【 摘 要 】
The mechanical properties of a new type of hybrid fiber reinforced concrete (HFRC) which was reinforced by the steel fiber and the ultra-high molecular weight polyethylene (UHMWPE) fiber were researched. The effects of the fiber hybrid ratio on the strength and cracking-resistance properties of concrete were studied through the split-tensile and the cubic-compression tests on 16 types of HFRC. The result shows that the hybrid of the steel fiber and UHMWPE fiber can play a multi-layered role in crack-resistance properties of concrete. The strengths of HFRC is further increased when the UHMWPE fiber are mixed on the basis of the steel fiber. When the fiber volume content of UHMWPE is extra added by 0.3%, the tensile strength increases by 13.64%, 49.49% or 8.08%, and the compressive strength increases by 13.51%, 15.49% or 14.57% compared with the single steel fiber reinforced concrete as the fiber content is 0.5%, 1.0% or 1.5%. The UHMWPE fiber has more obvious effects on material strength compared with polypropylene fiber when it is mixed with the steel fiber reinforced concrete.【 预 览 】
