灰色关联分析法在水泥基灌浆料配比优选中的应用
|
摘要
采用灰色关联分析法,分别利用均值化和初值化对数据进行处理,研究了胶砂比、水胶比以及稳定剂用量等因素与水泥基灌浆料抗压强度、流动性能等的灰色关联度。计算结果表明:水胶比与灌浆料的1 d、3 d及28 d抗压强度的相关性均最高,其次是胶砂比及减水剂掺量;水胶比、胶砂比对灌浆料流动性的影响程度基本相同,且高于其它因素;胶砂比对灌浆料拉伸粘结强度影响最大,水胶比、减水剂掺量对灌浆料拉伸粘结强度的影响程度基本相同。
The grey correlation between the factors such as C/S ratio,W/C ratio et al and the performance of cementitious grout such as compressive strength,fluidity et al were studied through grey correlation analysis. The data were processed using ini-tialization and average,respectively. The results show that the correlation between W/C ratio and the 1 d,3 d and 28 d compressive strength of cementitious grout is the highest,followed by the ratio of mortar and the amount of water reducing agent. The influence of C/S ratio and W/C ratio on the fluidity of grouting material is basically the same,and higher than other factors. The effect of C/S ratio on the tensile bond strength of grouting material is the highest. The effect of W/C ratio and water reducing agent on the tensile bond strength of grouting material is basically the same.
