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.
