| 标题 |
| 大风干旱地区预防混凝土结构开裂的试验研究(52卷) |
| 英文标题 |
| Experimental study on crack-prevention in concrete structure in strong-wind and severe-drought region |
| 摘要 |
| 针对西北大风、干旱的气候特征，选取具有代表性区段浇筑墩、道床板混凝土，从混凝土的内养护和外养护两方面出发，研究了内养护材料、模板类型和新型外养护方式对混凝土结构抗裂性的影响。结果表明，内养护材料能显著减小混凝土的早期收缩，降低混凝土早期开裂程度，同时不降低混凝土的强度和耐久性；透水模板布和保湿养护布不仅可以显著改善混凝土结构的外观，还能有效预防混凝土开裂和降低混凝土结构表面的渗透性。 |
