| 摘 要： | 在酸性环境条件下进行的加速腐蚀试验，研究了不同时段和不同酸度条件下类砂岩材料砂浆的纵波性质变化规律，分析了化学反应速率、酸液中H+，Ca2+浓度变化和形成胶体化合物性质之间的联系，发现反应过程具有阶段性和离子溶出具有滞后性的特征，为酸雨地区混凝土和砂岩力学性质的研究提供了可以借鉴的思路。

| Abstract: | The variations of the longitudinal wave velocity of mortar specimens made of cement:sand:water=1:3:0.5 and subjected to different hydrochloric acid attacks were investigated by means of the accelerated corroded test. The relationship including the chemical reactive rate, the alternation of the concentration of hydrion and calcium ion and the properties of formed gel compounds were inspected. The characteristics of chemical reactive stage and the delayed action of the dissolved out Ca2 were observed. |

| Keywords: | hydrochloric acid attack accelerated corroded test longitudinal wave velocity chemical reaction |
