圬工砌塊的試驗方法.混凝土人造石和天然石圬工砌塊因毛細作用的吸水率及粘土圬工砌塊吸水初速的測定Methods of test for masonry units - part 11 : determination of water absorption of aggregate concrete, manufactured stone and natural stone masonry units due to capillary action and the initial rate of water absorption of clay masonry units
圬工單位的試驗方法.第11部分:集料混凝土人造石和天然石圬工單位因毛細作用的吸水率及粘土圬工單位吸水初速的測定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。In this paper, 45 e. coli strains isolated from chicken farms in sichuan province were determined to be the pathogenic e. coli by animal test. type 1 pili of 45 strains isolated was detected by msha. the pila gene of 45 avian pathogenic e. coli strains were amplified by the polymerase chain reaction ( pcr ) with primers designed according to the sequence of the pila gene in genbank. results showed that pcr was more sensitive, faster and more characteristic than msha to detect type 1 pili
