| 摘 要： | 柔性纤维混凝土是近年来开始在中国运用的一种新的建筑材料。柔性纤维混凝土和普通混凝土相比，具有很多优良特性。本文结合道路工程对材料的具体要求和实验室的部分实验结果，介绍了不同掺量（体积比为0，0.5%，1.0%）聚丙烯纤维对不同取代量粉煤灰道路混凝土抗折强度、弯韧度指数、post-crack强度以及耐磨耗性的影响，得出了掺聚丙烯短纤维能改善高掺粉煤灰道路混凝土的路用性能，对于道路建设推广运用新材料、节约工程成本具有一定的理论和实际意义。 |
| 关 键 词： | 建筑材料；聚丙烯纤维；粉煤灰道路混凝土；抗折强度；弯韧度指数；耐磨耗性 |

| Abstract： | Recently, flexible fiber reinforced concrete has been involved in many practical fields in China as a new building material. Flexible fiber reinforced concrete has many benefits over the ordinary concrete. This paper shows field and experimental work for pavement fly ash concrete incorporating polypropylene fibers with different percentage (0, 0.5% and 1.0%) in volume. Different parameters are considered in the current work, such as flexure strength, bending toughness index, post-crack strength, as well as measuring the depression resulting from the abrasion test. The results show the adequacy of using polypropylene fibers to improve the overall performance of the road pavements. It is recommended to make use of the current results to extend the use of polypropylene fibers in road construction. It is also thought that the overall cost will be less than other means of reinforcement to obtain the same performance. |
