水泥抗硫酸盐侵蚀性能探讨

Approach on performance of sulphate resistance in cement

文章作者选用三种抗硫酸盐性能较好的#525铁铝酸盐水泥、#525抗硫酸盐水泥和#525中热硅酸盐水泥，加入粉煤灰或硅粉混合材料后，分别进行抗硫酸盐侵蚀性能的试验研究，研究结果表明，铁铝酸盐水泥本身抗硫酸性能良好，加入混合材料后，其抗硫酸盐性能无明显改善；而其他两种硅酸盐类水泥，加入硅粉或粉煤灰混合材料后，其抗酸盐性能均有改善作用。

Three kinds of cements which are highly sulphate resistant are presented in this study．The 525 ferrous－aluminate cement,#525 sulphate—resistant cement，and#525 medium－heat portland cement. Fly ash or silicon powder was separately charged into the three type cements in order to test the properties of sulphate resistance．The results show that the property of the ferrous－aluminate cement which has good performance itself is not improved obviously，but that of the other two type cements is improved．
