摘要
作为传统建筑材料,水泥在国内已经有一百多年的使用历史。随着高质量发展的要求,不仅在性能上需要持续提高,在绿色、安全环保层面也面临更加严格的要求。目前大部分水泥原料采用废物利用,虽然节约了成本,但是随之而来的毒性控制问题仍需要技术进步。而毒性的主要来源是水溶性铬,在水溶性铬家族中又以水溶性六价铬毒性最强,因此对水溶性六价铬源头研究和防治迫在眉睫。对国内业界水泥中水溶性六价铬的来源以及毒性防治措施研究作一评述,进而对水泥未来发展趋势进行展望。
As a traditional building material,cement has been used for more than 100 years in China. With the requirements of high-quality development,not only the performance needs to be continuously improved,but also the green,safety and environmental protection are facing more stringent requirements. At present,most cement raw materials come from waste utilization.Although the cost is saved,the following toxicity control problems still need technical progress. The main source of toxicity is water-soluble chromium. Among the water-soluble chromium family,water-soluble hexavalent chromium is the most toxic. Therefore,it is urgent to study and prevent the source of water-soluble hexavalent chromium. This paper mainly reviews the domestic industry’s research on the source of water-soluble hexavalent chromium in cement and the toxicity prevention and treatment measures,and then prospects the future development trend of cement.
