| Abstract: | In order to analyzes the influence of the polypropylene fiber recycled concrete beam crack resistance and the ultimate bearing capaci-ty,the paper undertakes the flexural test and comparative analysis of the ten beam components,indicates by the result that the polyprophlene fi-ber can promote the concrete crack resistance performance obviously,concludes the discrepancy between the ultimate flexural bearing capacity of the components and the factual measured value is less than 2% by adopting the regular calculation,and proves the regular formula is feasible. |
