Experimental Research and Simulation Analysis of Self-Repair of Cracks in Concrete Beams

Abstract:

An efficient way to repair the damage of concrete is to enable the concrete adapt to the surrounding environment actively and have self-repair capabilities. In this paper, a type of concrete beam with embedded glass fibers filled with adhesive capable of crack self-repair was investigated. The capacity of self-repair cracks in concrete beams was verified by bending tests, and the influence of the layout of glass fibers on crack self-repair was studied. Test results show that the stiffness of concrete beams increases after crack repair. The glass fibers can be arranged according to the average crack spacing of reinforced concrete beams. In addition, the influence of the levels of crack repair on properties of concrete beams was analyzed with the finite element analysis software ANSYS.
