What is the purpose of maintaining records of pad usage?

Maintaining records of pad usage is crucial for monitoring signs of wear and testing quality. Pads are essential components of concrete testing equipment, specifically in compressive strength testing where they are used under the test specimen to distribute the load evenly during the test. By keeping track of how often pads are used, technicians can assess their condition and effectiveness. Over time, pads can wear down, which may affect the accuracy of test results. Regular tracking helps to identify when pads need replacement, ensuring that testing remains reliable and compliant with standards. Keeping these records supports the overall integrity of the testing process and ensures that accurate strength assessments of concrete are performed.
