冻融循环对非水反应高聚物注浆材料抗压性能的影响研究

Study on the Effects of Freeze-thaw Cycles on Compressive Property of Polymer Grouting Material

文章通过室内对不同密度非水反应高聚物注浆材料进行冻融循环试验,得到在不同冻融循环条件下材料的抗压强度及抗压损伤度,分析了密度和冻融循环作用次数对高聚物注浆材料抗压性能的影响。结果表明:抗压强度与冻融循环次数、试件密度呈二次多项式回归关系;密度为0.4g/cm^(3)的非水反应高聚物注浆材料受到冻融循环作用的影响最小。

Through the freeze-thaw cycle test,the compressive strength and compressive damage degree of the non-water reacted polymer grouting material with different densities under different freeze-thaw cycles were obtained and the effects of density and freeze-thaw cycles on the compressive performance of polymer grouting materials were analyzed.The test results show that the compressive strength has quadratic polynomial regression relationship with freeze-thaw cycles and specimen density;the non-aqueous reactive polymer grouting material with a density of 0.4 g/cm^(3) is minimally affected by the freeze-thaw cycle.
