4 NDT Methods for Concrete Imaging and Scanning

Concrete imaging and scanning has been an interesting topic for many materials and structural engineers, inspectors, as well as the owners. It helps identify and quantify sub-surface defects more efficiently, and comprehend the extent of damages. Different non-destructive testing methods have been developed for concrete imaging and scanning. In this article, we will review some Read more about 4 NDT Methods for Concrete Imaging and Scanning[…]

Non-Destructive Evaluation Bridge Abutments

How to Evaluate Bridge Abutments?

In a bridge structure, abutment refers to the substructure unit which supports the end of the structure (bridge span) and retains the approach fill (see Ontario Structure Inspection Manual). Abutments are commonly made of mass concrete, reinforced concrete, or wood. Usually, abutments consist of a number of components: + Foundation + Abutment wall + Ballast wall + Read more about How to Evaluate Bridge Abutments?[…]

Practical Considerations in Pile Testing

Pile Integrity Testing (PIT) is a non-destructive testing method for evaluating the unknown length and integrity of piles and deep foundations. The basic concept behind the technique is determining the velocity (required) and force (optional) response of pile induced by an impact device (normally, a handheld hammer). Pile Integrity Testing works best for long structural component such Read more about Practical Considerations in Pile Testing[…]

Limitations of Pile Integrity Testing

Applications and Limitations of Pile Integrity Test

Pile Integrity Test can be used to determine the integrity of piles. The method works best for long structural component such as driven concrete piles, cast-in place concrete piles, concrete filled steel pipe piles, timber piles, structural columns. The method works based on measuring and analyzing the velocity (required) and force (optional) response of pile. A Read more about Applications and Limitations of Pile Integrity Test[…]
