How Graphene Could Solve Our Concrete Problem

Is Graphene the Future of Eco Friendly Concrete? Get Surfshark VPN at surfshark.deals/undecided and enter promo code UNDECIDED for 83% off and 3 extra months for free! Graphene is considered one of the most important breakthroughs in material science since its discovery. This “wonder material” was widely overhyped, and still hasn’t lived up to its potential. But since my previous video on the truth about graphene, we can now see more concrete and realistic applications hitting the market - not those out of this world promises like the space elevator. What if we could cut down carbon (CO2) emissions from cement production by 20% and make cheaper and more powerful EV batteries using graphene battery technology? Is graphene finally starting to deliver on the promise? Let’s see if we can come to a decision on this.

Will concrete embedded with graphene eliminate the need for rebar?

[@ManxAndy]

@@Cat-qw4ir I don’t think so, it still need the torsional strength of the rebar, but it does reduce the amount required, plus it has corrosion resistance 👍

[@yankee1376]

But...didn't you just tell us Borophene has already made graphene old and busted?

[@JohnDewar]

When you describe the benefits of graphene in concrete it really sounds very similar to the benefits of mixing in asbestos. Given the tiny particle sizes I hope someone stops to do a cost benefit analysis on potential health impacts and the impact of future abatement strategies and costs before this gets widely deployed. I feel like industry would love to spread millions and millions of tons of this stuff around before safety regulators catch on. Carbon nanotubes have the same problem I see people playing with it like the ultra black paints which are super cool but fragile and I saw a study comparing the inhalation risk in rats of nanotubes vs asbestos and it was at least as bad but likely worse. It makes intuitive sense that nanoscale indestructible fibers would not be good for our lungs.

[@zesky6654]

Thanks, I'm terrified now.

[@slanew]

I came to express my same concern. I'm excited about the applications, but worried it'll be the next big carcinogen.

[@RobBCactive]

Carbon graphite has been around a very long time, it proved much safer than lead pencils and has been used as a lubricant. Isolating one layer by pulling graphite apart is not creating a new chemical and calling them indestructible is silly when the toughest form of carbon, diamond is burnt at a relatively low temperature. Carbon chains and rings are common organic chemistry

[@cam5376]

Graphene production at scale is subject to REACH regulations, just like any other chemical, and this includes toxicology tests which so far have indicated it is safe.

[@JohnDewar]

@@RobBCactive Thank you for your replay. I'm sorry that in my comment I was not as clear as I could have been since I switched subjects from graphene to C nanotubes. "Indestructible" was somewhat of a rhetorical flourish when I should more accurately have said "bioaccumulative". Of course the material can be destroyed industrially, but one of its desirable industrial properties is that it is highly insoluble in water, and when you process it you can end up with very small particles that your organs can't filter out and can get into your bloodstream. So if you release a lot of this into the environment it seems likely to create problems. Like PFAs/PFOAs, they aren't going to hurt you immediately probably even with high exposures, but it sticks around and eventually causes problems. It may be difficult to detect contamination and filtration may not be effective for the smaller particles that are the ones we need to be concerned about. Here is one study that concluded there is potentially some Graphene bioaccumulation possible: pubs.acs.org/doi/10.1021/acs.est.7b04339 REACH isn't going to necessarily help American consumers or people in Asian countries where it's being manufactured. REACH isn't done studying the material. They show that it doesn't exhibit acute toxicity but they do classify it as having long lasting negative effects on aquatic life because it sticks around. PFAs and silicates don't have acute toxicity either so I don't think we should let down our guard based on that. echa.europa.eu/substance-information/-/substanceinfo/100.227.924 I do not think that we should abandon the use of Graphene as it has lots of exciting potential but I am saying that we need to proceed with caution and maybe limit the applications so that we can control the pollution or recycle the material properly. And ensure that production waste streams are controlled. For example, not deploying it to residential construction where homeowners will eventually dispose of it improperly. After all there are still some industrial applications of asbestos that we have not been able to eliminate because of its superior properties...that doesn't mean it should be widely deployed the way that it was in the 60's.

