| 摘 要： | 通过三水平三因素的正交试验,研究了不同掺合料制备的9组不同强度等级混凝土在3%~9%NaCl溶液浓度下RCM的试验结果。研究结果表明:在浓度为3%、5%、7%、9%时,混凝土的氯离子扩散系数DRCM随着NaCl溶液浓度的提高而增加,且9组试验结果的正交分析结果基本一致的。

| Abstract: | Based on three levels of three factors in orthogonal test,nine groups of concretes with different strength levels have been prepared with different admixtures, DRCM was determined in the 3% - 9% NaC1 solution concentration. The results showed that： in the concentration of 3 %, 5 %,7 % and 9%, the chloride dif- fusion coefficient DRcM increased with NaC1 concentration and 9 groups of orthogonal analysis of test results were basically same. |
