Written by adminSeptember 4, 2019 Introduction Bridges are among the most important infrastructure facilities. So far, the inspection and testing of bridge structures have largely been limited to visual inspection, chain dragging, extracting cores, and in some cases, half-cell corrosion potential mapping. Lots of interesting research have been done by researchers around
Written by adminApril 8, 2024 Introduction Nondestructive testing and evaluation (NDT&E) play a crucial role in ensuring the safety and integrity of concrete dams and hydro structures. With the growing emphasis on dam safety and the need to prolong the service life of these critical infrastructure assets, the application of advanced NDT&E
Written by adminFebruary 22, 2024 Quality control of Concrete Caissons is a challenging task. Engineers, and contractors rely on experience and well-established procedures and test standards to verify the strength, and consistency of pile materials. Non-destructive testing help reveal potential defects that might have happened during pile casting (in the case of cast-in-place
Written by adminJune 18, 2021 This article describes non-destructive testing (NDT) applications and evaluation in the inspection and condition assessment of culvert structures. Depending on their particular application, concrete culverts can be exposed to water, wastewater, and other chemicals. This can result in the deterioration of culverts during their life cycle. Non-destructive
Written by adminJanuary 17, 2023 In this article, we discuss how digital solutions such as 360 Cameras, LiDAR, and Digital Inspection platforms can help structural engineers in reducing the inspection timeline, enhance the reliability and accuracy of inspection workflow, and minimize the data processing and analysis timelines. What is Digital Inspection? Digital
Written by adminApril 29, 2023 In this article, we will discuss the non-destructive evaluation of concrete in oil and energy facilities. We will discuss how structural engineers can use data obtained from NDT/NDE to assess the structural details of a wide range of structural elements, and accurately evaluate the structural integrity, and
Written by adminJune 9, 2023 In this article, we will review 3 non-destructive testing and evaluation methods for detecting voids under concrete slabs. We will review Ground Penetrating Radar, Ultrasonic Pulse Echo, and Impact-Echo/Impulse-Response methods for evaluating the location and extent of voids under concrete slabs and pavements. Voids Under Concrete Slabs
Written by adminMay 24, 2023 Precast concrete elements are usually manufactured and cured in a controlled environment. This controlled process results in high quality and consistency of the end products. However, construction errors, formwork issues, and damages during transportation and installation can impact the quality, and integrity of these precast elements. Non-destructive