[@gregalee]

My concern about graphene is its long term impact on the environment. We know, for instance, that precautions must be taken when handling graphene to prevent it becoming airborne and being inhaled. In sheet form, it is relatively stable and inert, but when we embed nanomaterials in products that wear, like the soles of footwear, vehicle tires, or concrete, we have to assume it is going to enter the environment on a very small scale during their slow breakdown. According to the European Commission adopted 2011 Recommendation on Nanomaterials: Fullerenes, graphene flakes and single wall carbon nanotubes with one or more external dimensions below 1nm should be considered as nanomaterials. We all know what a nightmarish threat earlier nanomaterials like asbestos, finely powdered silicates, and even today with micro plastic particles were all discovered to pose long after their adoption in industrial and consumer products. In addition to simple inhalation risks which are relatively low in the outdoors, researchers said that (as with asbestos and coal dust, and other smooth, continuous, biopersistent particles) graphene can enter the body and may have the ability to instigate tumour growth. There is minimal reliable environmental data on graphene regarding its bioaccumulation or mobility in environmental media. The way I see it, we need to do our due diligence researching and vetting these materials for long term environmental and human health impacts before we turn to them as a panacea for our carbon emission problems.

[@grn1]

Excellent point. The main uses of graphene nano-particles that interest me are in electronics where they hopefully won't escape into the environment though some precautions should certainly be taken since people do throw away electronics rather than recycle them (I've actually got a decent amount that I want to recycle but next to no options to actually do so, especially if I want to get something in return for the precious metals inside). Concrete is an interesting use but as you said we need to make sure the nano-particles won't cause any problems down the road. I've read about work on graphene sheets which could enable the creation of some really strong materials, not sure how likely it is for small pieces to break off.

[@jeremiah6462]

Great point. Thanks for your comment, I have been on the graphene train since I first heard about it about 6 years ago. You have given me reason to pause and think.

Graphene in my mind has moved from disappointing Back to exciting me , maybe because I dropped my expectations from when I first heard of it. I think now we have the right ideas for it, let graphene improve do all the little things that it can improve and as it’s use scales up it will start to do everything we thought it could .

Sony and Asahi Kasei released the first commercial lithium-ion battery in 1991. Before that it was just us playing around with materials and improving on the original design but even then we still looked at NiCad/NiMH as the solution because it did the job and it was much cheaper.. ( improvements like the implementation of a graphite anode, which replaced a soft carbon one and upped density levels, but wasn't feasible to make until the early 90s). wasn't really even until the early 2000s that we actually see them in normal consumer things like the original iPod in 2002 due to cost. Lion powered tools and such didn't see the light of day until the mid to late 2000s.(2005 Home Depot and Harbor Freight still pushed Nicad/NiMH tools for example) Energizer did develop lithium AA cells in 1991....but we wouldn't see those become popular until about 10 years later.

This is an exciting area of research and application. I actually recently became friends with someone who moved to our small town and works for a company developing graphene additive based concrete solutions utilizing low grade graphene. They've determined that the graphene dramatically decreases drying/setting time, increases strength and durability all the while reducing production costs and environmental impact. It seems very promising and is a cool new(ish) area of material research.

[@op4000exe]

For me, graphene was never unexciting. The issue with graphene is mostly that journalists and others basically imagined that it could be made, and integrated into our society in an extremely unrealistic timeframe. Heck even if you had the technology just the time required to build a factory would've fallen short on their unrealistic projections, thus people got convinced that it was all hype and no substance. Conversely my takeaway has mostly been that it WILL be amazing, but that we need to scale production first, something which it looks like is genuinely happening now.

The CO deposition method is interesting. I wonder how they go about separating from the copper substrate. One note is the supposed elimination of explosive gasses is inaccurate.

