中文摘要：
采用不同浓度的硫酸溶液作为侵蚀环境，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，研究了在不同侵蚀龄期条件下，混凝土试块强度及抗蚀系数的变化规律。试验显示，试块强度的增长随着侵蚀溶液浓度的增大及侵蚀龄期的增长而有所放缓，试块的抗蚀系数随着侵蚀溶液浓度及龄期的增大而明显减小，同时掺有粉煤灰的混凝土试块抗蚀性能有一定程度的提高。
英文摘要：
In the erosion environments with different concentrations of sulfuric acid solution, the block strengths and resist coefficients for two groups of concrets mixed with fly ash and non-fly ash were studied under various erosion age conditions,respectively.The test resuits show that the resisting erosion concrete block with fly ash performs better than that with non-fly ash.The block strength increasing rate become slowed down and the block resist coefficient reduces obviously as the increasing of sulfuric acid 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.
