Quality assurance of concrete foundation elements using an ultrasonic evaluation technique
This paper presents the approach and results adopted in a proactive quality assurance testing technique which was used to inspect, in a non-destructive manner, the integrity and homogeneity of over 200 different in-situ cast concrete foundation elements (ie bored piles, concrete barrette piles and diaphragm wall panels) in various Hong Kong construction sites. The test results were obtained from both public and private buildings and civil engineering projects in Hong Kong. The Cross-hole Sonic Logging (CSL) testing technique covered and reported in this paper has been proven a reliable and useful technique for assessing the quality of concrete and the integrity of foundation elements. The proof of its applicability has been achieved by the results obtained from the extensive tests carried out (within the HKSAR territories) and also examples shown in this paper. Questionable/suspected defects found have been reported and discussed thoroughly and classified into several categories. The authors experience shows that CSL provides precious information/feedback regarding the construction process of the final finished products (ie concrete foundation elements in this case). This would not be possible otherwise without the help of ultrasonic evaluation techniques in general and CSL in particular.
