Which of the following is a typical method to ensure quality control on a concrete pour?

• A. Pre-pour checks, slump tests, cylinder sampling, and batch-ticket verification
• B. Only slump tests
• C. Curing time and temperature monitoring
• D. Surface density measurement

Answer: (A)

Quality control on a concrete pour is best achieved by a coordinated set of checks that cover materials, workability, strength verification, and proper documentation. Pre-pour checks ensure the forms, reinforcement, joints, and equipment are ready and that the batch is prepared to spec. A slump test evaluates the fresh concrete’s workability and consistency, catching mix issues before placement. Cylinder sampling provides specimens to test for compressive strength later, confirming the mix will meet structural requirements. Verifying batch tickets ensures the concrete delivered matches the approved mix design, quantities, and supplier certifications, adding traceability and accountability. Together, these steps address both how the concrete is prepared and how its performance will be verified, whereas relying on only one measure like a slump test misses other critical aspects; curing-time monitoring alone doesn’t verify material quality, and surface density measurement isn’t a standard QC parameter for concrete pours.
