Abstract
This article outlines an experimental and numerical study of the short-term creep of High-Performance Concrete, HPC, with sealed curing and temperature under freezing point, which is compared with the creep of HPC at normal and elevated temperatures. For this purpose one quality of HPC was studied at 6 different temperatures (-15, -1, 20, 30, 40 and 60 °C) over a period of 66 hours. Parallel studies of both autogenous and drying long-term creep after heat curing were carried out. New and original results and analyses of the effect of temperature as regards compressive creep of HPC are pre-sented. At -1 °C in the concrete, a loading level as low as 25% of the ultimate loading was needed to perform the creep tests properly. At -15 °C HPC withstood at least 43% of the ultimate loading during creep test. The study was carried out from 1992 to 1994.
