The tensile creep tests were performed in an experimental
setup developed by Altoubat [5] based on a setup by
Kovler [7]. The setup operates with two dog bone-shaped
concrete specimens, one of which is unloaded while the
other is loaded. Two linear voltage displacement transducers
(LVDT) are recording the axial deformation of both specimens.
The creep strain is obtained as the difference between
the deformations of the specimens. The gauge length is
626.25 mm and the side length of the quadratic crosssection
is 76.20 mm.
The setup was developed to investigate the early-age creep
behavior of fully restrained concrete subject to drying. In this
paper, the creep response due to a constant load is investigated.
The mix designs are identical to those used by Altoubat
[5] on the drying creep behavior of fully restrained concrete.
