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.

This manuscript investigate the quality of concrete using non-destructive in-situ testing.The in-situ testing is a process by which different test are carried out such as rebound hammer, ultrasonic pulse veloc-ity, initial surface absorption test and fig air, to determine thein-situ strength, durability and deterioration, air permeability, concrete quality control andperformance. Additionally, the quality of concrete was researched using test methods with experimental results. Moreover, this research has found that (1) the increase in w/c ra-tioleads to a decrease in compressive strength and ultrasonic pulse velocity. Thus, lower w/cratio gives a bet-ter concrete strength in terms of quality, (2) the quicker the ultrasonic pulse travels through concrete indicates that the concrete is denser, therefore, better quality, (3) the lower initial surface absorption value indicates a better concrete with respect to porosity and (4) the w/c ratio plays an important role in the strength and per-meability of concrete.
