When a batch ticket shows added water after batching, what must the inspector verify?

• A. That water addition is within the allowable proportion per the mix design, is properly recorded on the ticket, and approved by the plant and contract.
• B. Water added with no record and no approval
• C. The water taste and color
• D. The batch ticket remains unchanged

Answer: (A)

The main idea is that any water added after batching must be controlled and properly documented to keep the mix within its approved specifications. Water added after batching changes the water-cement ratio, which affects strength, durability, and workability, so it must be verified against the mix design limits and the project’s approval process. The best answer requires three checks: that the additional water stays within what the mix design allows, that the change is recorded on the batch ticket, and that both the plant and the contract have approved the adjustment. This ensures traceability, accountability, and compliance with contractual and spec requirements. Unrecorded or unapproved water is not acceptable, since it bypasses the official change process. Water’s taste or color is not a reliable or acceptable method for verifying adjustments, and leaving the batch ticket unchanged would misrepresent the actual batch.
