Testing Slump in Your Concrete Mix and Why It Is Important ...

08-10-2004  However you define it, though, the bottom line remains the same: Slump is a test for the rigidity of uncured concrete. Lower slump concrete is very stiff, and higher slump concrete is more fluid. Most people in the business agree that a typical slump for ordinary decorative concrete applications would be in the 4- to 5-inch range, but there’s no hard-and-fast rule.
