Abstract

The In this study, the change of composition of the hydrates according to the recovery age of concrete in the case of fire damage was confirmed through microscopic analysis. In 28 days of age, the production of ettringite was higher than that of day 1, and the calcium hydroxide was increased in the 91 day. It has been recovered through the generation of major hydrates which affect the strength.
