耐火粘土及高礬土的塑性耐火材料及搗實混合物的標準分類The scc has the following advantages : remarkably reducing the noisy pollution and the worker s labor intensity in construction, deducing the rough surface or segregation because of missing - vibration or excessive - vibration in conventional construction, resolving the quality - defect problems resulting from lacking - vibration in the section of complex shapes and densely - packed reinforcement area. at the same time, large of industrial solid waste such as fly ash and blast furnace slag is utilized in the proportioning of scc. it is helpful in comprehensive utilization of resource and environment protection, so the scc belongs to " green concrete ", it is a branch of hpc which will be developed in the future
這種混凝土可以顯著降低混凝土施工中的噪音污染;大幅度減輕工人的勞動強度;減少傳統混凝土施工中因漏振或過振造成的麻面或離析;解決了配筋密集、結構復雜部位因振搗不足而造成的質量缺陷問題;同時,由於自密實混凝土在配製中,大量利用粉煤灰、高爐礦渣等工業固體廢棄物,有利於資源的綜合利用和生態環境的保護;從而被譽為「綠色混凝土」 ,是未來混凝土向高性能發展的方向之一。To best achieve the working performance of the said concrete, with the help of theology theory in the research, we have analyzed the principle of free - vibration densifying and shaping of mixed concrete, that is, with the perquisite of fluidity, the concrete should have good property of filling - up - space, penetration through voids of fixed steel reinforcement, adherence and prevention from losing water and segregation, and the conflict between anti - segregation and deforming capability should be sorted out
為得到自密實高性能混凝土的最佳工作性能,在研究中藉助流變學理論,分析研究了混凝土拌合物免振搗成型和密實的機理,在大流動性的前提下,要求混凝土具有良好的填充性、鋼筋間隙通過性和粘聚性,防止泌水、離析,解決變形能力與抗離析性能力的矛盾。Some respects of self - compacting high - strength concrete ( schsc ) made of fujian province ' s local material have been studied in this thesis as follows : 1. studies on microstructure of the schsc. three different mixed schsc and one normal high - strength concrete ( nhsc ) were observed by the scanning electron microscope at different sites and different ages of 1 day, 3 days, 7 days, 28 days and 60 days. from the test, the effects due to no vibrating and admixture on the microstructure of schsc were studied
通過四組強度等級相當,分別為普通混凝土、兩組不摻膨脹劑的自密實混凝土(其粉煤灰的摻量不同)和摻有膨脹劑的自密實混凝土,在同一養護齡期的條件下( 1天、 3天、 7天、 28天和60天) ,分別選擇粗骨料過渡區、細骨料過渡區、水泥石和砂坑作為觀測點,採用sem進行細觀掃描對比實驗,以研究自密實混凝土因免振搗的特性及摻合料對其骨料界面和水泥石結構的影響。Self - densifying high performance concrete is well - performing concrete with the good performance of fluidity, anti - segregation and filling - up - space. with its own gravity and without any vibration, it can automatically fill up the space in and between fixed shutters and form self - densified concrete structure of ideal dynamic property and durability, therefore, it can accelerate construction progress of a building, shorten the construction period, secure concrete quality and improve the building ' s durability. in the mean time, it is conducive as well for environment protection and effects remarkable social and economic efficiency
自密實混凝土屬于高性能混凝土,它具有高流動性、高抗離析性、高填充性的性能,在自重作用下無需振搗,自行填充模板空間,形成自密實的混凝土結構,有良好的力學性能和耐久性能,可以加快工程建設進度、縮短工期、有效控制混凝土的質量、提高建築物及構築物的耐久性,並有利於環境保護,具有較高的社會和經濟效益。分享友人
