| Abstract: | A study was made on concrete creep under different curing temperatures, and the comprehensive effects of time and temperature on creep development were expressed with the chemical reaction rate. By regression analysis of experimental data with the least square method, the relationship between curing temperature and concrete creep was discussed, and formulas for the elastic modulus and specific creep of concrete expressed with equivalent time were put forward. |

| Keywords: | concrete specific creep equivalent time least square regression method back analysis |
