Machine learning prediction of concrete compressive strength …
In practice, compressive strength is the most assessed mechanical property to determine the onsite strength of concrete. Compressive strength is often measured on extracted core samples along with the rebound hammer and/or ultrasonic pulse velocity (UPV) tests, which are used to indirectly assess concrete strength [[4], [5], [6]].
