Abstract:
The flexural impact behaviors of synthetic macro-fibers reinforced concrete were measured by using a newly designed drop weight flexural impact machine, synthetic macro-fibers reinforced concrete included the modified polypropylene fiber, Barchip fiber, Forta fiber and Baqi fiber, and compared with that of steel fiber reinforced concrete performance. The distribution regularity of the impact numbers was analyzed by the theory of two-parameter Weibull distribution; meanwhile, the impact numbers equations were regressed for various failure probabilities. The results indicate that impact numbers of synthetic macro-fiber reinforced concrete can be modeled well by the theory of Weibull distribution; synthetic macro-fiber can improve the flexural impactbehaviors of concrete significantly.
