So good to see you back! Great video!

You have my attention Tyler! Great explanation on the CO2 binder conundrum. Concrete. Can. Become. Sustainable. Now that’s an achievement.

Hi Tyler, really wanted to thank you for making and sharing this with us all on KZfaq. I'm in Australia and have taken a big step in my career from just testing Concrete, Aggregates and Soils in a Laboratory to becoming a Technical Supervisor for a large company. They are giving me further training in my new role. But your videos are great, I find your content very helpful and engaging to watch. I've learnt alot just from you. Thanks 🏆

Dr Ley!!! It’s been awhile we missed you! ❤️

Good to see tyler is back :) 👍

Thank you very much, Mr. Tyler.

I missed your videos, glad to see this one!

Your videos are very informative. Thank you.

Welcome back professor.

yoooooo welcome back man!!! missed you and hope you’ve been well!!!

Great video, Thank you

Grande Taylor ley, bastante interesante tu conferencia de secretos del concreto reforzado en el ENACE, muy importante la explicación de el uso de dosificación de la microfibra y macrofibras un saludo desde Saltillo,coahuila México, I LOVE CONCRETE!!!!

I love your explanation. thank you prof Taylor

This is good stuff... I'm just in the process of designing a new structural concrete home, and wanted to be able to answer the "but concrete creates so much CO2" naysayers... this video dropped at exactly the right time!

you are the greatest. you are an idol for a junior lecturer, to me. most of the time concrete is considered non-environmentally friend building material mistakenly. it's the scapegoat of building industry. it's the most common building material, therefore it's not surprising that it's responsible for 5% CO2 emission annually. probably any material with heavy usage will result in with that amount of CO2 emission. if it's optimised, it has the potential to be environmentally friendly (with utilization of SCMs, aggregates, as you mentioned). people have a bias towards concrete. but thanks to concrete freaks like you, this may change in future!

Good video and watching your video after a long time!

Thank you for the tools

welcome back, iam glad your back

Hi sir! Thanks for great video. It'll be very interesting to highlight your opinion about protective solutions for aerated concrete from carbonisation and etc. Anyway good luck!

All your videos are awesome

Hi Tyler, great videos. Can you please talk about crystalline concrete admixture. Thanks

sidewalk around earth 1300 times a year?! Love your passion, I just got a job in reo

Hey Tyler. Why dont you do a video on your recommendations for say concrete mix for footers, slabs, stem walls, basement walls. Like what mixture and additives you would put in or not have in the mix if you were pouring

Great videos. Im a grad student, I really enjoy your channel.

Thank you man!

Tyler! When are you going to tackle fabric formed concrete? Always great content, thanks!

Tyler, love the videos. Can you address slab curl and how to reduce it? Thank You

Pls do tutors on weekly basis 😊 Really informative

Missed you. Thanks

Thank you for the video. I know it is off topic for this video but can you do a video on concrete stress strain behaviour being influenced by testing machine confinement? Thanks

Thanks Bro 👍👍

Dr tyler can you please do a video on your favourite textbooks on reinforced concrete design? Thanks

Awesome video ..I researched on how to make fibre cement planks ..but I couldn't find any information on how to cure it ..should I water it like I do with normal concrete or just let it be?

Great video and info. Check your info at 13:22, two different sets of numbers.

Great video Tyler! What do you think about RCA recycled concrete aggregates for sustainable concrete?

Great video as always! Thanks for your amazing content Tyler. I have a question. Couldn't we use more powerful admixtures in order to reduce the amount of Binder needed? I mean, for example, use some Concera (from GCP, I don't know any other brands) to enhance flowability and cohesion while reducing cement and maintaining slump and strength.

Yes!!! Go Tyler! Such a great summary. Do you have a source for those fly ash / slag quantity targets? Are there disadvantages to using that many SCMs to be wary of?

I love this guy. I used to know precisely 0 jack about concrete. Now I see it everyday in a different light and all thanks to Prof Ley. Incredible what a passionate man can do with a curious mind

once again an amazing video. Can you plz make a video on engineered cementitious composite (ECC)

Hi Tyler, I am building a house in Australia, I will be using a concrete slab as the foundation. Can you give me a list of the most important things I should consider/do?

Have you done a video on sealants? Just read about crystalaline sealants. They know why roman cement works the way it does, I think one of your early videos talked about crack size.

