| 摘 要： | 将不同配合比混凝土在不同侵蚀条件下进行抗硫酸盐侵蚀试验,试验结果表明:粉煤灰取代部分水泥可以改善混凝土抗硫酸盐侵蚀能力;粉煤灰取代水泥量越大,混凝土抗硫酸盐侵蚀能力越强,尤其对于高浓度硫酸盐溶液更是这样;粉煤灰混凝土抗侵蚀能力,随侵蚀介质浓度增加,下降的程度较基准混凝土小。

| Abstract: | The tests of concrete sulphate-corrosion resistance are carried out and some results obtained.Firstly,fly ash substituting for some cement in concrete can improve concrete sulphate-corrosion resistance.Secondly,the higher substitution ratio of fly ash for cement is,the stronger concrete resists to sulphate-corrosion,particularly under higher concentration sulphate solution.Thirdly,when the concentration of sulphate solution increases,the concrete sulphate-corrosion resistance decreases,but there is a smaller decrease in fly ash concrete than in ordinary concrete. |
