適用范圍：This part of ISO 1920 specifies non-destructive test methods for use on hardened concrete. The methods included are a) determination of rebound number, b) determination of ultrasonic pulse velocity, and c) determination of pull-out force. NOTE These test methods are not intended to be an alternative for the determination of compressive strength of concrete, but with suitable correlations they can provide an estimate of in-situ strength.
