超细钢渣及高性能混凝土掺合料的最新进展

Ultrafine Steel Slag and Latest Advance in Blending Materials of High Performance Concrete

钢渣是中国钢铁产业大量排放的固体废渣。随着国家“十一五”规划以及国家未来发展的中长期纲要的实施,钢渣的循环利用必将成为能源环境保护的重要措施,意义重大。通过对钢渣成分的分析、钢渣的研究和目前钢渣利用现状的论述,说明了磁选、球磨以及激发剂加速钢渣水化等技术在高性能混凝土超细钢渣掺合料研究中的重要作用。钢渣的循环利用将成为循环经济的重大增长点,也必将给整个社会带来巨大的经济效益。

Steel slag is a solid waste discharged in large quantities by the iron and steel industry in China. With the implementation of the state Eleventh Five-Year Plan and the state＇s medium and long term program for the future development, the recycling of steel slag will inevitably become an important measure for the energy environment protection and therefore will be of great significance. Through the description of the analysis of the composition of steel slag, the research on steel slag and the state quo of its utilization, the paper illustrates the important role of the techniques such as magnetic separation, ball mill grinding and the acceleration of the steel slag hydration by excitant in the research on using uhrafine steel slag as a blending material in producing high performance concrete. The recycling of steel slag will become a major growth point in the recycle economy and will be sure to bring an enormous economic benefit to the whole society.
