摘要： 为研究海水侵蚀作用下充填材料的服役性能,对试样进行单轴抗压强度和低场核磁测试,研究了质量分数为5%的SO2-4和质量分数为3.5%的Cl-侵蚀下充填材料的变化规律,揭示不同侵蚀离子对石灰石尾矿基充填材料力学性能的影响。试验结果表明:Cl-和SO2-4对石灰石尾矿基充填材料抗压强度具有提升作用,随着Cl-和SO2-4质量分数的增加,充填材料孔径及孔隙率均呈现减小的趋势,结石体中少害孔的个数随着养护龄期的增加而逐渐增多,多害孔的个数减少。在侵蚀条件下SO2-4和Cl-对充填材料中硅铝质组分的水化反应具有促进作用,C-S-A-H凝胶和N-C-S-A-H凝胶增多,生成的水化产物充填了孔隙,使结构更加密实;同时SO2-4可与水化产物C-S-A-H凝胶发生反应,生成钙矾石,充实孔隙,使孔隙率减小。研究成果对滨海岩溶充填工程服役性能评价具有一定指导作用。
