Abstract

Cylindrical concrete cores of 10 cm diameter and height were taken from the columns and shear walls of randomly chosen 5-40 years old reinforced concrete (RC) buildings located in different towns of Istanbul and Izmit (Kocaeli) in Turkey from 2000 to date. The ultrasonic pulse velocity (UPV) measurements and uniaxial compressive strength (UCS) tests were conducted on 200 concrete core specimens in our laboratory. The core UCS of the specimens regressed against UPV and linear regression equations were obtained.

 

Key words: Concrete, ultrasonic pulse velocity (UPV), Istanbul, Izmit, Turkey.

Abbreviation
