of reinforced concrete slabs to the comprehension and control of the phenomenon of transmission of effort and reinforcement, by composite materials, of reinforced concrete slabs subjected to punching. The purpose of this study is the experimental analysis of reinforced concrete slabs that are control and reinforced (repaired) by composite materials [carbon fiber reinforced polymer (CFRP)] subjected to punching after degradation at various levels of load. The experimental results obtained show the strong success of the reinforcement by composite materials with respect to the increase in the failure load on the one hand and prevention of the propagation of cracks on the other hand.
