特厚表土层冻结井壁C80高性能混凝土配比研究
Concrete mixture ratio research of C80 HPC in extraordinary depth surface soil
【摘要】 针对特厚表土层冻结井壁的特点,运用正交试验进行C80高性能混凝土配比试验,通过对试验结果的极差分析、回归分析和验证性试验,得到特厚表土层冻结井壁C80高性能混凝土最佳配合比。
【Abstract】 This paper put forward compound principle of HSAHPC according to the character of freezing shaft linging in extraordinary depth surface soil.Do experiment by means of orthogonal test.Then obtaining optimum mixture ratio through orthogonal test,range analysis and regression analysis.
