- This video covers 5 proven strategies to make green concrete. Green concrete is starting to be in high demand and it can be overwhelming if you have never done it before. This video gives you 5 proven strategies that I have used on commercial projects. I also include two case studies where we have used these strategies and I provide several key details.

Who wouldn't want to make the world a better place & make awesome concrete ??!
YASSS!!! I agree.
Thanks for highlighting our MEGASLAB work, Dr. Ley! 👏👏👏
Thanks for the comment!
Hello Sir, Please create a series of retaining wall calculation videos. Thank you
Thanks for the video 👍
Thanks for watching!
What if... we use the molten salt that cools a nuclear plant... to fire a kiln for portland or other ingredients? lol
Nicely done! 🤝
Thank you!
Informative! Thanks for sharing.
Can you make a video on carbonation technologies? E.g., carbonation curing, accelerated carbonation, carbonation mixing, mineral carbonation
Sir,can we use wood ash as subtitute of fly ash?
How about C-Crete Technologies strategy?
Great video Tyler! Have you've done any work with graphene yet? I was wondering if you need to pump concrete if using graphene can reduce the amount of paste.
I have done a little work with graphene but not a lot. I think the jury is still out on what graphene does in field concrete.
First up, tried explaining this to my sister a green ministers aide....oh that's too hard.
Good luck!!! Just send her the video. =)
I will and she may even watch as you are a PHd, but us plebs know nothing. God forbid I've built subdivisions, roads and sewer systems, but my education doesn't measure up to hers, so obviously I'm beneath her. Never mistake education for intelligence.
Respected Sir, The site leading from the link, is not working. i entered my email address but nothing happened.
Thanks for the note! I am trying to get this fixed.
It should work now!
Geopolymer, if applicable (gotta test). If not, CEM III/B.
I have tested geopolymers. They can do some cool stuff but they are very finkicky and tough to get to work in the field. I don't think they are practical yet.
@@TylerLey Wagners EFC has gotten certification in Germany and Australia. Seems like we're getting closer to it becoming much more widely used.
Lmk if u down still
Wouldn't having the concreate be as cheap as possible and last as long as possible be the most green? If you have a better mousetrap then you don't need to label it "green" to sell it.
Long lasting is the right approach. Carbon footprint is also important. Typically things with low carbon also are low cost. At least for now.
I wana talk wire mesh and rebar
I cant comment w main channel
Asphalt per ton CO?
Parking lots roads etc mostly asphalt.
Subslab soil compaction is critical no clay organics . This will allow reduction in slab thickness without subsidence.
Many foolishly skimp on proper floor slab soil and compaction.
Meanwhile China ,India etc total disregard for environmental laws..
Do you have any data on using Beach sand coquina as aggregate ?
We do sea walls in Bahamas and not much approved sand gravel .
Large mass walls docks i want to try fiberglass fibermesh and fiberglass rebar in salt water marine applications.
China is burning 4.2 billion tons of coal each year, and producing 1 billion ton of steel. India is right behind, and increasing even faster.
You can use beach sand in concrete but it is typically pretty fine. You need some coarse sand particles as well. You could get this from rock dust.
I think fiberglass rebar could be a good choice for sea walls.
@@TylerLey Salt in sand affect chemical reaction hydration ?
Navy Sea Bee have old studies on this.
Could be a good to look into this in tropical island areas no rock or good sharp edge sand locally.
Be careful to rinse away salt from your aggregates, especially sand.
Ok Tyler, do a Long term study on wear comparison of concrete that has been repaired during installation, either a boot step or tire track, and regular untouched area free of disruptions.
Also has there ever been a study of durability between equal tests of concrete during different moon fazes, be it full moon vs less moon?? Would it make a difference to the moisture content?
Q1 - People have done this in Minnesota on MnRoad. This is where you can make experimental pavements and then divert heavy traffic on them to see how they perform. They do great.
Q2 - I am not sure I am tracking. I don't think it will make a difference.
Do u rem what i asked u?
Hey bro, you ever heard the Gospel? I think you'd make a great Christian.
If you feel good about these things, have in mind, China is burning 4.2 billion tons of coal each year, and increasing fast. India is burning 1 billion ton, and increasing even faster. So what is the point really, that we are saving a few million tons of CO2? Not much, not much at all.
Then let's all jump off the bridge. What's the point really? 🤷
I try and give people what they want. There are lots of people that want green carbon concrete. If we can provide it for them and also make some high quality concrete then everyone wins.
Unfortunately, I think this project will increase the total CO2 emissions - the total CO2 emission will increase. Reason is, now people will save a lot on their concrete work, and concrete will be more competitive, and people will use even more concrete. So when we only look at the emissions, they will increase.
We see this with cars too. Cars are using less fuel than they used 10 years ago, and many are now electric. Still, the oil consumption has globally increased with 10%, from 90 million barrels a day to 100 million barrel a day.
Some of the things that we talked about in the video reduced the amount of concrete used by increasing the flexural strength or changing the structural system. If concrete becomes more competitive and is used in a higher volume then that is a good thing because this concrete will be a long lasting structure for a great value.
No rebar? No fn way. Who’s gonna pay out on that law suit. Carbon footprint ain’t worth ship if your repairing failed slabs.
You should see the performance with fiber reinforced concrete. It is really impressive. Slab on grade don't need a lot of steel in them. There has been fiber reinforced slabs with no rebar in place for more than 20 y in heavy use areas and they work great.
