The effects of CaO-based and MgO-based expansive additives on the mechanical， deformation properties and basic creep of C60 self-compacting concrete were studied， and the test results of creep were compared with the calculation results of the fib 2010 model. The results show that the incorporation of 6% CaO-based expansive additive and 6%， 10% CaO/MgO composite expansive additives has little effect on the compressive strength and elastic modulus of C60 self-compacting concrete， but significantly reduces the autogenous shrinkage and increases the basic creep. The concrete creep compliance and creep coefficient basically increase with the increase of the total amount of expansive additives and the increase of CaO-based expansive additive. Under the low content of CaO-based expansive additive， the test results of creep compliance of concrete are in good agreement with the calculation results of fib 2010 model， but under the condition of high content of CaO-based expansive additive， the development trend of concrete creep is significantly higher than that of the calculation results. When mixing with MgO， the creep further increases with the increase of load holding duration. For the concrete incorporating high content of CaO-based and MgO-based expansive additive， it is necessary to study the influence of expansion on the development of creep with time， and then to modify the model.
