What is the maximum rate of pour allowed for a wall over 14 feet in height, according to ACI standards?

According to ACI (American Concrete Institute) standards, the maximum rate of pour for concrete walls over 14 feet in height is set at 15 feet per hour. This guideline is in place to ensure the quality and integrity of the concrete when it is poured at greater heights. Pouring at this rate allows for adequate time for the concrete to settle and minimizes the risk of defects, such as cold joints or improper curing, which can compromise the structure's durability and strength.

The regulations are designed with safety and performance in mind, emphasizing that when working with taller walls, controlled pouring rates contribute to better workability and overall construction quality. It’s essential for contractors to be aware of these standards to maintain compliance and ensure the longevity of their structures.
