Identified as 02-7099 corresponds to which parameter?

• A. Concrete Mix Design Number
• B. Moisture Content
• C. Fly Ash Certification
• D. Chloride Test Results

Answer: (A)

Concrete mix design numbers are the identifier for the exact recipe approved for use on a project. A number like 02-7099 uniquely references a specific mix design, which links to the documented proportions and materials (cement content, aggregates, water-cement ratio, admixtures, air content, slump, etc.). The inspector uses this number to verify that the concrete being delivered matches the approved design, not to read a measured value or a test result. It isn’t moisture content (that would be a percentage), nor a fly ash certification, nor a chloride test result. Verifying that the batch ticket and project records show the same mix design number confirms compliance with the approved mix.
