Abstract：
The elastic modulus of fly ash, cement and slag of two varieties were tested by nano-indentation technique with mortar creep degree as the goal, experimental design for elastic modulus of cementitious materials, cementitious materials elastic modulus on the creep properties of cement-based materials influence. The results show that the elastic modulus of cementitious material has a great influence on the creep degree of mortar. Change the elastic modulus of the slag, the specimens 360 days creep amplitude reached to 34.4%. The mechanical properties of the mortar specimens with high modulus of elasticity are better than those of the mortar. In practical applications, considering the creep properties, the influence of the factors such as strength should be considered.
