介绍了钢纤维混凝土材料在旧混凝土路面修补的情况,并在分析配比试验强度的基础上,通过某工程实例,证实钢纤维混凝土实际应用于旧混凝土路面修补工程的可行性。钢纤维混凝土是一种性能优良的新型复合材料。与普通混凝土相比,其抗拉、抗弯、抗裂及耐磨、耐冲击、耐疲劳、韧性等性能都有显著提高,它不仅可使面层减薄,缩缝间距加大,改善路面的使用性能,延长路面使用寿命,而且还可节省工程造价,缩短施工工期。
The situation of steel fiber reinforced concrete repaired on the old concrete pavement is introduced. Based on the analysis of the strength of the compounded test, an engineering example is given to verify the feasibility of applying the steel fiber concrete to the repairing of the old concrete pavement. Steel fiber reinforced concrete is a new type of composite with excellent properties. Compared with ordinary concrete, its tensile, bending, cracking and wear resistance, impact resistance, fatigue resistance, toughness and other properties have significantly improved, it not only makes the surface thinning, shrinkage spacing increases, improve the road The use of performance, to extend the service life of the road, but also save on project costs and shorten the construction period.
