結果表明：金剛石鋸片鋸切混凝土的過程表現為高速據切過程中金剛石據片的沖擊引起混凝土表層斷裂破碎，水泥石子等在切削區內層受到金剛石磨粒的微切削作用形成粉屑，以及鋼纖維和鋼絲發生金屬塑性變形斷裂或被拔拉而斷裂的過程。Based on the principles of designs of self - compacting and light aggregate concrete mix, sclc of lc30 - lc50 was developed by using absolute volume method. the main factors affecting the workability of sclc were studied by adopting the modified l - 800 fluidity instrument. the results indicate that the key techniques insuring good workability of sclc are about 30 % first - grade fly ash, about 50 % volume sand ratio, 2 % ~ 6 % dosages of silicon fume and compounded superplasticicizers with viscous ingredient
採用改進l - 800流動儀，研究了影響lc40自密實輕骨料高性能混凝土工作性的主要因素，結果表明：粉煤灰摻量保持30左右，硅灰摻量為2 6 ，體積砂率為50左右和摻加具有粘塑組分的復合高效減水劑是保證sclc拌合物具有較好工作性的關鍵。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。2 ) to a certainty of sand percentage, concretes with moderate critical sand percentage which changed in about 36 % - 43 % were more sensitive to plastic shrinkage cracking than concretes with lower or higher sand percentage. 3 ) concrete made with lower strength grading cement was more prone to plastic shrinkage cracking than that of concrete made with higher strength grading cement
4 ）粉煤灰和硅灰對混凝土塑性收縮裂縫的影響與拌合物的實際水膠比有關，存在一個水膠比界限，在此界限之上，摻入粉煤灰或硅灰的混凝土較易開裂，在此界限之下，粉煤灰或硅灰高性能混凝土對塑性收縮裂縫具有抑制作用。The results indicate that less dosage of water, clay, bentonite and larger dosage of cement, and mixing coal ash and admixture can increase compressive strength of plastic concrete
結果表明，減小水膠比及黏土和膨潤土的用量，增加水泥用量，摻加粉煤灰和外加劑，均可提高塑性混凝土的抗壓強度。分享友人
