What is a common requirement for concrete mixes regarding temperature?

Maintain below 90°F
Maintain below 95°F
Maintain below 100°F
Maintain below 105°F

The correct answer is: Maintain below 100°F

A common requirement for concrete mixes is to maintain the temperature below 100°F. This threshold is significant because higher temperatures can negatively impact the properties of fresh concrete. When the temperature exceeds this limit, it can result in accelerated setting times, which can lead to difficulties during placement and finishing. It may also increase the risk of temperature-related problems like shrinkage cracking and reduce the overall strength and durability of the finished product. Maintaining the temperature below this level helps ensure proper hydration and allows for adequate workability, ultimately leading to a stronger and more durable concrete mix. It is essential to monitor the temperature of both the mixing water and the aggregates, as well as the ambient conditions, to ensure compliance with this requirement.
