摘要
本文运用扫描电镜、压汞测孔、pH计和浸烘循环失重法,研究了煤矸石的品质、CaO掺量和w/c对煤矸石混凝土中钢筋的失重率、电位与混凝土保护层的pH值、结构的影响。研究结果表明:配比合适的煤矸石混凝土的护筋性能良好。
In this paper,the effects of quality of gangue amount ofCaO added and w/c ratio upon the weight loss rate and potential of steelas well as pH value and structure of concrete cover of gangue concreteare analysed by means of mercury intrusion porosimetry,scanning electronmicroscopy,pH value measurement and soak-dry cycling.The results ofthis study confirm that the gangue concrete with appropriate proportiongives a good protection for steel.
