We will review the concept behind the maturity technique, and the most common practices. Later, we will describe the benefits and limitations of this method for in-place strength prediction. In the last part
Written by adminOctober 12, 2016 Non-destructive evaluation of unknown foundations and piles has gained interest among engineers and researcher over the past few years. Latest research show the effectiveness of these methods in investigating the depth and quality of existing piles, as well as in the quality assurance of new construction. Piles
Written by adminSeptember 26, 2016 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
Written by adminSeptember 20, 2016 I would like to start this by a very simple example: that infrastructure facilities work very similar our body. When they are first built (i.e. like when we are at our young age), they operate at their best. Just a routine checkup is all you need to
Written by adminSeptember 6, 2016 NDT methods can be used in routine inspection projects; they can be used to follow up the state of damages in periodical checks. The other advantage of NDT methods is that they can be performed by minimum intervention to the structure. This helps prevent aggravating the problems

Written by adminAugust 10, 2016 Deterioration of reinforced concrete structures can happen for a number of reasons. Physical and Chemical processes can impact durability and structural performance of the concrete. Defects in design, materials, workmanship, curing and maintenance can all impact the service life, safety and reliability of an element. In this
Written by adminAugust 5, 2016 Damaged Bridges are a major concern in the maintenance and operation of transportation infrastructure. Bridge structures in North America were mainly developed in the 1960’s and 1970’s and are rapidly approaching the end of their initial service life. Major mega cities in North America spend millions of dollars
Written by adminAugust 3, 2016 Corrosion of steel reinforcement is often investigated in the context of the durability performance of the structure; however, corrosion can equally impact the structural performance. Steel corrosion may result in reduced flexural capacity (loss of rebar cross section), reduced bond, and limited ductility. In this article, we
Written by adminJuly 5, 2016 What happens when the patch repair is only done in damaged area? When a corrosion sign and rust stain appear on the concrete surface, it is the time to do something in order to stop corrosion propagation. Depending on corrosion type and propagation, the required intervention and
