Which statement describes what should be visible at the job site to identify a ready-mixed concrete delivery?

• A. Delivery ticket or mix design information visible, project numbers, strength/class, slump, air content, temperature, and batch time.
• B. The driver's name only.
• C. The truck's color.
• D. The weather forecast.

Answer: (A)

What matters at the job site is having the delivery ticket or mix design information clearly visible, because this document ties the concrete to the exact order and specifies the required properties. It shows project numbers, the designated strength or class, and the fresh-concrete parameters that affect performance and placement: slump for workability, air content for durability and freeze-thaw performance, concrete temperature for proper curing and control of setting, and the batch time to confirm the concrete is fresh and within the allowable placement window. This documentation provides the verification needed to ensure the delivered concrete matches the specified mix design and is ready for placement. Relying on a driver’s name, truck color, or a weather forecast does not verify the mix design, properties, or timing required for proper use.
