  1. 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低強度等自密實混凝土,宜將特細山砂和機制砂進行合理復配,並擇合適的外加劑和摻合料,優化配合比設計,可生c20 c40低強度等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,有效解決了低強度等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擇,確定了生低等自密實混凝土的最優配合比;建立了低強度等自密實混凝土的工作性評價體系;提出了生、施工及養護的質量控制技術方法。
