  • Mechanical properties of concrete at high temperature—A

    2015/09/15· Abstract. High temperature is well known for seriously damaging concrete micro- and meso-structure, which brings in a generalised mechanical decay of the concrete and even detrimental effects at the structural level, due to concrete spalling and bar exposure to the flames, in case of fire. Because of the relevance of concrete behaviour at high

  • Effect of High Temperatures on Concrete| Concrete

    1999/12/01· 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.
