Temperature plays a critical role in the curing, strength development, and durability of concrete. High temperatures can accelerate the hydration process of cement, leading to faster strength gain in the initial stages but potentially resulting in lower ultimate strength and increased risk of cracking due to rapid moisture loss and thermal gradients within the concrete. Conversely, low temperatures slow down the hydration process, significantly delaying setting and strength development, which can be detrimental in time-sensitive construction projects. Temperature variations can also lead to thermal expansion and contraction in hardened concrete, potentially causing cracks if the changes are rapid and severe.
