Vibration durability test
振動耐久性試驗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。Measures for further developing concrete mix design were presented based on above work. for example, adopts pfca as an index in designing durability of concrete, uses mortar slump flow test to select cements and water - reducers and to measure saturation dosage of water - reducer in mortar and then determine optimum dosage of it in concrete, uses bar - slump test to determine stability and fluidity of fresh concrete, and consequently, the workability of high fluidity and high stability concrete such as pumped or self - compacting concrete can be designed by adopting proper cfvm determined in terms of rheological properties of designed mortar measured with cone - based rheometer
如採用粗集料破碎率作為耐久性設計的一個指標；採用砂漿坍落擴展度試驗選擇水泥和減水劑，確定砂漿中減水劑的飽和摻量，並通過上述數學模計算混凝土中減水劑的飽和摻量，以此為參照確定最佳摻量；採用障礙坍落度試驗確混凝土的穩定性和流動性，結合由漏斗式砂漿流變儀測定的砂漿流變性能確定合理的砂漿填充系數，從而實現對高流動性高穩定性要求的混凝土（如泵送和免振自密實等）的工作性設計。
