In order to seek the creep change rules of used concrete with two different mix proportions, the test is carried out in the situation which is similar to that of the creation of concrete C60,and the creep test on the concrete of two different mix proportions is done under standard lab. Based on creep test of the high performance concrete, the creep degree and the creep coefficient are obtained. By comparing with the wide-adopted models of ACI209 (1997) and CEB-FIP MC90, it is found that the test result is good at its regularity and the research results offer reference to the calculating analysis of the on-the-spot experimental data.
