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

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

How To Estimate Strength of Concrete Using NDT Methods?

  • by

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?

Protecting Concrete in Cold Weather

  • by

Protecting concrete in cold weather is a continuous challenge for concrete contractors and site supervisors. Placing concrete in the cold weather condition requires special preparation and protection. All necessary precautions should be taken in order to to alleviate the negative impacts of cold weather. Special curing and protection is required in most cases.  In my previous article, we reviewed what is considered cold for concrete construction, and what should be… Read More »Protecting Concrete in Cold Weather

How to Evaluate Compressive Strength of Concrete

  • by

What is the best method for the measurement of compressive strength of concrete? Testing cylinders and cubes in compression is the most convenient and well-known method for measuring the strength. The main question is if one can design and develop a method that can measure the strength faster, easier, and more accurate? Can all the advancements in sensor technology and better understanding of the development of concrete microstructure can help… Read More »How to Evaluate Compressive Strength of Concrete
