Application of fly ash/granulated blast-furnace slag cementing material for immobilization of Pb2+

摘要：

　　Based on activation and synergistic effect among various materials,a low-cost cementing material,FGC binder,was prepared by using fly ash,granulated blast-furnace slag(BFS),carbide slag and compound activator.The results showed that the immobilization efficiency of FGC binder for Pb2+is higher than that of OPC cement.The hydration productsand mechanism of immobilization were analyzed by using XRD.The major products of FGC binder are C-S-H,C-A-H,ettringite and zeolite-like materials.Under the experimental conditions,the Pb2+curing efficiency of FGC binder is 1.04~1.24 times that of ordinary Portland cement.
