metis - no, that's the only reference I have, but it just seemed a bit odd that if they had the technology to print the whole thing at once, they would then print it in sections.

To be honest I'd taken it for granted that it was a single piece until you provided the patent, which indicated otherwise.

The graphene space is very large, there will not be one winner there will be many, and it is reasonable to assume that Versarien, currently the only verified graphene producer in the world and also expected to meet the emerging ISO standard, will be one of them.

super - is it flagged up somewhere that a particularly large 3d-printer is needed for the Brisol arch?

I know we have in -



“The size (of the "Bristol arch") is 5.5m in height and 4m in width. With our partners, Scaled, we can actually print anything up to 20m in length and 4m in width on their machine, which I believe is Europe’s largest 3D printer.”

but that could be construed as AECOM making the most of the "Bristol arch" trial to indicate that seriously large 3D objects can be printed by their UK engineering partner Scaled.

I reckon aecom know what they are doing...

"to print the product in the new graphene-reinforced polymer, which is supplied by Aecom’s materials partner Versarien. A UK-based advanced engineering materials group, Versarien has developed and manufactures the graphene material for CNCTArch."

and...

"We are also trialling a new grade of concrete at the Graphene Engineering Innovation Centre and at a civil engineering institute featuring a graphene based material. These trials form part of our collaboration agreement with AECOM, along with a further four projects in China and the Middle East."

metis - yes, you're right. But then, why would you need a particularly large 3D printer? An arch that size could easily be printed in one piece by the boat-building printer, and that would surely save on construction and maintenance costs. The joints have no functional advantage that I can see.

I still think the story of this arch has a way to run yet.

Edit: perhaps making it in 2 parts with a joint at the centre would be the best compromise? That would certainly make it easier to transport...

jv - true enough, but if the cheaptubes.com graphene came from say Sigma-Aldrich, then I can assure you there's no industrial company on earth that would trust Versarien over S-A. One is a huge, highly successful, $3B a year US manufacturer of speciality chemicals, and the other is a loss-making producer of carbide tooling and cheap plastic components, with a tiny sideline in graphene, and a 6-year record of failing to deliver. Who would you trust?

Some more interesting reading.

Just close your short supernum you will feel far more comfortable then and less of a need for the not so subtle posts , didn't think you would stoop to that level.... you've changed 🤔

The arch in the photo in the above link looks to be made of 5 curved sections.

The arch in this next link looks to be made from 7 curved sections

We're all looking for concrete progress.Ingress of funds, strength of balance sheet.Disruption of processes - not my current account.It will happen , but I wrongly forecast Trafalgar Day, St Andrews day closes in, St Stephens Day is a must.Off to the Apple Store on Westfield.

[johnveals] 22/11/2019 11:45

If you are going to use graphene enhanced concrete to take advantage of its increased strength etc to create stronger, lighter structures using less material then you had better be damned sure that it is the real deal and executed to the highest standards.

Failure to do this would result in yet more ticking time bombs.

[supernumerary] 22/11/2019 11:38

metis - this is old hat. As I pointed out ages ago, the IG graphene was purchased from cheaptubes.com :

'Same exfoliation speed and time were used for the industrial grade 3 graphene nanoplatelets (supplied by cheaptubes.com)'

I haven't re-read the paper, but I seem to remember this grade produced the best results for some important parameters.

While you're here... after further consideration, I'm not sure the technology in the Aecom patent was used to build the actual arch. The patent describes a building block approach, but the real arch appears to have been extruded in its entirety. Why would you need 'one of the largest 3D printers in Europe' if you were only doing relatively small components? Can you shed any further light on this?

That's rich coming from you teepot! :)

[davemac3] 22/11/2019 11:32

I've asked Neill on Twitter about this

[1teepee] 22/11/2019 11:28

I'm glad the nutters have this thread;)

[luckyorange] 22/11/2019 11:17

Yes they do Dave with the Cambridge Graphene Ink process but I suppose the biggest risk doing it in situ is the cement dust messing up the machines but good luck to them if they can get it all set up.

[biliwave] 22/11/2019 11:16

I'm talking about the tripe that fake bill wave posts on here on a daily basis that you give credence to.

[1teepee] 22/11/2019 11:15

The ink silly billy;)

Is the new log burner still coming this weekend Neil Ricketts? Wink wink nudge nudge;)

[ashehzi] 22/11/2019 11:12

DaveMac3, we will buy them, don't worry!

[davemac3] 22/11/2019 11:07

It is highly significant that the University of Exeter method produces graphene in water that can be mixed directly with the concrete mix. From memory VRS's patent (Ulster Uni) exemplifies graphene production in DMF, probably useless for concrete. So key question, can VRS make graphene in water?

[bbmsionlypostafter] 22/11/2019 11:05

2886.

???

What are you talkibg about?

[metis20] 22/11/2019 10:59

If the method used in post 83994 can produce

"an increase of up to 146% in compressive strength, up to 79.5% in flexural strength and a decrease in the maximum displacement due to compressive loading by 78%. At the same time, they found an enhanced electrical and thermal performance with an 88% increase in heat capacity.

Moreover, they proved a remarkable decrease in water permeability by nearly 400% compared to standard concrete."

then it will be very interesting to know what improvements can be made to standard concrete by the addition of Versarien's superior products.

I know I'm schizophrenic. And so am I.
