cone rheometer
解釋
錐形流變儀-
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。 -
Cone - based rheometer was modified to estimate the rheological properties of fresh mortar, which can measure yield stress and plastic viscosity of mortar in relative units. effects of many factors on rheological properties of mortar were studied. a set of test theory and method for designing rheological properties of mortar was recommended
用它研究了各種因素對砂漿流變性的影響；證實了砂漿的屈服應力與塑性粘度是互相獨立的物理量，屈服應力決定變形能力，塑性粘度決定變形速率；為砂漿流變性設計提供了一套測試理論和方法。
