On-Site Evaluation of Concrete Strength

5 Methods for On-Site Evaluation of Concrete Strength

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, Read more about 5 Methods for On-Site Evaluation of Concrete Strength[…]

Non-destructive testing of concrete foundations

Non-destructive Testing of Concrete Foundations

Concrete foundations are a key component in every major structure. They provide the much-needed stability to structural systems, and/or heavy industrial equipment they are supporting. The foundation system and type depend heavily on the superstructure load, and soil properties. As a result, concrete foundations may appear in different shapes, and sizes. In general, foundations can Read more about Non-destructive Testing of Concrete Foundations[…]

Cold Joints in Concrete Beams

Non-Destructive Evaluation of Cold Joints in Concrete

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 Read more about Non-Destructive Evaluation of Cold Joints in Concrete[…]

Non-Destructive Testing of Wind Turbine Foundation

Non-Destructive Testing of Wind Turbine Foundation

Over the past decade, Canada has heavily invested in wind energy, increasing its annual capacity from nearly 2,000 MW in 2008, to 13,000 MW in 2019. That is enough to power approximately 3.3 million homes – 6% of our country’s electricity demand (Canadian Wind Energy Association, 2019). There are 299 wind farms operating from coast Read more about Non-Destructive Testing of Wind Turbine Foundation[…]

Non-Destructive Testing for Detailed Bridge Condition Survey

Non-Destructive Testing for Detailed Bridge Condition Survey

The following article is a quick review of the most cost-effective and easy to implement non-destructive testing for detailed bridge condition survey. We were recently involved in a detailed bridge deck condition survey in Perth, Ontario. The main objective was to inspect and evaluate the existing condition of the bridge deck, identify surface and subsurface Read more about Non-Destructive Testing for Detailed Bridge Condition Survey[…]

Non-Destructive Testing for Structural Condition Assessment

Non-Destructive Testing for Structural Condition Assessment

Structural Condition Assessment usually refers to the process of collecting observations and data about the existing condition of the structure through systematic and scientific methods. According to the Professional Engineers Ontario Guideline for “Structural Condition Assessment of Existing Buildings and Designated Structures” (PEO, Nov 2016), structural condition assessment are within the practice of professional engineering. Read more about Non-Destructive Testing for Structural Condition Assessment[…]

In-Place Methods to Estimate Concrete Strength Using Rebound Hammer

Estimate Concrete Strength Using Rebound Hammer

In-Place Test methods to estimate concrete strength has been extremely popular among engineers and inspectors involved in the field of structure inspection, evaluation and condition assessment. Various non-destructive methods have been developed by different researchers over the past few decades to assess in-place strength of concrete. The rebound hammer, developed by Ernst Schmidt, provides an Read more about Estimate Concrete Strength Using Rebound Hammer[…]

the future of bridge inspection

The Future of Bridge Inspection

The Canadian Highway Bridge Design Code (S6-14, 2014) considers a service life of 75 years for newly constructed bridge. What does this mean in engineering terms? It means that the bridges of the future should have satisfactory performance, both durability and structural, during the proposed life-cycle. This can be quite challenging when we look closely; Read more about The Future of Bridge Inspection[…]

How To Test Concrete Using Impact-Echo Method

How to Test Concrete Using Impact-Echo Method?

In this article, we will briefly present and discuss Impact-Echo (IE) method for testing concrete structures. The concept behind the technique will be reviewed. We will also study the applications and limitation of the IE method and How to Test Concrete Using Impact-Echo Method.  The test method was adapted as a standard test procedure by the Read more about How to Test Concrete Using Impact-Echo Method?[…]
