不同硫酸盐溶液和侵蚀周期对玻化微珠保温砂浆抗压强度的影响研究

Impact of sulfate solution and erosion cycle on compressive strength of glazed hollow bead mortar

将玻化微珠保温砂浆试件分别置于Na2SO4溶液环境、CaSO4溶液环境和MgSO4溶液环境中,测得其在不同侵蚀周期下的抗压强度,分析了各溶液在不同浓度下抗压强度的变化规律。用双因素方差分析法比较了同一周期下不同溶液及其浓度对抗压强度的显著性影响。建立了各溶液中试件的抗压强度折减率和溶液浓度及侵蚀天数的本构关系。

Regulation of compressive strength change is analyzed after specimens placed in Na2SO4 solution,CaSO4 solution and MgSO4 solution after different period.Significant impact of sulfate solution and erosion cycle on compressive strength was compared by two-factor analysis of variance.The relationship between discount rate of compressive strength,concentration of the solution and erosion cycle were established.
