砂型粗糙度 的英文怎麼說
中文拼音 [shāxíngcūcāodù]
砂型粗糙度
英文
sand roughness-
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處理方式（刷毛面，鑿毛面，劈裂面） 、界面粘結劑類型（水泥凈漿，水泥砂漿， u型膨脹劑水泥漿） 、凍融循環次數等對新老混凝土粘結面劈拉強度的影響，以及凍融作用下新混凝土加氣對粘結面劈拉強度的影響。試驗結果表明，粗糙度對新老混凝土粘結性能有重要影響，隨著粘結面粗糙度的增大，粘結面劈拉強度不斷增加；界面粘結劑類型對新老混凝土粘結性能有一定影響，在凍融作用下， u型膨脹劑水泥漿粘結效果不如水泥凈漿和水泥砂漿；凍融循環對粘結面劈拉強度有較大影響，加氣能明顯改善新老混凝土粘結面的抗凍能力。2, the bearings production and processing equipment signal processing equipment, bearing cleaning equipment, packaging equipment bearings, the bearings production equipment, round instrument, blank processing equipment, double - end grinders, electric spindle and wheel grinding oilstone and other materials, printers marking machine measuring instrument, spherical roller processing equipment, raceway - seiki, roughness measuring instrument, the finish detector converter, hardness needle - sorting machine and new materials, lubricants, preservatives, cleaning agents, testing instruments
