| 要旨 | This paper reports the results of an experimental investigation on the effect of silica fume content on creep and shrinkage behavior of high-strength concrete. Besides the control mix, three mixes incorporating silica fume as 5%, 10%, and 15% of the total cementitious materials (cement + silica fume), were prepared. Test specimens were dried and loaded at ages of 3, 7, and 14 days after casting. After preparation and load application, the specimens were transferred to two separate environmental rooms with 60% and 80% RH. According to this investigation, it is clear that the existence of silica fume considerably reduces the shrinkage strain and creep coefficient values. |
