Abstract

In this study, as part of the study to reduce and integrate heat of hydration of concrete, the performance change of super retarding agent is examined in the mortar area under high temperature conditions. It was confirmed that the setting time delay can be adjusted from several hours to several days depending on the high temperature and the change of super retarding agent mixing rate. With the increase of super retarding agents, the early age strength was delayed while at 28 days the use of super retarding agent results in an increase of strength remakably.
