An analysis of the deterioration mechanism of a grouting stone under the ion erosion
-
Abstract
Research on the degradation mechanism of cement-water glass grouting stones (C-S stones) in an environment of ion erosion is lacking. The unconfined compressive strength test is conducted to analyze the change law of macro-mechanical properties of the C-S calculus body under different age conditions after the erosion of three different concentrations of sulfate. A combination of SEM, EDS and XRD is used to observe the mesostructure and chemical composition changes of the stone body, and reveal the mechanism of ion erosion damage of the grouting stone body. The results show that within 28 days of erosion, different concentrations of ionic solutions has no significant effect on the growth of stone strength. From 28 to 90 days of erosion, the growth of stone strength in high concentration solution is significantly degraded, and when the concentration of