I suspect that graphene will be one of those products that becomes more and more useful in more and more products. However the expectations set by the over-hyping will lead many people to always feel that it has fallen short of expectations never mind the fact that it might end up making huge differences where it finds a foothold. It will always feel too little too late.

[@SophiaAphrodite]

I think the hype is merely at the consumer level. It appears industries are already using it in some forms more commonly than we expected and expanding into other industries and usages at a pace that can sustain the innovation, like upgrading the machinery, etc without significant sticker shock. I think the industries that benefit from it themselves will help innovate application methods as well making it more accessible for us.

[@ferfromla]

From what you presented here, graphene in concrete is one of the first uses that not only makes sense but can be manufactured at scale. If concrete can be made more environmentally friendly, robust, durable, and lighter, it will bring significant benefits to builders everywhere. It will probably take years to develop practical applications for the stuff that remains in the lab. Nevertheless, labs worldwide continue to research, and eventually, a breakthrough will happen that will fulfill the promise of this fantastic material. I appreciate your keeping us current with all that is happening in this space.

[@eris1427]

It's only make the concrete stronger and to some degree more durable but actually less environmental friendly. Hovewer, in some cases due to the increased strenght it can reduce the needed thickness of structures resulting in lighter and more environmental friendly structures due to less material used. This is not viable for all types of structures due to differ reasons and in some cases it's worth it and others not. In some cases there already are additives that gives the same result but cheaper. So it's not a total revolutionary material in the building sector but another possible solution to be used in the right situations.

[@eris1427]

@@Withnail1969 It does have the alleged effect and is already being used where it's beneficial and the extra cost can be accepted. The cost of graphene in sufficient amounts is high and it's therefore rarely used. We do have alot of studies on graphene reinforced concrete with good results and also have a good general understanding of how nano and micro reinforced concrete behave from other reinforcment materials. For example the increased fire protection comes from the reinforcement greatly reduces spalliation of the protective concrete layer when exposed to high heats (fire). The protective layer can therefore be reduced and the protection is more controllable. Today this fire protection is mainly done in large tunnels with polypropylene fibers but the same effect have been seen with graphene which is an interesting alternative due to the increased strength. Which would make the reinforcement have multiple purposes. But due to the price it's still far from a common solution in large projects and much further from being used in normal buildings.

[@ocadioan]

It needs to reduce its price from $100/g to $0.1/g to be attractive for most concrete uses. Clinker has a ton price of $48/ton, and reducing the needed clinker by 20% by adding 0.01% graphene at current prices increases the per ton price to $1038/ton. Except in extreme niche cases, it is basically unusable unless the price drops drastically.

Rice Labs also has an incredible graphene production method called flash joule heating, that not only produces graphene from any plastic materials but also elemental hydrogen and oxygen. They've already tested the method with Ford motors and created a close to perfectly circular recycling process

Indeed. Just to think that a mere 10 years ago it was still majorly on a lab basis, to now being decently commercialized. Commercialization is always the biggest hurdle with new promising technologies, and serves as the proof of concept that graphene is here to not just stay, but to evolve even further in the next decade. The vast majority of development of a new technology happens AFTER it becomes commercially viable. And that's where we are at now.

[@cv990a4]

Right, but I'd like to know more about possible toxicity. It's incredibly light and strong, so what happens if there are shards of this stuff flying around.

What happens if you breath that stuff, for instance?

For CO2 savings from improvements in concrete, you missed an opportunity to explain how improvements in compression and tensile strength drastically reduces the amount of concrete needed for a given project. If you need less because it’s stronger, then you also need less because the project weighs less. It’s a virtuous cycle. It would be interesting to see it quantified by a structural engineer.

also the amount of steel rebar should reduce if the material itself is stronger, so thats also a CO2 win

As an engineer, it makes me tired that anything new has to be used in critical systems straight away.

Graphene has not been over hyped, all of the potential applications are still potential applications, what has happened is over expectations of ease of development.

