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.

Tensile creep of concrete at early ages is one of the important factors that affect the stress of restrained and partly restrained concrete. But only few data are available on tensile creep of concrete. The effect of ground slag on tensile creep was studied using lever-type tensile creep tester. Early age tensile basic creep of concrete loaded at the age of 3 days was researched. Results show that concrete exhibits large creep deformation when loaded at the age of 3 days. And the addition of ground slag decreases the early age tensile creep of concrete and tensile creep of concrete decreases with the increase of the content of ground slag. But the basic rule of the development of basic tensile creep in concrete has not been changed.
