粉磨时间对矿物掺合料颗粒特性的影响

The effects of grinding time on property of particle mineral mixture

研究了粉磨时间对粉煤灰、矿渣和钢渣等工业废渣的颗粒特征和性能的影响。通过测试各物料在不同粉磨时间下的粒径分布、强度活性指数和微观形貌表明粉磨对各物料颗粒特征和性能的影响是不同的。这说明针对不同物料应该建立独立的、经济的粉磨制度。同时,对各物料颗粒性能进行的研究将为高性能辅助性胶凝材料级配研究提供依据。

Study on the effects of grinding time on the particle characteristics and properties of industrial wastes such as fly ash, slag and steel slag. Experiments contained the researches on the particle distribution, the strength activity index and the morphology of different materials under different grinding time. Results showed the effects of grinding time on materials particle property were different, it indicated the individual and economical grinding techniques of different industrial wastes should be established. Furthermore, the studies on the particle properties of different industrial wastes in this paper will help to study the particle gradation of high performance supplementary cementing material.
