Effect of treatment temperature on the early hydration ...
The increase of the treatment temperatures (35 and 55 °C) leads to an increase in the height of electrical conductivity peaks of superplasticized cement pastes. This is due to the increase of the paste fluidity due to the change of the adsorption capacity of the superplasticizer, as mentioned before [15].

The effect of elevated temperatures on the weight loss of the concrete specimens is shown in Fig. 3.It increased with temperature increase. These losses were about 5% and 45% after subjecting to 200 and 1200 °C, respectively.The reduction in weight gradually increased up to 800 °C, however, there was a sharp jump in loss in weight loss beyond 800 °C.

Effect of High Temperatures on Concrete| Concrete ...
High temperatures also affect the compressive strength of concrete. Above 212º F, the cement paste begins to dehydrate (loses chemically combined water of hydration), which gradually weakens the paste and paste-aggregate bond. The temperature that concrete has reached often can be determined by observing color changes in the aggregate.
