The slump of concrete placed in removable forms shall not exceed how many inches?

The correct answer is six inches because this measurement is commonly established in construction standards for the consistency and workability of concrete. A slump of six inches is typically the maximum allowable for concrete that will be placed in removable forms. This limit ensures that the concrete retains sufficient stability and does not become too fluid, reducing the risk of segregation or excessive settling when the forms are removed.

Maintaining a controlled slump is crucial for achieving the desired structural integrity and performance of the concrete. It allows for ease of placement while still providing the necessary characteristics for the material as it cures. A slump above this measurement could lead to challenges, such as difficulty in forming and finishing, and may compromise the overall quality of the concrete work.
