Abstract:: In this paper，the axial compressive strain—stress cHrve of plastic concrete is tested．On the basis ofthe experimental results，and comparison study of the calculating method of the elastic modulus of plain COIl—crete，It is put off that the slope from 0．3 times peak stress to 0．6 times peak stress is more stable in the upward section of axial compressive strain—stress curve of plastic concrete．Therefor，befitting calculating methodof the elastic modulus of plastic concrete has been gained．
