| Abstract: | The paper invent a novel apparatus which is used to measure the thermal dilation coefficient(TDC) of concrete at early-age.And the TDC of different concrete are measured from the time of initial setting.Then the development regularity of concrete TDC at early-age is summed up and the prediction formula is put up for the concrete TDC at early-age. |
