摘要
Abstract
This paper studied different fly ash (30% -80%)of hydraulic concrete experiment and summarized hydraulic concrete creep per-formance factors,such as fly ash,loading age,load holding duration etc. It had been compared and analyzed concrete creep prediction mod-el at home and abroad by experimental research,and been found that the range trend of B3 model was consistent with the test,but the pre-dicted values were higher than that of the measured. However,the predicted values of Zhubofang model were close to the test results. There-fore,this study suggested that these two models should be combined to estimate the degree of creep in actual project.关键词
