Protecting Concrete in Cold Weather

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 Read more about Protecting Concrete in Cold Weather[…]

On-Site Evaluation of Concrete Strength

5 Methods for On-Site Evaluation of Concrete Strength

In this article, we will review the potential options and practical solutions for on-site evaluation of concrete strength. Concrete (compressive) strength 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 Read more about 5 Methods for On-Site Evaluation of Concrete Strength[…]

How to Evaluate Compressive Strength of Concrete

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 Read more about How to Evaluate Compressive Strength of Concrete[…]

Model Structural Concrete

How to Model Structural Concrete?

Modeling concrete for structural properties can be quite challenging. Concrete is not a homogenous material; the placement and fabrication of concrete increases the degree of uncertainties, which makes it a complicated material . The question is how to model structural concrete? In this article, we will review some of the most well-known models. Model Structural Concrete Read more about How to Model Structural Concrete?[…]

Structural Effects of Corrosion

Structural Effects of Corrosion

You may think that corrosion in structures is a just a durability-related issue in the first glance. Well, that is far from the truth. In fact, corrosion can directly affect mechanical and structural properties of components. Corrosion can affect the global response of the structure. In this article, we will review some of the main Read more about Structural Effects of Corrosion[…]
