“…Another procedure known as the Stoll tork test (Stoll, 1985), was proposed later on in order to improve upon the variability of the existing similar techniques and to allow for testing at deeper depths than the pull-out, the pull-off and the penetration A further test procedure for precast concrete quality control purposes has been used in the former Soviet Union, as discussed by Leshchinsky et al (1990). However, this technique has not become an established international method for testing.…”

This paper provides an overview of the existing literature on the subject of Ground-Penetrating Radar (GPR) methods for the investigation of reinforced concrete structures. An overview of the use of concrete and reinforced concrete in civil engineering infrastructures is given. A review of the main destructive and non-destructive testing (NDT) methods in the field is presented, and an increase in the use of GPR to reinforced concrete structures is highlighted. It was also observed that research in some application areas has been predominantly or exclusively carried out at a laboratory scale, and that similarly, other more application-oriented research has been developed only on real-life structures. The effectiveness of GPR in these areas is demonstrated. Furthermore, a case study is presented on a new methodological and data processing approach for the assessment of reinforced concrete structures using a high-frequency dual-polarised antenna system. Results have proven the advantages of using the proposed methodology and GPR system in order to improve the detectability of rebars, including secondary bottom lines of reinforcement. The horizontal polarisation was proven to be more stable compared to the vertical. Finally, it has been demonstrated that a more accurate location of the rebars in a high-density grid mesh arrangement can be obtained by means of data migration processing with a scan spacing of 5 cm and wave velocity information through the use of the hyperbola fitting method from at least the 30% of targets.

Within-test variability of some non-destructive methods for concrete strength determination

Abstract: Experimental investigations of within-test variability of non-destructive methods to determine concrete strength are reported. Rebound, indentation, ultrasonic (with direct and surface transmissions) and shearing rib methods were among those studied.
