| 摘 要： | 研究了硫铝酸盐水泥体系下重金属铅对水泥水化进程的影响,以及硫铝酸盐水泥对重金属铅的固化/稳定效果分析.研究表明,重金属铅掺量达到一定阀值(本试验条件下为2.0%)时,才会对硫铝酸盐水泥水化产生明显影响.用硫铝酸盐水泥对重金属铅进行固化效果良好,重金属铅通过物理固封、替代或吸附等形式可固化入水化产物结构中,且2.0%硝酸铅掺量浸出毒性试验结果控制在国家标准要求之内.

| Abstract: | The influence of heavy metal Pb on the sulphoaluminate cement hydration process and the solidification /stabilization effect of sulphoaluminate cement on heavy metal Pb were studied in this paper. The results shown that:It would take on obviously effect to the sulphoaluminate cement hydration process only that the mixed quantity of heavy metal reached certain threshold(2.0% under this experiment) . Sulphoaluminate cement immobilization effect of heavy metal Pb was good and heavy metals Pb was immobilized wi... |
