Abstract: 
The post-installation of reinforcing bars at low ambient temperatures may increase the creep rate and decrease the strength. The relationship between a low curing temperature and the shortterm and long-term capacity has not been investigated in detail yet. In a first step tests employing an epoxy based mortar were carried out to investigate the creep behavior under various temperatures at the time of curing, sustained loading and pullout to achieve a better understanding of the effects caused by reduced hardening and incipient post-curing. The tested product was sensitive to decreased installation temperatures: While the pullout strength was influenced only when tested at higher temperatures, the creep displacement became excessive already when conducted at moderate temperatures.
