Specimens

The SFRSCC specimens used for assessing the creep behaviour in cracked conditions were extracted from a panel with 1.5 x 1.5 m2 in plan and 0.06 m of thickness. The panel was cast from its geometric centre. A total of one hundred and twelve specimens with the dimensions of 0.24 x 0.06 x 0.06 m3 were extracted from distinct locations. The specimen’s notch depth and thickness were 10 and 2 mm, respectively. The orientation of the extracted prismatic specimens within the panel was established having in mind the expected concrete flow direction, see Fig. 1, considering P as the angle between the direction of the concrete flow and the notched plane direction. Four intervals with different P were defined, i.e. [0—15°[, [15-45°[, [45-75°[ and [75-90°]. In Fig. 1a, the light grey solid hatched specimens were used for assessing the long-term behaviour, whereas the rest were tested under instantaneous monotonic load conditions at the same age of the specimens cracked for the creep test program.
