Abstract:The influences of curing temperature and loading age on the early age tensile creep characteristics of C60 high strength concrete were experimentally investigated. The results indicate that the creep speed, creep coefficient and specific creep show an exponential decay with the increase of loading age, and the differences of tensile creep speed at different loading ages become less when the holding time increases. The same tendencies of tensile creep speed and specific creep can be observed under different curing temperatures. It is also showed that the early age tensile specific creep decreases with the increase of temperature at the same loading age. This phenomenon is different from the effect of temperature on the tensile creep of mature concrete. But the decrease magnitude reduces with increasing loading age, and it tends to be essentially flat at loading age of 7000d. The differences of high strength concrete creep between the different loading ages decrease with the increase of curing temperature at the same holding time whenever the holding time is 7, 14d or 21d.
