摘要
为了获得废旧闸瓦摩擦回收料对混凝土耐久性的影响机理,本文初步研究了掺量分别为0%、5%、10%废旧闸瓦摩擦回收料对混凝土抗硫酸盐侵蚀的影响。采用扫描电子显微镜分析了侵蚀前后试件的微观形貌。结果表明:废旧闸瓦摩擦回收料的掺入不会使混凝土的强度降低,还能进一步改善混凝土的抗硫酸盐性能。
The effects of friction reclaimed materials of waste brake-shoe （FRMWBS）, with content of 0%, 5% and 10% respectively, on concrete durability were studied. The scanning electron microscopy was employed to analyze the micro- topography of concrete before and after erosion by sulphate. The results showed that the mixing of FRMWBS would further improve the sulfate attack resistance ability of concrete rather than decreasing its compressive strength.
