Effect of High Temperatures on Concrete
01.12.1999High temperatures also affect the compressive strength of concrete. Above 212 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
