What is the maximum temperature increase allowed per hour for concrete after the initial set?

In the context of concrete curing, it is critical to control the temperature increase to prevent thermal cracking and ensure the integrity of the concrete. The maximum temperature increase allowed per hour for concrete after the initial set is recognized as 36 degrees Fahrenheit. This limit helps to minimize the risk of temperature differentials that can occur between the surface and the interior of the concrete, which could lead to cracking due to restrained shrinkage or expansion.

Understanding the significance of maintaining proper temperature controls is essential for construction practices, especially in varying environmental conditions. While temperature increases greater than this threshold can compromise the quality and performance of the concrete, adhering to the specified limit aids in achieving the desired strength and longevity of the material.
