Creep Behavior of Early-Age Concrete Made with Different Cement Compositions under the Controlled Temperature History

A temperature stress testing machine (TSTM) was used to investigate effect of cement composition on cracking sensitivity and creep behavior of concrete. Results show that the cracking sensitivity of concrete varied with the ratio of C3S/C2S and it is observed that the temperature difference of concrete linearly increased with smaller ratio of C3S/C2S. Furthermore, it is also found that concrete with higher ratio of C3S/C2S had weaker creep behavior based on the specific creep deduced from results of TSTM.
