Written by adminSeptember 11, 2017 A corroded structure (whether it is a bridge, or a jetty, or a simple ramp) could be scary for many people. Imagine yourself driving along the Gardner Express (Downtown Toronto), or the highway 40 (Montreal), and all of a sudden, a piece of concrete falls onto your
Written by adminAugust 3, 2016 Corrosion of steel reinforcement is often investigated in the context of the durability performance of the structure; however, corrosion can equally impact the structural performance. Steel corrosion may result in reduced flexural capacity (loss of rebar cross section), reduced bond, and limited ductility. In this article, we
Written by adminAugust 5, 2016 Damaged Bridges are a major concern in the maintenance and operation of transportation infrastructure. Bridge structures in North America were mainly developed in the 1960’s and 1970’s and are rapidly approaching the end of their initial service life. Major mega cities in North America spend millions of dollars
Written by adminApril 25, 2017 Half Cell corrosion mapping is an effective method for assessing the severity of corrosion activity in concrete structures. It is the most well-known procedure to identify the likelihood of active corrosion; however, the test does not provide any information about the kinetics of corrosion activity. The easy and
Written by adminNovember 7, 2017 Non-destrcutive Testing- NDT Methods for Evaluation of Parking Garages can help improve the quality of routine inspection and maintenance. Parking garages require routine inspection and maintenance to ensure they remain safe and operational. Weather it is a public parking in extremely busy downtown areas, or a private
Written by adminJanuary 17, 2019 Concrete Imaging and Scanning are used to assess the location and extent of sub-surface defects. Different non-destructive test methods have been developed and used over the past few decades. The following article briefly describes some of these methods, and their application in the structure inspection and structural
Written by adminFebruary 16, 2017 Corrosion inspection of structural anchor bolts can be quite challenging. The reason is that access to these buried elements is often very difficult. The visible part of the bolt is usually in poor quality, and mechanical tests such as pull-out is not an option. Non-destructive ultrasonic testing
Written by adminJuly 5, 2016 What happens when the patch repair is only done in damaged area? When a corrosion sign and rust stain appear on the concrete surface, it is the time to do something in order to stop corrosion propagation. Depending on corrosion type and propagation, the required intervention and
