Early-Age Cracking in Reconstructed Concrete Bridge Barrier Walls

An assessment of newly reconstructed reinforced concrete barrier walls on a highway bridge near Montreal indicated intense transverse cracking only a few days after concreting. Subsequent inspection of other concrete bridges in urban areas confirmed that such cracking is not uncommon. Analytical models, together with field and estimated data, were used to study the magnitude and roles of the fa...

Cracking Assessment in Concrete Structures by Distributed Optical Fiber

In this paper, a method to obtain crack initiation, location and width in concrete structures subjected to bending and instrumented with an OBR system (Optical Backscattered Reflectometer) is proposed. Continuous strain data with high spatial resolution and accuracy are the main advantages of the OBR system. These characteristics make this Structural Health Monitoring (SHM) technique a useful t...

Different Damaged Shaft Lining Concrete Resistance to Sulfate Corrosion

Shaft lining concrete itself has a certain degree of initial damage before being corroded by sulfate. In order to study the resistance of the concrete of the initial damage in different corrosion solution concentration of sulfate, samples of concrete without initial damage, loaded 50% ultimate load and loaded 70% ultimate load with initial damage concrete were selected and studied their corrosi...
