DESCRIPTION

This CCPA standard is developed to standardize the application of the impact elastic wave method for detecting grouting compactness in prestressed conduits, ensuring the scientific validity and reliability of test results.

This CCPA standard is applicable to the assessment of grouting compactness in conduits of bonded prestressed structures constructed using the post-tensioning method, utilizing the impact elastic wave technique.
