Research on Mechanical Properties of Steel Fiber Reinforced High Performance Recycled Concrete

Abstract:

In this paper, high-quality mineral admixtures and superplasticizer double mixing technology is used to produce high performance recycled concert (HPRC), and then steel fibers are used to modify the characteristics of HPRAC. The compressive strength, splitting tensile strength, ultimate bending load and fracture energy of HPRC with different content of steel fiber. Experiments suggest that with the increase of steel fiber content, the compressive strength doesn’t change too much, but the splitting tensile strength, ultimate bending load and facture energy increase dramatically. Therefore it can be concluded that increasing the content of steel fiber properly can improve the ductility and resistance to crack propagation of HPRC and enhance the ultimate load of HPRC bending member.
