矿物掺合料对水泥砂浆抗硫酸铵腐蚀的影响及灰色关联分析
Effect of mineral admixture on cement mortar 's anti-ammonium sulfate corrosion and their grey relational analysis
摘要
Abstract
This paper studies the effect of mineral admixture on cement mortar's anti-ammonium sulfate corrosion by observing the surface morphology, compressive strength test, mass loss variations and gray correlation analysis of the mortar test block soaked in the (NH4)2SO4 solution with the concentration of 5 %. The gray correlation analysis method was applied to analyze the effect of mineral dosage on the compressive strength. The research results show that the micro aggregate effect and morphological effect of the fly ash are favorable than that of slag, and the two have complementary effect in their working capacities. The mixing of mineral admixtures can improve the corrosion resistance of cement mortar with ammonium sulfate with obvious inhibitory and preventive effect. The hierarchical order of the several mineral admixtures and their percentages on cement mortar's anti-ammonium sulfate corrosion is:fly ash (20%), 20%fly ash+40%powder, 40%ore, 60%powder, the blank sample. It is feasible to analyze mineral admixture on cement mortar ammonium sulfate corrosion through the grey relational system theory.关键词
