Onoff Posted April 1, 2018 Author Share Posted April 1, 2018 14.35hrs Easter Sunday...firing up the mixer! 1 Link to comment Share on other sites More sharing options...
Onoff Posted April 1, 2018 Author Share Posted April 1, 2018 (edited) Interesting mix that was! Smells like when you work with plastic. Pretty sticky! 5l bucket cement 7.5l bucket 10mm pea shingle 7.5l bucket sharp sand So 1 : 1.5 : 1.5 3:1 water to SBR A handful of fibres Repeat! Seemed to go in alright though: You can see the fall line: And from a distance how it falls overall. Not sure if it'll float when bit drier or even if it's necessary. Hoping the angle and flat steel plates will come off alright and not be stuck. Whatever, TF for thick tile adhesive!

Onoff Posted April 2, 2018 Author Share Posted April 2, 2018 I have no idea how long this mix will take to dry out before tiling. With the SBR in it's unchartered territory. The old 'X' mm per day is out the window I imagine? Does the fact it's waterproof concrete mean water is excluded from the start, how does this stuff dry out? Will it dry quicker? Couldn't resist trying a bit more tamping on the rhs section last night. Funny how that bit is now "drying" quicker. Tbh it was bringing fibres to the surface so had to force myself to leave it. Not sure if I should have covered it with a plastic sheet...too late now? I might go over it with a heavy metal plate just to knock the odd snot off of it here and there The wife commented how much bigger it looked last night...

newhome Posted April 2, 2018 Share Posted April 2, 2018 Yay, real progress (as opposed to fannying ). And if it’s looking bigger - good for you 1 Link to comment Share on other sites More sharing options...

I'm sure someone will correct me on this, but I was told that concrete doesn't dry out, it cures, so the water somehow reacts and stays in it as part of the compound,........ JFM so it shouldn't take that much longer than normal, but it might be worth getting a moisture meter if you are the kind of person that worried too much might be worth just running over the top with something while it is still green just to take the snots off, I would have suggested a plastic float but anything flat should work. 1 Link to comment Share on other sites More sharing options...

Yeah I've read similar. Got a good piece somewhere about how for many years concrete has a protective effect on steel reinforcing within due to its alkalinity. Over time though CO2 seeps in and acidifies everything causing the steel to rot. The article was on why the early art deco concrete buildings failed and what was being done to save them. There's some process now that arrests the rot. Guess modern admixtures have an effect too on concrete today? Link to comment Share on other sites More sharing options...

Was debating uscrewing the former angles by the drain now along with taking out the screws holding the flat plates down? Not sure how well I rammed in the new stuff against old but I did prime the old first with neat SBR. Link to comment Share on other sites More sharing options...

Yes, it needs a fair bit of water in order to hydrate and cause the chemical reactions that make it cure. It doesn't really "dry out" as such, apart from any excess water that's been added to make it flow better, and generally that excess will come to the top pretty quickly, leaving enough water behind to allow the reactions to complete. The chemistry is damned complex, and even now not well understood, but keeping concrete/mortar damp during the initial curing phase is pretty much essential. After a day or so it doesn't matter normally, as most of the water will be locked up inside and will continue to help the cure. The stuff is really weird, as it can go on curing internally for decades, reaching peak strength after maybe 20 or 30 years or so. 1 Link to comment Share on other sites More sharing options...
Onoff Posted April 2, 2018 Author Share Posted April 2, 2018 Took the first steel off...might be a tad high on the right... Link to comment Share on other sites More sharing options...
PeterW Posted April 2, 2018 Share Posted April 2, 2018 Get the steel and use as a scraper to take the green edge off and it will be fine. Link to comment Share on other sites More sharing options...
Onoff Posted April 2, 2018 Author Share Posted April 2, 2018 This Sika product is like what I was talking about for protecting steel within existing concrete. https://gbr.sika.com/en/solutions_products/sika-markets/concrete-repair/total-corrosion-management/multi-functional-corrosion-inhibitors.html There was a really good piece in one of the broadsheets a few years back to do with carbonated old concrete and it's re alkalisation. Guessing Sika bought them out maybe? Link to comment Share on other sites More sharing options...
Onoff Posted April 2, 2018 Author Share Posted April 2, 2018 Trim removed and scabbled with a metal plate: Not sure whether I should smooth that edge where the angle former came off? @Nickfromwales, from 3m50s onwards in this video: what's the "stuff" they're trowelling on to stick the drain membrane down?

ProDave Posted April 2, 2018 Share Posted April 2, 2018 Shall we have a sweepstake on who is going to be the first to shower in their new bathroom, @Onoff or me? hint: The only thing stopping ours being used now is lack of hot water tank. Link to comment Share on other sites More sharing options...

The only thing stopping ours being used now is lack of insulation, plumbing, electrics, Aquapanel, tanking, plaster, tiles... I do have a hot water tank though... 1 Link to comment Share on other sites More sharing options...

Onoff Posted April 2, 2018 Author Share Posted April 2, 2018 (edited) Quite noticeable how much denser the newly laid wet room corner is / feels to walk on compared to the rest of the floor that has Polypipe panels underneath. So now I need to mitre the corner. Planning on just going across the noggins in the walls though I need to put some more in: Edited April 2, 2018 by Onoff Noggings or noggins?

Onoff Posted April 2, 2018 Author Share Posted April 2, 2018 (edited) When I turn the bath tap (s) off it sounds like the pipes are banging in the wall! Not always though. I thought I'd been really careful clipping and insulating. So up in the loft: Then down through the ceiling: Then down the wall in 'Vs': The 'Vs' removed have been fiamed back in less the pipe stand off. This is all packed with insulation now: Maybe where the pipes pass thru here? I could foam in there? Just can't figure it.

Nickfromwales Posted April 2, 2018 Share Posted April 2, 2018 It's not banging in the new stuff, it just sounds like it is. It'll be water hammer due to the new taps being 1/4 turn instead of 10 turn. Link to comment Share on other sites More sharing options...

Pressure at the moment is pretty good tbh. Link to comment Share on other sites More sharing options...
