snoop1130 Posted July 10, 2019 Share Posted July 10, 2019 Concrete pieces from Ari BTS station in Bangkok fall on road below By The Thaiger PHOTO: Isara Ariyachaipanich Concrete panelling has fallen from the Ari skytrain station. Luckily there was no one injured. Isara Ariyachaipanich posted photos on his Facebook page showing a huge slab of concrete laying on the road beneath the structure of the Ari BTS station. The concrete fell onto Phayon Yothin Road, near a local bus station. “It was so good it didn’t hit anyone. Bus driver moved it to the side of the road. If it had hit a car or a motorcycle, there would be a dead person.” Isara said he has messaged BTS officials through their Facebook page, but the operators have not responded or issued a statement about the incident. Isara posted the photos at about 7am Wednesday. The post has been shared more than 3,600 times and accumulated 2,100 comments.

Popular Post SteveK Posted July 10, 2019 Popular Post Share Posted July 10, 2019 Thais aren't great at maintenance from my experience - because it costs money with no appreciable benefit. Better to wait until it breaks and then fix it. 6 3 1 Link to comment Share on other sites More sharing options...

Popular Post overherebc Posted July 10, 2019 Popular Post Share Posted July 10, 2019 Concrete is a bit of a science, not just mix the parts and use it. Some problems arise if beach sand is used ( salty ). Initially it helps to speed setting time a bit and strangely increase compressive strength but has an adverse effect on re-bar in the concrete. As the re-bar corrodes it expands and starts to crack the concrete around it sometimes causing bits of the concrete to fall off. Not saying that's what happened here though. Could be many other reasons. 8 Link to comment Share on other sites More sharing options...

Lupatria Posted July 11, 2019 Share Posted July 11, 2019 What happened to the traditional explanation blaming someone or something else? Here's a hint: It's caused by rain, sun, wind, humidity, or moonshine. In short, why not blame mother nature in general? 1 Link to comment Share on other sites More sharing options...

It was ok yesterday so it will be all right tomorrow. Must admit too much moonshine during the construction can have an effect.

userabcd Posted July 11, 2019 Share Posted July 11, 2019 (edited) Not the first time one of those panels have fallen down. Always wondered about the design how they have secured those thin concrete panels with bolts on each corner of the thin panel to the metallic frame and with the degradation of the concrete over time. These side panels are mostly over traffic lanes and pedestrians and it's only a matter of time until someone is seriously hurt.

hotchilli Posted July 11, 2019 Share Posted July 11, 2019 Just the usual build it and forget it mentality.. Thailand has a love affair with concrete which unfortunately has a shelf life. That's fine for homes, knock-em down & rebuild... Larger infrastructure is another issue, especially if it's overhead, such as roads, bridges or railways!

Could be many other reasons Yep especially if the concreted mix has inadequate additives which are added to stop reo corrosion as part of the suite of additives added for r other reasons e.g. curing speed. The thickness of that flake looks way too thin to me and points to what your offering up. If the reo is too close to the surface of the concrete it will corrode yes, expand and flake off. If concrete is poured in a sequence and too slowly into the formwork layering can occur this too can lead to flaking, using another batch of concrete one on top of the other and it’s not consistent in mixes this too will cause layering and weakness and can flake. in super hot conditions if the formwork gets really hot the first part of a pour into it will dry too rapidly this affects strength too. bloody dangerous ! 1 Link to comment Share on other sites More sharing options...

I've only just enlarged the photo and I'm not sure what the chunk is. Could be one of the side panels similar to ones they use on overpass road sections etc or a kind of 'finishing panel that was stuck on the outside of a pillar ( unlikely I admit ). Really need a photo of where it came from to be sure. Re' salt I believe 'fly ash' in the correct % helps to fix the salt problem.

Don't tell me there isn't any monitoring of the production of the concrete for these panels.? I ( seriously ) used to get up at 5am to go to a plant where the sand, cement and aggregate quantities were measured, noted and signed off, by me, prior to mixing. Any additives as well. Post mix samples were formed in bolt together formers and sent to the lab for testing. Hold on, just remembered it was in UK. ????????

overherebc Posted July 12, 2019 Share Posted July 12, 2019 I wonder how many people are aware that on flyovers/overpasses those kind of 'stick them on the edge' panels are not designed as crash barriers but are merely noise reduction panels.

ExpatOilWorker Posted August 15, 2019 Share Posted August 15, 2019 If all the concrete panels are attached with raw carbon steel bars like the below, surely more will come crashing down in the years to come. 1 Link to comment Share on other sites More sharing options...
