2 cards from this section. Quick, good the night before a test.
What is a correlation in terms of concrete testing?
Think about how lab results can reflect on the site performance.
Define acceptance criteria.
These standards are tied to lab test results.
What is the main purpose of correlating field test results with lab results?
Think about what could happen if low quality is used.
True or False: Acceptance criteria allow for any variation without limits.
Recall the restrictions set for acceptance.
A construction project has field results of 28 MPa for the concrete mix, while the lab tests indicated a result of 30 MPa. What should be the next steps?
Think about quality control and monitoring steps.
If a lab's acceptable tolerance for concrete strength is ± 3 MPa, and the lab result is 25 MPa, what are the possible field test results for acceptance?
Use a simple subtraction and addition strategy around the given lab result.
