摘要

The stressed tests were performed under elevated temperature until 700 ℃. The free thermal strain and transient strain of self-compacting concrete are studied in this paper. The creep strain under 200-600 ℃ and constant load was done at high temperature. The relationship between transient strain and temperature, stress level were studied in this paper,and the function calculating the transient strain was brought forward. The mechanism of transient strain of self-compacting concrete was been studied based on the results of DTA,SEM and MIP, which offered a theory and test basis for the deformation of self-compacting concrete under high temperature.
