| 摘 要： | 采用酸性环境下的加速试验方法，研究了不同时段类砂岩材料-砂浆的物理性质，测试了试样的波速，监测了溶液中H+、Ca2+浓度变化，发现在不同腐蚀阶段砂浆表现出来的物理性质相差较大，其反应过程具有阶段性和Ca2+离子溶出具有滞后性的特点。同时，对不同尺寸试样受酸腐蚀的影响程度进行了对比分析，为酸雨地区岩石和混凝土性质的研究提供了可借鉴的思路。

| Abstract: | The physical characteristics of mortar specimens made of cement:sand:water=1:3:0.5 and subjected to hydrochloric acid attack were investigated by means of the accelerated corrosion test. The variations of the longitudinal wave velocity of mortar specimens and the alternations of the concentration of hydrion and calcium ion in hydrochloric acid solution were inspected. The results show that the characteristic of chemical reactive stage is found; and the delayed action of the dissolved out Ca2+ is observed; then the scale effect of different specimens is analysed. |
