What is the minimum slump test requirement for concrete used in standard residential foundation work in California?
Correct Answer
A) 2 to 4 inches
CBC Section 1905.7.1 typically requires concrete slump to be between 2 to 4 inches for standard foundation work. This range ensures proper workability for placement while maintaining adequate strength characteristics. Higher slumps can reduce concrete strength and durability, which is particularly important in California's diverse climate conditions.
