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. This primarily fall in two categories: Preliminary assessment Detailed condition assessment Depending on the objectives… Read More »Non-Destructive Testing for Structural Condition Assessment
In this article, we will briefly review how to Estimate Strength of Concrete Using NDT Methods. Compressive strength of concrete is by far the most important property of concrete. It represents the mechanical properties of concrete; for example, the 28 days compressive strength of concrete cylinders is the key parameter in most design codes (ACI 318-14, CSA A23.3-14). Concrete strength is found to have reasonable relationship with certain durability parameters of concrete.… Read More »How To Estimate Strength of Concrete Using NDT Methods?
Why concrete structures fail? Concrete has long been known as a reliable construction material, but deficiencies in material selection, detailing, and design can affect the service life of Concrete. Deterioration of concrete structures can become a challenge for the owners of these structures. It is important to identify these defects on time, and plan appropriate repair strategies. In this article, we will review some of the most famous deterioration mechanisms. In… Read More »Deterioration of Concrete Structures
