Abstract：
The experiment was carried out by using different concentration gradient of the aggregate exposing solvent test, and set up the concrete health environment with different temperature gradient, the concrete hydration heat test was carried out with the control group with the addition of aggregate exposing solvent. The results show that the cleaning time and the depth of EACCP is increasing with the increase of the concentration of aggregate exposing solvent, but they are not increased.,after the certain concrete, the disappearance rate of the surface water film increases with the increase of the temperature of the health environment, and the spraying time of the terring agent is shortened. The hydration heat release rate of the cement concrete of the addaggregate exposing solvent groups and unadded groups increased with the increase of the constant temperature, and the exothermic rate curves show a tendency to increase first and then decrease. However, the maximum exothermic rate, the maximum exothermic rate and the heat release rate of concrete 1 400 min were reduced and delayed of the addaggregate exposing solvent groups.
