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.

Evaluation of Building Structural Stability by Using Rebound Hammer Test
International Journal of Scientific Research and Engineering Trends-The quality problems encountered in concrete structures appear at different stages of the construction of works, It is for this reason that for a long time there has been an increased demand for more precise and, at the same time, more flexible methods ...

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 ...

Adapting ANFIS to Improve Field Rebound Hammer Test for Concrete Compressive Strength Estimation
Materials Science Forum, 2020Rebound hammer tests are one of the most popular non-destructive testing methods to examine the concrete compressive strength in the field. Rebound hammer tests are relatively easy to conduct and low cost.

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 ...
