Precautions for Cold Weather Concreting

  • by

Extreme cold weather conditions can significantly affect the quality of concrete, as well as its mechanical properties. In cold weather concreting, one should make sure that all the negative impacts of low ambient temperature are appropriately alleviated by taking the necessary precautions. In this article, we will review important steps that can ensure you will get the quality you are looking for. But first, let’s see what cold temperature is… Read More »Precautions for Cold Weather Concreting

Applications of Nondestructive Testing for Concrete Construction

Applications of Nondestructive Testing in Concrete Construction

  • by

Nondestructive Testing have great applications in the concrete construction industry. It helps designer, construction engineers, and contractors the ability to verify the quality and integrity of built structures, identify and quantify potential defects, and record as-built condition like never before. The author has several years of combined research and industrial experience in helping construction industry in Canada, and has witnessed how NDT can help identify and quantify location and extent of potential… Read More »Applications of Nondestructive Testing in Concrete Construction

Monitoring of Ground-Borne Vibrations from Construction and Demolition

  • by

Ground-Borne Vibration can be a serious concern for any building or structure within or adjacent to a construction zone. These structures may be potentially impacted by vibrations emanating from construction activities such as demolition, compaction, excavation, blasting, pile-driving, and operating heavy earth-moving equipment. In extreme cases, the vibration can cause damage to adjacent buildings and create discomfort and annoyance for building occupants. This is a particular concern to heritage structures… Read More »Monitoring of Ground-Borne Vibrations from Construction and Demolition

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

Reuse of existing piles and deep foundations

Reuse of Existing Piles – How NDT Can Help

  • by

Safety, reliability and satisfactory performance of structures require a well-planned maintenance program, as well as remedial actions in short and mid-term. Existing structures that are designed in accordance with older design codes or were built by older construction practices may need to be extensively repaired, rehabilitated, or replaced within the next few years. The remedial actions may include structural and/or foundation upgrade or replacement. Reuse of existing piles and foundations is… Read More »Reuse of Existing Piles – How NDT Can Help
