水泥中混合材对水溶性铬(Ⅵ)的影响

Effect of admixture on water-soluble chromium(Ⅵ)in cement

水溶性铬(Ⅵ)是水泥中有害元素之一,由于其有较好的水溶性,对人体及环境造成危害。本文选择华北地区常用的水泥混合材,测试其对水泥中水溶性铬(Ⅵ)的影响,以便于减少水泥中水溶性铬(Ⅵ)的含量,降低其对人体和环境的危害。

Water-soluble chromium(Ⅵ)is one of the harmful elements in cement.Because of its good water-solubility,it will cause harm to human body and environment.In this paper,the cement admixture commonly used in North China was selected to test its influence on water-soluble chromium(Ⅵ)in cement,so as to reduce the content of water-soluble chromium(Ⅵ)in cement and reduce its harm to human body and environment.
