To study the influence of high temperature on the creep behavior of shale ceramsite lightweight aggregate concrete（SCLAC）， uniaxial compression test， multistage creep test and scanning electron microscope（SEM） test of SCLAC exposed from room temperature to 800 ℃ were carried out. The loss of mass and compressive strength， creep behavior and microstructure characteristics of SCLAC were analyzed. The results show a decrease in the mass and compressive strength and the internal microstructure becomes more loose， as the temperature rises. After 800 ℃， the loss ratio of mass and compressive strength is 9.54% and 63.88%， respectively. With higher target temperature and higher stress level， the creep strain and creep rate increase， while the creep failure threshold stress and creep duration reduce， significantly. Furthermore， the creep strain of SCLAC exhibits a considerable increase above 600 ℃ and the creep strain under the same loading ratio at 600 ℃ increases by 82.76%， compared to the creep at room temperature. Based on the test results， the Burgers creep model agrees well with the creep test data at the primary creep stage and stable creep stage.
