| 摘 要： | 文章对现浇钢筋混凝土楼板开裂的情况进行了现场调查,初步分析了现浇钢筋混凝土楼板开裂的性状和原因。利用现场使用的不同配合比的C30混凝土试件,分别在标准收缩养护和非标准收缩养护条件下的收缩值进行对比试验研究,探讨早期浇水养护对现浇混凝土收缩变形的补偿作用。

| Abstract: | Through a fieldwork on the cracking of cast-in-place reinforced concrete floor slabs,the article analyzes the characteristics and causes of the cracking.By comparing the shrinkages of C30 concrete samples of different mix proportions under the condition of standard and non-standard contraction curing,the article explores the compensation effect of watering curing at an early stage to the contraction and deformation of cast-in-place reinforced concrete. |
