钢纤维混凝土在旧混凝土路面修补中的应用

On Steel Fibre Concrete Applied in Old Concrete Pavement Reparation

钢纤维混凝土是一种新型高强复合材料,具有良好的抗折、抗冲击、抗疲劳以及收缩率小、韧性好、耐磨耗能力强等特性。通过鄂尔多斯市某二级公路工程实例,介绍了钢纤维混凝土材料实际应用于旧混凝土路面修补的可行性。实践证明钢纤维混凝土不仅可改善路面的性能及使用寿命,而且还可节省工程造价。

Steel fibre concrete is a new type high-strength composite material with many features of good anti-breaking,shock resistance,anti-fatigue,small shrinking percentage,good toughness and great anti-abrasion.Taking some second highway project in Erdos,the feasibility of steel fiber concrete material applied in the old concrete pavement reparation is introduced.The practice can prove that steel fiber concrete not only can improve the performance and service life of the pavement,but also can save the project cost.
