独联体(原苏联)每年排放出100多万吨的制碱废渣,拟加以利用。但经分析研究,废渣中的钠钙氯化物含量较高(超过10%),流质废渣需将水分疏干及固化,以及渣中的水溶性化合物亦得消除,因此,未经加工处理的废渣不能直接用作沥青混凝土的填充料,否则效果极不理想,不能满足规定要求。 The Commonwealth of Independent States (former Soviet Union) emits more than 1 million tons of soda waste residue every year and is intended to be used. However, after analysis and research, the content of soda-calcium chloride in the waste slag is relatively high (more than 10%), the liquid residue needs to dry and solidify the water, and the water-soluble compounds in the residue have to be eliminated. Therefore, the untreated waste residue Can not be used directly as a filler for asphalt concrete, otherwise the effect is extremely unsatisfactory and cannot meet regulatory requirements.
