Self - compacting concrete is a kind of concrete with low w / b ratio and good workability, which does not need to pug. it is a trend for both the researchers and the concrete engineer
自密實混凝土是一種在較低水灰比條件下,不泌水,不離析,不需振搗或只需少量振搗即達到均勻密實的混凝土,是混凝土工程技術的一個重要發展方向,也是目前國內外學者研究的一個熱點。In this paper, the so preparing self - compacting concrete with low and middle strength using super fine mountain sand artifical sand and phosphorus slag is studied systemically. through the study the influence of the shape, the proportion of the dust and the grade of sand to the workability and the mechanical property of self - compacting concrete, it is found that super fine mountain sand artifical sand are not suit to prepare low and middle strength self - compacting concrete, but when they are combined and the additive and assistant band material are used, c20 - c40 high performance self - compacting concrete is prepared ; the corresponding additive is developed to solve the delamination caused by the low proportion of banding material ; the evaluating system for the workability of low and middle strength self - compacting concrete is built ; the controlling method for production, construction and curing was set up. and the result of the research is applied into several projects
通過分析特細山砂和機制砂的顆粒形態、粉末含量、顆粒級配等特性對自密實混凝土的工作性能和力學性能的影響,發現特細山砂、機制砂不宜單獨用於配製中低強度等級自密實混凝土,宜將特細山砂和機制砂進行合理復配,並選擇合適的外加劑和礦物摻合料,優化配合比設計,可生產c20 c40中低強度等級自密實高性能混凝土;研製開發出了具有高效減水、保塑、抗離析功能的外加劑,有效解決了中低強度等級自密實混凝土由於膠凝材料用量少而出現的離析、泌水問題;應用正交設計方法,對因素和水平進行合理選擇,確定了生產中低等級自密實混凝土的最優配合比;建立了中低強度等級自密實混凝土的工作性評價體系;提出了生產、施工及養護的質量控制技術方法。This is generally accomplished by using water - reducing admixtures. specify air - entrained concrete for outdoor slabs subjected to freezing weather
也可以使用更高坍落度(的混凝土) ,但(製作混凝土的)混合物必須是設計用於製作不過量泌水和/或分離(混凝土)的(混合物)
