I'd been on my 7-2 but needed to paddle out with the 9-6 today because I had to take another look at the delamination at the back foot that Joe Roper had noticed in his shop. Actually I think one of his employees noticed it first, but then Joe gave the board a full rundown and decided it might need to get a whole new deck. A couple of years ago I did some repairs on the extensive delam it came with off the rack at Coconut Peet's, so it's better than it used to be, but they noticed that I didn't get all of it, which I knew at the time, but ignored because I just wanted to paddle out with the thing. I like the board a lot -- it turns better than my 9-2 even though the 9-2 is shorter and has way less mass. There's smething about the way this old Rusty log was shaped that just makes it work the magic a little better. Now I'm going to wait for a hot sunny day on the beach so I can scrape off all the wax and start working on getting the deck glass reattached to the foam again. #boardrepairs #delamination #longboarding #ninesix #log #rusty #surflife #california https://www.instagram.com/p/Byq2WVEAm2K/?igshid=6wt4cord6kcs

Bridge Repair

Concrete is very strong in compression but very weak in tension. To build large structures like bridges it is combined with steel so that in regions where there is tension the steel will bear the load and in regions where there is compression the concrete will bear the load. Because concrete contains a large amount of calcium hydroxide it is very basic which protects the steel from corrosion as long as it is fully covered by concrete. Over time carbon dioxide will diffuse through cracks in the concrete making it more acidic and allowing the steel to corrode. When steel corrodes it expands forming a layer of rust that separates the steel from the concrete in a process called delamination. When this happens the structure must be repaired because now the steel is no longer effectively connected to the rest of the structure.

To detect this bridge engineers will regularly perform a chain-drag test. Here several chains are attached to a bar which a technician will carry while walking across the bridge. As the chains rattle across the concrete they generate sound waves that travel through the bridge. If delamination has occurred the sound waves will bounce off the layer of corrosion and make a distinct hollow sound. The operator can then mark that part of the bridge as needing repair.

For a long time the only way to detect delamination was a trained ear, but some new non-destructive testing techniques are now being rolled out (Imaging Concrete Structures Using Air-Coupled Impact-Echo by Jinying Zhu and John S. Popovics 2007)

This @polyalchemy is seriously annoying the @#$! Out of me. Running it at 220c... Guess I'll try 240c this time but seems ridiculous for PLA... #delamination #3Dprinting (at Gresham, Oregon)
