The tensile creep behavior is extremely important in crack prediction and stress analysis of concrete. The main objective is investigating the effects of the silica fume on the tensile basic creep of early-aged concrete. The effect of silica fume on tensile creep was studied using lever-type tensile creep tester. Silica fume amount by weight of total cementing material was 0%, 5%, 10% and 15%. Results show that concrete exhibits larger tensile basic creep strain if loaded at early age. The development characteristic of tensile basic creep of concrete with different silica fume content is that development rate is relatively fast after loading 12h, and slowes down gradually after loading 12h. The early age tensile basic creep of concrete increases with the increasing of the content of silica fume.
