Abstract
The paper presents overview of European standard procedures related to determining concrete quality basing on the in-situ testing. Among other things following testing methods have been discussed: testing cored specimens, rebound measurements, “pull-out” method, “pull-off” method, ultrasonic pulse velocity measurements. Testing conditions, guidelines for calibration and crucial requirement for proper interpretation of the data obtained by means of rebound and ultrasonic measurements were shown. Independently “pull-out” and “pull-off” NDT methods have been introduced. Finally, the European procedures of assessment of in-situ concrete compressive strength in structures have been also presented.
Highlights
During last decade in EU countries several major changes were introduced regarding the legal status of concrete quality assessment
The mile stone of changing engineering practice in this aspect was introduction of European Standard EN-206-1 [1] which is mainly focussed on the conditions ensuring durability of concrete
Complement the hole of this subject is European standard specified as EN-13791 [4], which provides procedures for proper testing data interpretation and assessment of the insitu compressive strength of concrete in structures and precast concrete components
