Non-Destructive Evaluation of Concrete Structures

How to Test Concrete Using Impact-Echo ?

  • by

In this article, we will briefly present and discuss Impact-Echo (IE) method for testing concrete structures. The method has proven to be extremely useful in evaluating the thickness of concrete elements from one side (e.g. tunnel lining, culvert wall, bridge abutment), determining the depth and location of subsurface defects (e.g. cracks, voids, honeycombing, debonding) within concrete, and estimating the depth of surface-opening cracks. The test method was first adapted in… Read More »How to Test Concrete Using Impact-Echo ?

Ultrasonic Pulse Echo

Ultrasonic Pulse Echo Tomography for Concrete

  • by

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 side access (i.e. tunnel linings, trunk sewer linings, abutment walls), detect sub-surface defects such as voids, honeycombing, and delamination, and to verify Location… Read More »Ultrasonic Pulse Echo Tomography for Concrete

Inspection and Evaluation of Concrete Beam

Non-Destructive Evaluation of Cracking in Concrete Beams

  • by

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 width and crack depth are measured using NDT methods. GPR scan is used to determine structural detailing of beam, such as the location… Read More »Non-Destructive Evaluation of Cracking in Concrete Beams

On Site Evaluation of Concrete Strength - FPrimeC Solutions

5 Methods for On-Site Evaluation of Concrete Strength

  • by

On-site Evaluation of Concrete Strength is a main challenge in the condition assessment of existing infrastructure, or the quality control of new construction. Owners, maintenance managers of such existing concrete structures normally prefer non-destructive and non-intrusive methods to avoid further damage to an already struggling structure. In construction projects, switching to non-destructive means less intervention, shorter down-times, and saving money. However, all parties agree that the strength of concrete is… Read More »5 Methods for On-Site Evaluation of Concrete Strength

Cold Joints in Concrete Beams

Non-Destructive Evaluation of Cold Joints in Concrete

  • by

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? Cold joints in concrete primarily happen when there is a significant delay between different concrete pours. For examples, if there is an interruption… Read More »Non-Destructive Evaluation of Cold Joints in Concrete

Non-Destructive Testing of Wind Turbine Foundation

Non-Destructive Testing of Wind Turbine Foundation

  • by

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 of their foundation is relatively limited. In this article, we will review how Non-Destructive Testing of Wind Turbine Foundation can help engineers in… Read More »Non-Destructive Testing of Wind Turbine Foundation

Non-Destructive Testing for Detailed Bridge Condition Survey

Non-Destructive Testing for Detailed Bridge Condition Survey

  • by

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 the globe to bring more innovative NDT solutions to this sector. The following article focuses on the applications of most widely used non-destructive testing for… Read More »Non-Destructive Testing for Detailed Bridge Condition Survey

Low Strain Pile Integrity Test

How To Perform Low Strain Pile Integrity Test?

  • by

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
