| 摘 要： | 通过观察,试块表观现象在一定程度上反映了硫酸钠溶液对混凝土侵蚀的严重程度,质量变化反映了硫酸钠侵蚀产物随时间的生成及变化规律,通过力学试验研究了硫酸钠溶液浓度、水灰比、长期浸泡对混凝土抗压和劈裂抗拉强度的影响规律。结果表明：试块质量呈现先下降、后上升、再下降的总趋势,低水灰比混凝土的强度对硫酸钠溶液侵蚀较为敏感,侵蚀溶...

| Abstract: | Phenomenon observed from the apparent,to some extent,reflects the severity of the concrete at-tacked by sulfate.The quality changes reflect the law of erosion's formation and variation over time.By mechan-ical experiment,the study was made about the concentration of sodium sulfate solution,water-cement ratio,long-term immersion impact on the compressive strength and the splitting tensile strength.It is proved that the quality of specimen decreased and then increased at first and then the general trend of de... |
