3D printed concrete is a much better application 👍😉

I really do think that most if not all posters and readers of this BB are agreed that a number of distruptive posters are just terrible and very untruthful.

One should not answer them in any way - posting on this BB or even using Twitter. It has been said more than once that if you starve these people they will eventually go away especially if the shares were to jump, for what ever reasons back towards the 145p when Primery Bid last sold shares to us all.

There will be more good news this side of Christmas ......so keep calm and FILTER them please..........

Forget putting it into concrete

'Exeter University nanoscience and nanotechnology professor Monica Craciun told New Civil Engineer how the technique could reduce carbon emissions from concrete by around 446kg/t, calling it “a game-changer” for the construction industry.

“Effectively you can use less concrete to get the same strength that you would have with a normal concrete,” she said. “You can use around 50% less concrete; in that way you can have a significant reduction of carbon emissions.”

Craciun said the team is working towards securing a new British Standard for the concrete, which should be ready for commercialised production by the end of the year.

“It’s not expensive because the process is very simple. It is basically similar to a kitchen blender where you put graphite, water and soap molecules and you produce graphene,” she added.'



Neill posted a link up, glad that he has gone for the high end route , instead of 'not expensive'.

Occultusverum1, Agreed. I find the attitude of this particular detractor particularly offensive. How he has the audacity to think that Neill is his peer and should respond to his demands is beyond me.

On one hand we have an extremely well respected CEO of a company that he built from scratch and is at the forefront of technology and scientific discovery. A man who is respected at the highest levels of government and within the business world and is on the verge of taking his company global.

On the other hand we have a petulant child-like troll who sits in his pants for 13 hours per day typing negative garbage onto this board and twitter.

Staggering when you think about it.

Just bought some Goodride tyres here in South Africa, then Googled the company -

From nothing in 1958, to 10th in the world now, in an established industry.

If you take the pre-cast option you will reduce the weight of the section. This could mean bigger sections can be cast (reducing construction program) or the size of lifting equipment can be reduced (a mobile 250T crane will cost around £5k/day). More factors at play than graphene in, steel out unless you're a bit narrow minded.

[potsol] 22/11/2018 16:24

One of the most expensive and time consuming elements of an insitu concrete pour is the time it takes to fix the reinforcement not the actual cost of the steel itself. In addition good steel fixers are becoming a rare commodity, so innovative construction techniques are becoming a necessity.

"A monkey could replace Fox"

there's a conspiracy theory doing the rounds that one already has...

[borg45] 22/11/2018 16:20

[rafboy] 22/11/2018 16:19

Thanks Tim.

[borg45] 22/11/2018 16:19

You mean loglorry is a special needs person Tom haha

[tim3416] 22/11/2018 16:14

Its actually 124 to sell and 125 to buy at the moment not the prices showing


Edit - or can sell 150k online at 120p

[loglorry1] 22/11/2018 16:05

@serratia why would someone like AECOM take concrete which costs $100 a ton and add 0.02% of Nanene (at $35,000/kg) which is 200g/t costing 2/1000*$35,000 = $700 thus increasing the cost of the concrete from $100 to $800 a ton or by 800% ?

Further the could buy just 200g of PureGRAPH from FGR at just $20 to get an increase in strength taking the cost from $100 to just $120.

The Exeter paper which you thought was wonderful before here used higher concentrations. It's also worth saying that they made their own graphene in their work quite cheaply.

It is also worth noting that there is no academic work which compared adding graphene to concrete vs steel re-enforced concrete. I know a senior engineer who used to work for AECOM and he said the comparison needs to be done there as adding steel is relatively cheap and increases concrete strength dramatically. It's also well tested and an accepted practice in the industry. There is also work ongoing which adds steel fibers to concrete.

shhhhhhhhh

[jointer13] 22/11/2018 15:24

you have a very polite way of saying things serratia.

"The poster was either being mischievous, lacks an understanding or both."

keep up the good work serattia...its much appreciated.

Concrete -

I've been asked to add a comment as someone has made some silly comments. The comment was something to do with adding 1% Graphene to concrete mixes making the economics poor.
Graphene works by affecting the hydrolytic crystallization of the cement. It is not a reaction with rock and sand ! Cement is added at around 10% of the mix so immediately you need only 10% of the Graphene quantity you would use in a plastic. Addition rates vary with the type of polymer used, some 0.5% or less some 1%+. Scientific publications show an increasing strength with increasing Graphene loading but there is little benefit going above 0.04% This is confirmed where FGR say they only use 0.02%.

The poster was either being mischievous, lacks an understanding or both.

I wonder if our 300k super buyer has started? GLA

[jointer13] 22/11/2018 15:00

skylite.

hasn't the burger queen seen any coming and goings lately..?

"Just speculating on why lords cc for strategy meeting?"

Lords is the home of English cricket. One of the most famous English cricketers of all time is WG Grace. Ministers receive grace and favour apartments. Therefore NR is about to be appointed Minister for overseas trade to replace the hapless Fox.

Obvious really, when you think about it...

[scottishfield] 22/11/2018 14:35

Just in from my cycle, seems to have been a good interlude..

[ellissj] 22/11/2018 14:25

Just speculating on why lords cc for strategy meeting? Must be in honour of Roberto of Gnano because cricket is national game of spain ! ;) interesting. Or maybe just that it's 1hr from Heathrow lol ! Imo. Glalth. Best ellis

I heard ceramics and heat furnace coming soon maybe!?

Come on squire you can't get away with a statement like that. Who told you or are you just making stories up?

[occultusverum1] 22/11/2018 14:14

I think so too Lucky. We must be near to commissioning the new machine(s) and one would imagine fulfilling an order that the machines have been purchased for.
