以贵州省镍铁矿渣为主要骨料原料,粒径<0.15mm的镍铁矿渣磨成粉后利用其硅质、铝质等成分,激发其潜在活性替代部分胶凝材料,制备一种复合保温砌块,对镍铁矿渣的化学成分、矿物质、放射性、重金属离子浸出毒性及其复合保温砌块的性能等进行了研究;提供了镍铁矿渣综合利用途径,促进了镍铁矿渣就地即产即用的推广。
In Guizhou province, ferronickel slag is taken as the main raw material, ferronickel slag with particle size <0.15mm is ground into powder and then its silicon, aluminum and other components are used to stimulate its potential activity to replace part of the cementitious material to prepare a Composite insulation block, the chemical composition of nickel-iron slag, minerals, radioactive, heavy metal ions leaching toxicity and the performance of composite thermal block, etc., to provide a comprehensive utilization of nickel-iron slag approach to promote the nickel-iron Slag that is ready to use in-place promotion.
