| 摘 要： | 采用滑模摊铺机进行路缘石混凝土摊铺施工时，由于设计路缘石混凝土标号较高，厚度较薄，在施工中往往出现混凝土抗裂性差以及施工和易性不好等缺点，通过试验，在混凝土中掺加适量的粉煤灰，可对路缘石的施工质量有很大的改善和提高。

| Abstract: | When the slip-form paver is used in curbstone concrete spreading construction, because the grade of designed curbstone concrete is comparatively superior and its thickness is comparatively thin, the crack resistance and the construction workability of concrete are usually bad in construction. By tests, it is found that mixing a little fly ash into concrete can greatly improve the con- struction quality of curbstone. |
