摘要
通过对包钢钢渣进行一系列的试验,全面分析了钢渣的化学成分、物理力学性能、矿相组成、稳定性以及放射性.研究结果表明,当钢渣的存放期为一年以上时,其压碎值、游离氧化钙含量、稳定性以及放射性均满足国家及行业有关标准要求,可以作为公路路基填料.研究结果得到了工程实践的验证.
By performing a series of tests to steel-making slag produced by Baotou Iron and Steel Company, the chemical composition, physical-mechanical property, mineral constituent, stability and radionactivity of the slag are analyzed. It is shown that when the slag is put in storage for more than one year, the crush value, free-CaO content, stability and radionactivity of the slag are all in conformity to the national standards and related trade criterions and can be used as the subgrade material of highway. This result has also been verified by practical projects.
