【Abstract】 Three repair materials were tested for their behavior of tensile creep. The mathematical model of tensile creep for repair materials was established based on a three element model. From the test results and the mathematical model, the factors of the tensile creep model, the early tensile creep and the relaxation modulus of repair materials were determined. A comparison shows that the theoretical values based on the model tally with the test results.更多还原
