Evaluation of schmidt rebound hammer testing: A critical approach
Bulletin of the International Association of Engineering Geology, 1993In the present paper, a critical approach to the evaluation of Schmidt hammer testing is attempted. Through a statistical analysis of field measurements on sandstone blocks from the archaeological site of Delphi (Greece), it was shown that there is an inconsistency in the correction method proposed by the manufacturer, in relation to the direction of ...

Rebound hammer test to estimate compressive strength of heat exposed concrete
Construction and Building Materials, 2018Abstract The residual concrete strength is required for evaluating the safety of reinforced concrete structures after fire. Based on the surface hardness of concrete, a rebound hammer test has been used to evaluate the compressive strength at the ambient temperature and after fire.

Construction and Building Materials, 2018
Abstract The spatial variability of the mechanical properties of concrete is an important characteristic, which plays an important role in the stochastic analysis of the concrete structures, especially in the reliability analysis. Two categories of experiments named non-destructive testing (NDT) and destructive testing (DT) are used for the ...

High-strength concrete – NDT with rebound hammer: influence of aggregate on test results
Nondestructive Testing and Evaluation, 2014Rebound hammer is the most frequently used non-destructive method for estimation of concrete strength. Measurement results are influenced by various factors (components and composition of concrete, humidity or age), which are well known for normal-weight concrete. High-strength concrete (HSC) differs in quality and the question is to which extent these

Testing of SFRC by the Schmidt Rebound Hammer
MRS Proceedings, 1990AbstractThe rebound number, its relationship to fundamental frequency and correlations with compressive strength and erosion - abrasion resistance are discussed. Nine mix proportions were used. The w/c ratios were varied from 0.30 to 0.65. The volumetric percentage of hooked steel fibres was varied from 0.25 to 2.0 vol.% at the w/c of 0.30; at the ...

Applying Support Vector Machines in Rebound Hammer Test
Advanced Materials Research, 2013There are several nondestructive testing techniques available to test the compressive strength of the concrete and the Rebound Hammer Test is among one of the fast and economical methods. Nevertheless, it is found that the prediction results from Rebound Hammer Test are not satisfying (over 20% mean absolute percentage error).

Evaluation of Schmidt Hammer Rebound Hardness Test Holders
Geotechnical Testing Journal, 1984Abstract An evaluation is made of three different holders for Schmidt hammer tests on rock core in the laboratory, including steel angle, V-notch, and semicircular groove holders. The differences are small, but it is shown that the V-notch holder gives consistently higher rebound hardness values.
