This study deals with autogenous restrained deformation of cement pastes at early age in controlled-temperature conditions. Two water-to-cement ratios (W/C = 0.3 and 0.4) and three curing temperatures (T = 20, 30 and 40°C) are investigated. The measurement method for restrained shrinkage is the ring-test method. The experimental device is equipped with a peripheral water circulation system to keep the specimen in quasi-isothermal conditions. The results show that the curing temperature significantly influences the appearance of the first cracking. Furthermore, the decrease of the water-to-cement ratio and the increase of the ring rigidity cause a diminution of the cracking age.Cet article présente une étude sur le retrait endogène empêché d...
