If fresh-concrete tests show results outside the specified limits, what action should the inspector take?

• A. Continue placement and disregard the tests.
• B. Notify the engineer and document test results, pursue corrective actions per FDOT procedures.
• C. Re-test only if time allows.
• D. Retest only after a full shift.

Answer: (B)

When fresh-concrete test results fall outside the specified limits, stop placement, immediately notify the engineer, and document the test results, then pursue the prescribed corrective actions per FDOT procedures. This ensures any potential issues with the mix—such as workability, air content, temperature, or consistency—are addressed before further placement, protecting strength, durability, and constructability. The engineer will direct the appropriate actions, which may include mix adjustments, retempering, re batching, or removal and replacement. Continuing without addressing the out-of-spec results or delaying action until later does not meet quality control requirements.
