Prediction of Compressive Strength of Reinforced Concrete Structural Elements by Using Combined Non-Destructive Tests

Journal of Engineering, 2023
This research is devoted to investigate relationship between both Ultrasonic Pulse Velocity and Rebound Number (Hammer Test) with cube compressive strength and also to study the effect of steel reinforcement on these relationships.

Estimation of uniaxial compressive and indirect tensile strengths of intact rock from Schmidt hammer rebound number

Journal of the Mechanical Behavior of Materials, 2023
A number of destructive and non-destructive tests were conducted on rock samples collected from various zones in northern Iraq. So far, for Iraqi rocks, few studies have correlated Schmidt hammer rebound (R) with both unconfined compressive strength (UCS)

Compressive Strength Prediction Model of High Strength Concrete by Destructive and Nondestructive Technique [PDF]

E3S Web of Conferences
Concrete’s compressive strength can be tested in a laboratory before construction begins. Since concrete is a natural material and cannot be destroyed, it is not possible to determine its compressive strength through destructive testing.

Assessment of Strength Development at Hardened Stage on High-Strength Concrete Using NDT

Applied Sciences, 2020
This study proposes model formulae for predicting the strength of concrete by analyzing the relationships between the results of nondestructive testing (NDT) methods and the compressive strength of concrete specimens at the hardened stage.
