What is the primary purpose of batch-ticket verification in QC for concrete pours?

• A. To verify that the pour uses the correct mix design and material quantities
• B. To check color consistency
• C. To measure air content
• D. To calculate yield

Answer: (A)

Ensuring the batch ticket matches the approved mix design and material quantities is the essential point. The batch ticket is the documented record of what was planned and what was delivered for that pour, listing the exact proportions and components—cement content, aggregates, water, admixtures, and the total quantity. Verifying it confirms the concrete being placed will have the intended properties (strength, workability, durability) because those properties come from the specified mix design and material amounts. If the ticket doesn’t align with the approved design, the concrete could end up with the wrong water‑cement ratio or incompatible materials, compromising performance.

Color consistency is a cosmetic concern and not a measure of structural quality. Air content and yield are important QC checks in different contexts—air content is tested on the fresh mix, and yield relates to estimating concrete volume produced—not the primary purpose of checking the batch ticket against the design and quantities.
