Final answer:
The maximum slump for lightweight concrete is typically 4 - 6 inches.
Step-by-step explanation:
The maximum slump for lightweight concrete is typically 4 - 6 inches. Slump refers to the measure of the consistency or workability of the concrete. A higher slump means the concrete is more fluid and easier to pour and shape. For lightweight concrete, a larger slump is generally allowed to compensate for the reduced density and ease of handling.
