compacting properties 中文意思是什麼
-
The binders has supper fluidness 、 bonding capacity 、 water retentivity 、 filler properties, no segregation, no bleeding and supper mechanical properties after harden. it is one of high performance concrete. japanese have been researched self - compacting concrete from 1987, and used more than 1. 2millions litres
其拌和物具有良好的流動性、粘聚性和保水性，要求填充性能優異，不離析、不泌水且硬化后具有良好的力學性能，屬于高性能混凝土（ high - performanceconcrete ）的一種。 -
The effect of compacting on the engineering properties of loess
擠密對黃土工程特性的影響 -
Experimental study of mechanical properties of self - compacting lightweight aggregate concrete
自密實輕骨料混凝土力學性能試驗研究 -
On the base of experimental results of self - compacting capability and mechanical properties, the self - compacting concrete is proved to be used in trc
結果表明：這種自密實混凝土具有良好的工作性能和力學性能，完全可以用來作為纖維編織網增強混凝土的基體。 -
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。
