Abstract :
This paper focus on the behavior of autogenous shrinkage of high strength/performance concrete with water cement ratio of 0.3 and slump flow of 500mm based on the experiment under 4 different curing temperatures (10°C, 20°C, 28°C, 35°C). The influence of curing temperature on autogenous shrinkage strain and strain rate was discussed; the usability of evaluation on the influence of curing temperature based on the concept of equivalent age was investigated. The results showed that the amount and rate of autogenous shrinkage strain both increase with the rising of curing temperature; the equivalent age has a better applicability to evaluating the influence of curing temperature on autogenous shrinkage of HSC/HPC which is cured in higher temperature than in lower temperature.
