| 摘 要： | 针对高性能混凝土添加掺合料后早期收缩变形较普通混凝土复杂,研究了矿渣、粉煤灰、硅粉、减缩剂、减水剂对高性能混凝土收缩的影响,建立了混凝土施工期应力计算收缩模型,并与常用收缩模型进行了对比分析。结果表明,该模型更适合高性能混凝土收缩变形计算。

| Abstract: | The research on contraction of high-performance concrete affected by slag,ash,silica fume,concrete shrinkage reducing admixture and water reducing damixture indicates that early contraction distortion of high-performance concrete is more complex that of ordinary concrete.A practical model for calculating stressis given.Compared to ordinary model of contraction,the proposed model in this paper is more suitable for the contraction distortion calculation of high-performance concrete. |
