Five year drying of high performance concretes: Effect of temperature and cement-type on shrinkage

Subsequently, relative mass variation (RMV) is plotted against shrinkage εshdry data. Three distinct phases are obtained at 20 or 50°C and down to 30%RH; up to four distinct phases are observed at T = 80°C and down to 12%RH. The latter are confirmed by experiments on (60°C; 7%RH) dried concrete. The four phases in the (RMV,εshdry) diagram are interpreted against shrinkage data on mature cement paste dried at 60°C; 7%RH and against the literature.
