brushed surface meaning in English
刷毛的混凝土路面
刷面层
Examples
- Following is the factors ideating with the surface of old concrete in different way ( including brushing surface , chiseling surface , cleaving surface ) , adherence agent ( including cement slurry , cement sand slurry , cement slurry with the u expansion agent ) , the freeze - thaw circulation times and air - entraining . as a result , we found that the roughness influence on the adhesion capability of the new on old concrete to a large degree . the larger rougeness is , the larger the splitting tensile strength on the adhension face is . the kind of adhesion agent is also influence on the adherence capability of new on old concrete . the circulation times of freez - thaw have a large influence on the splitting tensile strength of adherence face of new on old concrete . the analysis of tests give some advices to the practical engineering
主要考察了老混凝土表面不同处理方式(刷毛面，凿毛面，劈裂面) 、界面粘结剂类型(水泥净浆，水泥砂浆， u型膨胀剂水泥浆) 、冻融循环次数等对新老混凝土粘结面劈拉强度的影响，以及冻融作用下新混凝土加气对粘结面劈拉强度的影响。试验结果表明，粗糙度对新老混凝土粘结性能有重要影响，随着粘结面粗糙度的增大，粘结面劈拉强度不断增加；界面粘结剂类型对新老混凝土粘结性能有一定影响，在冻融作用下， u型膨胀剂水泥浆粘结效果不如水泥净浆和水泥砂浆；冻融循环对粘结面劈拉强度有较大影响，加气能明显改善新老混凝土粘结面的抗冻能力。
