| 摘 要： | 以掺有粉煤灰和不掺粉煤灰的两组混凝土试块作为研究对象,通过室内模拟试验研究了不同浓度硫酸镁溶液侵蚀环境下,混凝土试块抗压强度及峰值应变随龄期的变化规律。由试验可知,混凝土强度的增长随着时间的增长呈现先增大后缓慢增长的趋势。相同龄期下,随着硫酸镁溶液浓度的增加,试块峰值应变先增大后减小,并且得到粉煤灰的掺入对试块力学性能有一定程度提高。

| 关 键 词： | 粉煤灰 混凝土 峰值应变 强度 MgSO |

| Abstract: | In the erosion environments with different concentrations of MgSO4 solution, the block strengths and peak strain for two groups of concrets mixed with fly ash and non-fly ash are studied under various erosion age conditions, respectively. The test results show that the resisting erosion concrete block with fly ash performs better than that with non-fly ash. The block strength increasing rate become slow down and the block peak strain grow increase then decrease as the increasing of MgSO4 solution concentration and erosion age, at the same time, the resisting erosion concrete block with fly ash performs better than that with non-fly ash. |

| Keywords: | fly ash concrete peak strain strength MgSO4 |
