RMweb Premium PhilJ W Posted August 9, 2015 RMweb Premium Share Posted August 9, 2015 The modern idea is to let it rust in the open air so that any expansion happens before the concrete is poured. I'm not sure though of the effect of salt water on the process. Link to comment Share on other sites More sharing options...
Keith George Posted August 9, 2015 Share Posted August 9, 2015 Are there going to be handrails all along the sea-wall walkway.? If so it would be a lot safer with children/grandchildren in tow. Keith. Link to comment Share on other sites More sharing options...

RMweb Gold SHMD Posted August 9, 2015 RMweb Gold Share Posted August 9, 2015 Iron oxide takes up more volume than the original Fe + O2. When iron 'rusts' it takes up more 'volume' than the original metal. Now Whilst concrete is very strong – it is very strong in compression but quite weak in tension. The 'Concrete Cancer', of the 60s and 70s, was mainly due to the reinforcing bars being too close to the surface and thus oxygen could infiltrate down to the re-bar where it reacted with the iron forming Iron Oxide, or Rust, and then expanded allowing more oxygen in to even greater depths until the structure became too degraded and structural failure became a risk. ReBar, 'buried' deep enough, quickly uses up all the available oxygen and the process goes no further. Whilst Dawlish does get a 'hammering' the concrete works are not critical load bearing structures. Both of these facts, along with the idea that the rust already there provides enough 'space' for the remaining rust material to 'expand' into, meaning that no 'cleaning of the reBar is necessary. (Now Bridges where weight, space and quantity of materials require that there reBar is much nearer the surface means that the 'Rust' is sometimes needed to be removed by sandblasting before the concrete is poured.

Keith. No, only around the tops of the new steps, really hand rails to assist those using the steps. There will be no handrails for the majority of the length of the wall, which is as it has been for most of its history. 5 Link to comment Share on other sites More sharing options...

Granitechops Posted August 10, 2015 Share Posted August 10, 2015 (edited) Just wondering when Slaters Plasticard embossed stone sheets will be stuck onto the new concrete wall sections? Nah, you all got it wrong The plasticard is going on the top of the walkway, horizontal layer not the front vertical face Edit and I did hear that after the main tourist season is over that in the autumn the walk way will be closed again to accomplish that Edited August 10, 2015 by Granitechops Link to comment Share on other sites More sharing options...

stewartingram Posted August 14, 2015 Share Posted August 14, 2015 Maybe a tad early for this, but that time is drawing near. A BIG thanks to Granitechops for all these informative - and interesting - reports from Dawlish. Without being disrespectful, I'm sure it was not the easiest of tasks for a disabled person to do, I have full admiration for your perseverance, and I'm sure you've enjoyed being involved. Thank You, Sir, much appreciated. I'm sure many others here will agree. Stewart 4 Link to comment Share on other sites More sharing options...
Corsaire Posted August 14, 2015 Share Posted August 14, 2015 On this auspicious day and after following this thread from afar since the start. Can I congradule all the correspondents especially " Granitechops" for his granite like determination to get the "story" also Captain Kernow for his insider information. They have all enabled those of us who do not have access to the area to be well informed of all the events concerning this wonderful reconstuction. This thread stands as a tribute to you all Link to comment Share on other sites More sharing options...

RMweb Gold Captain Kernow Posted August 14, 2015 RMweb Gold Share Posted August 14, 2015 Well, I went to the opening ceremony at lunch time today, in an official capacity, and took a few photos, including one or two of Don, who was also there, of course, and had the distinction of being the first buggy driver to pass over the new section of Sea Wall. The new section of wall was opened by Network Rail Western Route Director Patrick Hallgate, with the Mayor of Dawlish cutting the ribbon. Press & media were also there, as was a mobile ice cream kiosk at the Rockstone end, kindly provided for the guests by Network Rail: 17 Link to comment Share on other sites More sharing options...

RMweb Premium brushman47544 Posted August 14, 2015 RMweb Premium Share Posted August 14, 2015 Let's hope it's not too serious, but at least it will be a timely reminder to politicians of the promises they made into looking at diversionary route(s) that might otherwise have been quietly parked in the long grass.
