When testing concrete for slump according to California standards, what is the acceptable slump range for most structural concrete applications?
Correct Answer
D) 3 to 6 inches
California Test Method 533 and CBC requirements typically specify a slump range of 3 to 6 inches for most structural concrete applications. This range provides adequate workability for proper placement and consolidation while maintaining the concrete's strength properties. Lower slumps may cause placement difficulties, while higher slumps can compromise strength and durability.
