摘?要:分析了混凝土拌合物流變特性的影響因素,探討了混凝土泵送流動行為及剪切變稀和泵送損失的機理,并試圖利用混凝土的流變特性對其施工性能尤其是超高泵送性能進行分析評價。施工現場數據表明,采用塑性黏度和屈服應力對泵送沿程壓力損失進行評估是可行的,能夠指導類似工程施工。Abstract:Thefactorsofaffectingtherheologicalbehaviorofconcreteisanalyzed,themechanismofconcretepumpingflowbehaviorandshearthinningandperformancedeteriorationduetopumpingarediscusse,andtheconstructionperformanceofconcreteespeciallysuperhighpumpingperformanceisanalyzedbasedontherheologicalbehavior.Bycomparingandanalyzingtheactualengineeringtestdata,itisfeasibletoevaluatethepumpingpressurelossbyusingplasticviscosityandyieldstress.
