摘要
为了解决我国煤化工与冶金行业中的大量固体废弃物堆存问题,以煤气化渣、脱硫灰渣、矿渣、水泥为原料制备了固化剂,代替纯水泥后与黏土混合制备了流态固化土。采用粒度分析、力学性能测试、X射线衍射(XRD)及扫描电镜(SEM)等测试手段,研究了煤气化渣的粉磨特性、流态固化土的性能和固化剂的水化机理。
To address the significant issue of solid waste stockpiles between coal chemical and metallurgical industries in China,a curing agent was prepared by using coal gasification slag(CGS),flue gas desulfurization residue,slag,and cement as raw materials.This curing agent,instead of pure cement mixed with clay,was used to produce fluid solidifying soil.The grinding characteristics of CGS,the properties of fluid solidifying soil and the hydration mechanism of the curing agent were investigated by using particle size analysis,mechanical property tests,X-ray diffraction(XRD),and scanning electron microscopy(SEM).
