摘要
根据内蒙古河套灌区土质特性,通过正交试验方法分析得到复掺玻璃纤维粉煤灰水泥土最优配合比,进而通过选取不同浓度的Na2SO4溶液侵蚀该水泥土试件,测得相应的无侧限抗压强度值,分析在硫酸盐溶液的侵蚀环境下,不同SO2-4浓度对水泥土耐久性能的影响规律。结果表明:当SO2-4浓度很小时,对该水泥土的强度有促进作用。随着SO2-4浓度的提高,水泥土无侧限抗压强度显著降低。
Based on the characteristics of the soil in Hetao,Inner Mongolia and analysis of the orthogonal experiment method,We obtained the optimal proportion of Complex-dopedglassfiber reinforced fly ashcement.Through selecting different concentrations of Na2 SO4 solution to erode the Specimen,we detected the corresponding unconfined compressive strength and analyzed the effects of different concentrations of SO2-4 on the durability of cement under the condition of the erosion of sulphate solution.The results show that when the concentration of SO2-4 is very low,it improves the strength of the cement.With the increasing con-centration of SO2-4 ,unconfined compressive strength is decreased significantly.
