Determination of the effect of volcanic pumice replacement on macro void development for blended cement mortars by computerized tomography
Tekin, Ilker; Birgul, Recep; Aruntas, Huseyin Yilmaz (Elsevier Sci Ltd, 2012)In this study, the effect of volcanic pumice replacements with different ratios on the macro void development was observed using CT for a period of 100 days. The cured mortar specimens were imaged by X-ray CT on different ... -
Determining Hounsfield Unit values of mortar constituents by computerized tomography
Aruntas, H. Yilmaz; Tekin, Ilker; Birgul, Recep (Elsevier Sci Ltd, 2010)Computerized tomography was first developed in mid-1970 for medical purposes to non-destructively monitor the conditions of human tissues and bones The idea was to detect the transmitted X-ray radiation emitted from multiple ... -
Hilbert transformation of waveforms to determine shear wave velocity in concrete
Birgul, Recep (Pergamon-Elsevier Science Ltd, 2009)Given the density value, elastic properties of a homogeneous and isotropic material can be determined provided that primary and shear wave (P- and S-wave) velocities are known. P-waves are easier to monitor and detect ... -
Monitoring macro voids in mortar by X-ray computed tomography
Birgul, Recep (Elsevier Science Bv, 2008)In this study, X-ray computed tomography (CT) was shown to be a capable technique to quantify the evolution of macro voids and to monitor the strength development of mortar specimens. Two-dimensional image analysis was ... -
Monitoring macro voids in mortars by computerized tomography method
Tekin, Ilker; Birgul, Recep; Yaman, Ismail Ozgur; Gencel, Osman; Aruntas, Huseyin Yilmaz (Elsevier Sci Ltd, 2015)This study aims to investigate the use of ground pumice powder (PP) in cement production and to monitor void developments in mortars by X-ray Computerized Tomography (CT) which is a nondestructive test method. PP-blended ... -
Practical identification of favorable time windows for infrared thermography for concrete bridge evaluation
Watase, Azusa; Birgul, Recep; Hiasa, Shuhei; Matsumoto, Masato; Mitani, Koji; Catbas, F. Necati (Elsevier Sci Ltd, 2015)Infrared Thermography (IRT) is one of the nondestructive inspection techniques to detect delaminations in concrete bridge decks. These defects are identified by capturing the temperature gradient of concrete surfaces. In ...
