| 摘 要： | 在不同的试验条件下对抗硫酸盐侵蚀进行试验，研究了成型压力和浸泡时间对混凝土抗硫酸盐侵蚀性能的影响．结果表明：按现有规范规定的成型压力取得的试验结果偏大，对评价侵蚀性能不利，采用振动成型更接近实际情况；随着浸泡时间的延长，混凝土的耐腐蚀性均有所下降，建议延长浸泡时间评价混凝土的抗腐性能．

| Abstract: | The influence of molding pressure and dunking time on the sulfate attack resistance was studied with experiment. The experiment shows the result figure obtained from the existing specification is much bigger, which is inaccurate to evaluate the concrete sulfate attack, and the result is much closer to the actual situation when vibration molding is adopted. The corrosivity resistant nature of concrete will decline with the prolonging of dunking time, so prolonging the dunking time to evaluate the corrosivity resistant nature of concrete is suggested. |
