摘要:
采用自制的落锤抗弯冲击试验装置,研究了改性聚丙烯、Barchip、Forta、巴奇粗合成纤维混凝土的抗弯冲击性能,并与钢纤维混凝土进行了对比。利用双参数Weibull分布理论分析了冲击次数的分布规律,回归得到了不同失效概率下的冲击次数方程。结果表明:Weibull分布理论较好地描述了粗合成纤维混凝土冲击次数的分布特征; 粗合成纤维能够显著改善混凝土的抗弯冲击性能。
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.
