Which item is not typically documented on a batch ticket for ready-mixed concrete?

• A. Weather conditions
• B. Delivery time
• C. Batch weights
• D. Additives

Answer: (D)

Batch tickets are records of what was batched and delivered, focusing on data that directly ties to the concrete’s production, timing, and basic proportions. Weather conditions matter because temperature, humidity, and wind can affect mixing, setting, and placement. Delivery time is recorded to confirm the concrete arrived within the required window and to ensure it can be placed before it starts to set. Batch weights are essential to verify the proportions of cement, aggregates, water, and other materials match the approved mix design and to provide traceability.

Additives, while part of the mix, are typically controlled by the mix design and documented in separate admixture records or the plant’s mix-design documentation rather than on the batch ticket itself. Keeping detailed additive dosages out of the ticket helps avoid clutter and ensures the admixture details remain aligned with the formal mix design and project records. Some tickets may note that an admixture was used, but the precise dosages and types are usually maintained elsewhere rather than on the batch ticket.
