Abstract

Abstract

The effects of hybrid fiber on hi gh performance concrete properties under high temperature were studied.The exper iment applies hybrid fiber with low(polypropylene fiber)and high melting point(s teel fiber)to improve mechanical properties and bursting resistance of high perf ormance concrete,since high performance concrete easily spalls and destroys afte r being on fire.The results show that flexural strength residual rate of hybrid fiber reinforced concrete(about 15%)is higher than that of normal concrete(about 6%);compressive strength residual rate of hybrid fiber reinforced concrete(abou t 15%)is approximate to that of normal concrete(about 15%);splitting tensile str ength residual rate of hybrid fiber reinforced concrete(about 20%) is higher tha n that of normal concrete(about 10%).Hybrid fiber has significant improvement on spalling resistance of concrete,and the active mechanism of hybrid fiber improv ement on high performance concrete is also analyzed.
- hybrid fiber,
- high performance concrete,