I think the hype around graphine was correctly placed, just a little early. Graphine has a huge potencial to influence engineering of products with its strength, and conductivity being key factors. The only think limiting the use of graphine currently is not technical, but ecomonic. Its producing it in such volumes that the cost is justified for the benefit. think of the grid cables example. graphine will only really be used in grid cables if the cost per mile of cable, is less than savings from the per mile efficiency difference with copper cable. over the lifespan of the cable. if a graphine cable costs double the amount. but only reduces transmission losses by 1/4 then its not going to be worth the cost. However if the graphine cable costs 1/4 more but saves >1/4 of the transmission losses, then everyone will start using it. OR if it costs 1/4 more. however has the same transmission losses but lasts twice as long before needing replacing. or any combination. so long as the economics make sense it will have customers. but whilst its expensive, very few are going to utilise the material.

[@paulferguson4930]

This is a critical consideration. The copper price right now is about $9,322/metric tonne. That comes out to just under $0.01/gram. Compare that to what Matt said in the video, that graphene prices have come down to $100/gram. If it requires the same amount of material to carry the same amount of power, then there is a real barrier to adoption here. If graphene is much more efficient, then the playing field will tilt more in the direction of level, but it will have to be hugely more efficient to get to level.

One of the first concerns that I saw when graphene came on the scene were medical studies of disease and cancer from inhaling nanoparticles. Which, fair. I don't know if it is or is not proven either way by this time? But regardless, I do know that I would be a lot more likely to trust graphene used in *internal* designs. Whereas use of graphene in concrete? A material we know breaks down over time? Even if that breakdown is an even longer time than the same product without graphene, that's still concerning. Whatever we do with this wonder material, I sincerely hope that we are not repeating the asbestos as a building material crisis for a future generation.

Revolutionary materials are never breakthroughs in and of themselves.

Also, if lowering C02 emissions is the goal, we always need to factor in the C02 produced in getting to that goal, which seems to be a question almost no one asks. It's part of why "green" energy solutions are rarely green. Electric cars have 0 emissions but creating them and their batteries creates as many problems as it solves. Graphene is no different. If all we care about is C02 emissions, we need to start doing ALL the math.

I was born only 47 years ago. In that time we have seen a bunch of exponential improvements in a wide range of things. This looks like another one. It's easy to forget how unprecedented it is historically to witness that amount of change in one life time. And I hope to live another few decades. My feeling is that things are happening faster, not slower. This graphene thing is evolving extremely rapidly. If anything, people seem a bit spoiled with their need for instant gratification and dismissal for anything that fails to yield results during their short attention spans. The ironic thing with graphene is that a lot of things happened while these people were distracted by other things and they are still peddling the same arguments as a few years ago, which are simply no longer valid.

Some applications propably wont work as well (foundations, waterproofing- if there is too much oxygen) Low- tech is a good solution for many things.

[@SkepticalCaveman]

It's actually possible to make space elevator on the moon with a kevlar cable already, because of the lower gravity. Even Mars should be possible, but Earth is very dense for it size so it might be just beyond the edge of being possible. Venus is significantly smaller than Earth, although only slightly, and might be just small enough. The surface of Venus is way too hot anyway, so building a space elevator down to the upper atmosphere of Venus (where both the temperature and gravity is close to Earth's) just makes sense. NASA have actually suggested that floating/flying cities on Venus might be an better option than Mars for colonising. Since gravity is close to Earth's, bone mass loss should be avoided much easier. Venus has also a lot of heat energy that can be converted into electricity and an atmosphere that protects against radiation unlike Mars. In summary, space elevators are still viable, just maybe not for Earth.

You can reduce the amount of clinker cement by just substitute it with flying ash or GGBS which is much cheaper and it already reduces the CO2 emissions of concrete. Also the increase in tension resistance of concrete of 27% is a bit of a nothing. Concrete tensile resistance is in a range of 1.5 to 3.0 MPa and that’s why it’s reinforced with steel, which tensile resistance is 200 to 500 MPa. So if you have to use graphene to make concrete stronger in tension from 3MPa to 3.5MPa is just a non-sense to me.
