摘要
研究了使用硫酸亚锡降低水泥中 Cr^6＋的方法。结果表明，在1t 水泥中只要加入9．19-12．40g 的改性硫酸亚锡即可将 Cr^6＋的质量分数降低1mg／kg。将硫酸亚锡引入水泥中，对促进建筑行业的安全、可持续发展有重要的意义。
The method by using stannous sulfate to reduce the content of Cr^6 ＋ in cement was studied.Ex-periments show that by adding 9.19 -12.40g modified stannous sulfate in 1t cement,the content of Cr^6 ＋can be reduced to be 1mg /kg.So using stannous sulfate in cement has great significance for promoting the safety and sustainability of construction business.
