Calibration of Rebound Hardness Numbers to Unconfined Compressive Strength in Shale Formations

Journal of Petroleum Technology, 2015
Young Technology Showcase Today, unconventional-reservoir characterization is actively studied; however, rock-mechanics tests are still restricted to intact rocks. Intact intervals are necessary to acquire plug specimens (Fig. 1a).

QUANTITATIVE EVALUATION of the FACTORS AFFECTING the SCHMİDT REBOUND NUMBER

2023
The Schmidt hammer provides a quick and inexpensive measure of surface hardness that is commonly used for predicting the mechanical properties of rock material. Surface roughness, water content of the test sample, weathering, Schmidt hammer type, the testing methods and influence of grain size are important parameters affecting the Schmidt hammer ...

Application of Schmidt rebound number for estimating rock strength under specific geological conditions

2010
A literature review revealed that most of the empirical equations introduced for determination of the uniaxial compressive strength (UCS) of rocks based on the Schmidt hammer rebound number (N) are not sufficiently reliable mostly due to the relatively low coefficient of correlations.

Predicting Concrete Compressive Strength Using Ultrasonic Pulse Velocity and Rebound Number

ACI Materials Journal, 2011
This paper shows how, as a general index of concrete strength, the compressive strength of concrete f(c) is important in the performance assessment of existing reinforced concrete (RC) structures. The paper shows how many nondestructive testing methods have been developed to estimate the in-place value of f(c). In particular, the combination of rebound
