Waste Fiber Recycled Concrete Performance Based on Fracture Mechanics Research

Abstract:

This paper studies on the waste fiber strength test of 88 concrete beams crack , the beams section-dimension are 100mm×100mm and length 500mm. Research on recycled aggregate replacement ratio, the waste fiber length and incorporation, the crack height-ratio effect on fracture toughness of concrete. The result indicates that the waste fibers can effectively limit extension and perforation of crack of recycled aggregate, increasing the ductility of concrete, enhancing fracture properties of concrete and conducive to the improvement of fracture toughness of concrete.
