摘　　要：文章研究了不同水泥种类和水胶比的净浆试件和灌浆结石体在不同pH值侵蚀溶液作用下抗溶蚀特性。结果表明:在中性水中溶蚀的试件,溶蚀进程非常缓慢;水泥灌浆材料抗溶蚀性能随侵蚀溶液pH增大而增强;相比于普通硅酸盐水泥,CGM超细水泥有更好的抗溶蚀性,与花岗岩形成的结石体的使用寿命更长;水胶比为0。5的超细水泥净浆试件的抗溶蚀性能最好;灌浆结石体试件溶蚀规律与净浆试件溶蚀规律相近。The article investigated the anti-erosion characteristics of net mortar specimens and grouted stone bodies with different cement types and water-cement ratios under the action of erosion solutions of different pH values.The results show that:the dissolution process of specimens dissolved in neutral water is very slow;the dissolution resistance of cement grouting materials increases with the increase of erosion solution pH;compared with ordinary silicate cement,CGM ultra-fine cement has a better dissolution resistance,and the service life of the stone body formed with granite is longer;the dissolution resistance of the net mortar specimen of ultra-fine cement with the water-to-cement ratio of 0.5 is the best;the dissolution law of grouted stone body specimen is similar to the dissolution law of the net mortar specimen.The dissolution and erosion law of the grouted stone specimen is similar to that of the net mortar specimen.
