Abstract
This paper presents the results of crack creep tests on three dam models (240 cm high) made with three types of concrete, with maximum aggregate size Φ equal to 3.15, 12 and 25 mm. In order to characterize the material a series of tensile tests was performed for each kind of concrete. In this way the static parameters (Young’s modulusE, ultimate tensile strength σu, compressive strength σc, fracture energyGF) and creep laws were obtained.
