Written by adminMarch 14, 2021 This article describes the applications of non-destructive testing (NDT) and evaluation in the inspection and condition assessment of Concrete tanks. Depending on their particular application, concrete tanks are exposed to water, wastewater (sewer), and other aggressive chemicals. This can result in deterioration of concrete during its life
Written by adminNovember 15, 2020 Extreme cold weather conditions can significantly affect the quality of concrete, as well as its mechanical properties. In cold weather concreting, one should make sure that all the negative impacts of low ambient temperature are appropriately alleviated by taking the necessary precautions. In this article, we will
Written by adminJanuary 31, 2021 In this article, the basic principles and the advantages of Ground Penetrating Radar (GPR) in concrete scanning and its comparison to other concrete scanning NDT techniques will be presented. This technique is greatly beneficial to contractors and engineers working in the construction industry. What is Ground Penetrating
Written by adminOctober 7, 2020 A multi-technology approach using different Nondestructive Testing (NDT) technologies is becoming the new standard in structural condition assessment. Ground Penetrating Radar has proved to be an effective method in collective key information about the structural details, however, this interesting technology comes with inherent limitations. It is important
Written by adminSeptember 25, 2020 Nondestructive Testing have great applications in the concrete construction industry. It helps designer, construction engineers, and contractors the ability to verify the quality and integrity of built structures, identify and quantify potential defects, and record as-built condition like never before. The author has several years of combined research
Written by adminJune 24, 2020 In this article, we will review an interesting category of ultrasonic test methods for concrete inspection and testing: Ultrasonic Pulse-Echo (UPE) is widely used for the inspection of concrete elements. The method has proven to be extremely useful in determining the thickness of concrete elements with one
Written by adminMay 29, 2020 In this article, and presentation, we are going to describe using non-destructive evaluation of cracking in concrete beams. The main reasons behind cracking is discussed. A systematic approach for evaluating the current condition of the beam is presented. Certain features of concrete cracks, such as the crack
Written by adminNovember 4, 2019 This technical note briefly discusses non-destructive evaluation of cold joints in concrete structures. We will review how structural engineers and quality control laboratories can utilize NDT methods to assess the quality and integrity of concrete on or around the cold joint. What is Cold Joint in Concrete?
Written by adminSeptember 20, 2019 Harvesting wind energy has been of special interest over the past decade. There are approximately 300 wind farms across Canada.Wind turbine structures are very complex. While the inspection of the turbine and tower has been very well developed, the literature on evaluating the quality, integrity and reliability
Written by adminMay 30, 2019 Pile Integrity Test (PIT) is normally performed by striking the pile head with a light hand-held hammer and recording the response of the pile using a motion transducer (i.e. accelerometer) coupled
