Strength of Hybrid Fiber Reinforced High-Performance Concrete
The paper presents an experimental study on the splitting tensile strength and compressive strength of hybrid fiber reinforced high-performance concrete (HFRHPC). In the light of the state standards and test methods, splitting tensile strength and compressive strength of 10 different groups of hybrid fiber (containing steel fiber and polypropylene fiber) reinforced concrete specimens are tested. The results show that adding a reasonable volume of hybrid fibers to high-performance concrete, the splitting tensile strength increases by 10％~40％ while the ratio between splitting tensile strength and compressive strength for HFRHPC increases to 1/18~ 1/16. When adding 0.8％ steel fiber and 0.11％ polypropylene fiber, the optimal result of hybrid fiber reinforced high-performance concrete occurs, with the ratio between splitting tensile strength and compressive strength increasing to more than 1/16. Thus, adding reasonable steel fiber and polypropylene fiber into high-performance concrete is helpful to increase splitting tensile strength, as well as the ratio between splitting tensile strength and compressive strength.
