What is the maximum slump allowed for concrete placed in removable forms?

3 inches
4 inches
6 inches
8 inches

The correct answer is: 6 inches

The correct answer indicates that the maximum slump allowed for concrete placed in removable forms is 6 inches. This measurement is crucial because slump tests are a standard way to gauge the workability of concrete. A slump of 6 inches is typically acceptable for most constructions where concrete needs to flow into forms and fill spaces adequately without segregation or excessive bleeding. In the context of using removable forms, maintaining an appropriate slump means ensuring that the concrete can be positioned effectively while still retaining the necessary strength and cohesion once it sets. A slump exceeding this maximum could lead to durability concerns, such as cracking and segregation of the aggregate, which ultimately affects the integrity of the structure. By adhering to the specified maximum slump, contractors can ensure that the concrete maintains a balance between fluidity for placement and sufficient stiffness to hold its shape once cured, ensuring the longevity and safety of the construction.
