| 中文摘要: |
| 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. |
| 英文摘要: |
| The article presents an introduction to the application of steel-fiber concrete material to the repair of old concrete road surface and certifies, on the basis of the analyses toward the experimental hardness of different prescriptions, the feasibility of such applications through the example of a certain project. Steel-fiber concrete is a compound material of excellent performance. Compared with ordinary concrete, it has been greatly improved in such aspects as anti-pulling, anti-bending, anti-erosion, anti-impact, anti-exhaustion, toughness and tenacity etc. It thins the road surface but lengthens its life, broadens the seams and elevates its performance, and saves the construction capital and shortens the time. |
