Question: 1 / 400

Why is monitoring the temperature during curing important?

To prevent overheating

To ensure proper hydration and strength development

Monitoring the temperature during curing is crucial because temperature affects hydration and strength development in concrete. Proper hydration is necessary for the hydration reactions that strength gain in concrete relies upon. If the temperature is too low, these reactions can slow down significantly, leading to incomplete hydration and resulting in lower final strength. Conversely, if the temperature is too high, it can accelerate the reactions too quickly, leading to potential problems such as cracking and reduced long-term durability. Maintaining the appropriate temperature during the curing phase ensures optimal hydration conditions, allowing the concrete to develop its intended strength and structural performance. This is why ensuring proper hydration and strength development is the most critical aspect of temperature monitoring during the curing process.
