Florida DOT Concrete Batchman/Operator Practice Exam

Which piece of information is NOT required when filling out the aggregates on the delivery ticket?

1. The type of aggregate used

2. The target weight of the aggregate batched

3. The moisture content of the aggregate

4. The specific gravity of the aggregate

The correct answer is: The target weight of the aggregate batched

When filling out the aggregates on the delivery ticket, the target weight of the aggregate batched is not typically required information. The delivery ticket serves as a record of the materials delivered for a concrete mix, and while it is essential to document the type of aggregate used, its moisture content, and sometimes its specific gravity for quality control purposes, the target weight is often determined during the batching process based on the required concrete mix design rather than needing to be noted on the ticket. The type of aggregate used is crucial for understanding the characteristics of the concrete. Knowing the moisture content is vital as it affects the water-to-cement ratio, and specific gravity provides insights into the aggregate's density, aiding in mix design calculations. However, the target weight is more of an operational detail that may vary based on the specific batch and isn’t typically documented on delivery tickets for review.
