Unbound and hydraulically bound mixtures - part 44 : test methods for the determination of the alpha coefficient of vitrified blast furnace slag 松散的和液力粘合的混合料.第44部分:玻化高炉矿渣的系数测定用试验方法
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 这种混凝土可以显著降低混凝土施工中的噪音污染；大幅度减轻工人的劳动强度；减少传统混凝土施工中因漏振或过振造成的麻面或离析；解决了配筋密集、结构复杂部位因振捣不足而造成的质量缺陷问题；同时，由于自密实混凝土在配制中，大量利用粉煤灰、高炉矿渣等工业固体废弃物，有利于资源的综合利用和生态环境的保护；从而被誉为“绿色混凝土” ，是未来混凝土向高性能发展的方向之一。
It focuses on the theory of the mineral functional materials " improving the anti - chloride permeability and the chloride binding . the main achievements of this article include : 1 ) use the technology of xrd , sem , bet , laser particle size distributor etc to test the component , the construction , particle size distributor , specific surface etc of micro - silica , ultra - fined slag , high quality fly ash , meta - kaolin clay , four types of the mineral functional material , theoretically analysis the functions which the four mineral functional minerals act on cement concrete , namely pozzolanicity effect , filling effect , micro - aggregate effect , surface adsorption effect and so bring into play the affect of plastification , lowing of temperature , reinforcement , improvement of durability . base on this analysis we can conclude that the proper diameter of the mineral functional material is 5 m - 15 m , that is blain fineness 4500cm2 / g - 7500cm2 / g 本论文的主要成果包括以下几个方面： ( 1 )采用xrd 、 sem 、 bet 、激光粒度分析仪等多种测试手段，探明了以硅灰，超细磨粒化高炉矿渣，优质粉煤灰及偏高岭土超细粉等4种超细矿物功能材料的组成、结构、粒度分布、比表面积等基本性质；从理论上分析了矿物功能材料在混凝土中的4种效应，即火山灰效应、填充密实效应、微集料效应、表面吸附效应，并由此发挥出增塑、温峰削减(降热) ，增强及耐久性改善等作用；通过相关理论分析，推导出矿物功能材料的合理粒径范围在5 m 15 m ，即勃氏比表面积为4500cm ~ 2 g 7500cm ~ 2 g 。
Abstract : during construction of the capital international airport ' s garage building project , the c50 and over c60 high performance concrete has been adopted for its construction . for the aim of 1 , to get a maximum reduction of cement comsumption 2 , to lower the concrete ' s hydration heat 3 , to reduce concrete ' s shrinkage and cracks , and 4 , to promote concrete ' s performance , a high quality chilled blast furnace superfine slag has been adopted as an admixture . furthermore , the adoption of some other minerals as the admixtures to get a high performance concrete has been carried out . as a result , these procedures and operations would have developed considerably the potential activity of concrete , and eventually the multiple performance and multiple function of concrete would have been improved and promoted . in conclusion a good result has been achieved in practice 文摘:首都国际机场停车楼工程中，采用c50及c60以上高性能混凝土，为最大限度减少水泥用量，降低水化热，减少收缩与裂缝，提高混凝土的性能，优选了有效成分含量高、质量好的水淬高炉矿渣磨细后单独掺用，或再与其他矿物组分复合作为高性能混凝土的掺合料，以充分发挥矿渣的潜在活性，从而使混凝土的多项性能得到极大的改善和提高，并在实际应用中取得了良好的效果。
