摘要:

研究了硅粉对提高污水工程用混凝土中砂浆耐污水腐蚀性能的影响.以污水中常见的硫酸盐、卤盐、弱酸和微生物等作为腐蚀介质,测试了砂浆浸泡于各种腐蚀液中的质量、强度损失.结果表明,硅粉对提高污水管用混凝土中砂浆耐污水腐蚀性能具有一定效果.

Abstract:

This study focuses on the influence of the silica fume on sewage corrosion resistance of mortar from concrete of sewage project.On the basis of several corrosion source which is common in sewage,four corrosion solutions are designed in this experiment,including sulfate corrosion,salt corrosion,acid corrosion and microbe corrosion.Through testing the loss of mass and strength of the mortar which is put in the corrosion solution,it is found that silica fume can improve the sewage corrosion resistance of mortar to some extent.
