http://microlab-m3c4.blogspot.com/2013/05/big-city-big-conference.html
Join our Group in LinkedIn. Monday, May 13, 2013. Big city, big Conference. The view of Chicago's skyline from Jon Hancocks's Observatory. The 35th International Conference on Cement Microscopy was held from April 29th to May 1st in Chicago, Ill. The M3C4 had the opportunity to attend and show some of the research lines we've been currently looking into. The conferece had a lot of interesting presentations and extensive discussions regarding cement microscopy. Headquarters of PCA, Skokie, Ill. Bending cr...

M3C4: Corrosion of steel in concrete
http://microlab-m3c4.blogspot.com/2013/08/corrosion-of-steel-in-concrete.html
Join our Group in LinkedIn. Wednesday, August 7, 2013. Corrosion of steel in concrete. Figuring out what is really going on during corrosion of steel in concrete is no easy task That's why we use advanced experimental techniques to characterize the process. Here's an example:. Stay tuned for updates! How corrosion induced cracking takes place:. Also, different cross sections of the same beam can be observed (top - with PVA fibers; bottom - no fibers):.

M3C4: Wedge splitting test
http://microlab-m3c4.blogspot.com/2011/11/wedge-splitting-test.html
Join our Group in LinkedIn. Thursday, November 10, 2011. Wedge splitting test is a simple test often used in fracture mechanics. Some trial tests were perfomed in the Microlab last week.

M3C4: Bending cracks in reinforced concrete cubes
http://microlab-m3c4.blogspot.com/2013/06/bending-cracks-in-reinforced-concrete.html
Join our Group in LinkedIn. Wednesday, June 19, 2013. Bending cracks in reinforced concrete cubes. During the course of the M3C4 research, a Modified Wedge Splitting Test (MWST) was employed as the main source of getting controlled cracks in reinforced concrete specimens. For this purpose, we used concrete cubes that contained a recess, where the action of the wedges is applied; and two reinforcing bars embedded in concrete. More results are about to come.

M3C4: Corrosion pits in steel bars embedded in cracked concrete
http://microlab-m3c4.blogspot.com/2013/08/corrosion-pits-in-steel-bars-embedded.html
Join our Group in LinkedIn. Tuesday, August 20, 2013. Corrosion pits in steel bars embedded in cracked concrete. Here is a short update on what I've found on inspecting the bars after extracting them from the specimens. The first image shows the size of pits found in a specimen with a 'smaller' crack width'. The second image shows what happens when the crack width in increased. Both specimens were subject to the same amount of salt-dry cycles. Until next time,. Subscribe to: Post Comments (Atom).

M3C4: Glowing concrete
http://microlab-m3c4.blogspot.com/2012/01/glowing-concrete.html
Join our Group in LinkedIn. Friday, January 13, 2012. It seems that concrete properties also include glowing under UV light! Cracks allow aggressive substances to reach into concrete. In this case, the crack pattern is visible when it has been filled with epoxy. We would like to take this opportunity to wish you success in all your endeavors. Until next time! Photo by: J. Pacheco.

M3C4: Visual analysis of corroded bars
http://microlab-m3c4.blogspot.com/2013/08/topographic-images-of-corroded-bars.html
Join our Group in LinkedIn. Friday, August 2, 2013. Visual analysis of corroded bars. I've been working on the analysis of corroded reinforcing steel embedded in cracked concrete. The cubes were mechanically split so the reinforcement can be assessed. All images are taken with the stereomicroscope. Layer of orange rust can be observed on the steel surface. However, there are still some corrosion free spots. The original image size was aprox. 17000 x 1300 microns*. Until next time,. TU Delft – CiTG. Study...

M3C4: Corrosion induced cracking
http://microlab-m3c4.blogspot.com/2013/05/corrosion-induced-cracking.html
Join our Group in LinkedIn. Wednesday, May 22, 2013. When steel corrodes, a rust layer is created around it which exerts pressure on the concrete cover. Although much is known about this process, it would be nice to be able to study it non-destructively. How? Well, we might have a trick up our sleeve! Keep checking the blog for news!