This may be off topic but building pickleball courts is a big thing these days. From what I have studied is Post Tension Concrete the best products or are their cheaper ways to have a long life community court with low maintenance, long life and crack resistance.

Can you make a video on how to make the mix for the making of hollow block with vibration and compression and hydration percent for high strength?

Do you have any videos about adding rubber pieces to the mix? Sounds weird and interesting.

what you think of geopolymer concrete?? better than standard concrete by far!

Do you have any videos on "air crete"?

Glad your back!!! I have a video suggestion or a suggestion for your class experiments. The farmers almanac has best days to pour concrete, can you run some tests and see if there’s anything to it? And see if you can figure out why it’s better, if it is?

Hey sir, can u please make a video on partilal replacement of cement with rice husk Ash. I wants to make concrete hollow blocks with more strength at a reduced cost that's why you as a professional. Thank u, may Allah rewards you.

Hi sir Can you make video on some new technologies? (Eg Mivan technique) Please do if get time that would be really helpful .

Hey mate, Do you know if it's possible to lay a non self leveling mortar at 2mm (about 1/16 inch) thickness Would adding microfibres and latex help?

Could you tell about concrete boats?

I'd imagine that the energy required to make the concrete is what causes the vast amount of CO2 because concrete is so energy intensive so this could be a really good candidate for renewables because it's probably made mostly during the day and finding things that use a lot of energy that can directly be replaced with renewables without the need to store power is probably the only path forward for renewables because storage is so difficult and expensive.

How do I fix crazing on a concrete patio that was just poured?

👍✌

Tyler. I'm a PITA and I know you're not likely to answer this question, and if you do, you might be concerned with your liability. Please understand all I'm looking for is general advice, not design advice. Hopefully you'll consider it.. Here we go. I've got a 42 inch block foundation under a hip roof garage that's bowing outward on 2 sides. Don't think it's much, if at all in the last 8 years. It's shifted away from the slab about 2 inches in the centers. It was built 50 years ago. The estimates to have plates on the exterior with threaded rod running in to ground anchors under the slab and then poured over similar to a pier are $7,500ish. Too much. My thought after 3 months of dreams and wandering thoughts, is to drill 3-4 inch holes in the plate, fill the block cavities with 1 1/2 bags of Quikrete with 2 fiberglass rebar buried and a full length allthread coming up through the hole in the plate. Then I've got 2 choices. Drill through the filled block horizontally, bolt it to a 10' x 10" plate on the outside, and run it through a bracket that's been cone anchored to the slab floor. Tighten the thread rod holding the outside plate to 80 lbs. Other choice: Bolt a bracket onto the allthread coming out the hole in the wood plate capping the filled block. The bracket would be L shaped 1/4" steel bent downward toward the slab, then place another L shaped bracket anchored to the slab, run allthread through both brackets, put a bolt on each side of the brackets and tighten to 80lbs. The top of the plate to the slab is about 5 inches, so not entirely lateral force. What do you think, and which might you consider using? I will have one follow up question following this, if you are actually willing to respond, which I'm sure you won't, and I don't blame you.

Good afternoon Tyler. If injecting carbon dioxide into the cement makes calcium carbonate then why is that any better than just adding in calcium carbonate rich mineral in substitute for cement? Is adding the unhydrated powdered limestone an equivalent effect. Maybe the purity of natural minerals content of calcium carbonate vs the calcium carbonate formed via C02 injection is a factor in the end product? I must be honest I am a skeptic with this technology not because of the science but because of the business end of this. Tracking where the Co2 came from and its own manufacturing carbon footprint as well as it's accidental release to atmosphere is concerning but maybe I just need some guidance. Thanks for any help with this topic. Best Kevin

I loved your last video where you said, you were a concrete Fa reek, that was hilarious

Hi,is it possible to produce UHPC with this electric mini collomix mixture?

I want to make a large light weight flowerpot with concrete. Can anybody give me a formula for the concrete mix? Is there anything that I can add so that it will not crack? Thanks in advance for your help.

I doubt when you say 90%of co2 comes from binder alone, this may be the case if we use only portland cement but if we change the binder composition reducing the co2 emission, contribution percentage will come down from 90.

I DO have a real question ""question of recycling of concrete " you have no video of that

the link of your website is not working. can you please check it?

Very nice your chanel, but you could talk slower and reinforce the conclusion because I understood but not absorbed immediately ! I want to tell my engineer what i want!

I guess I'm also a concrete freak : )

Concerns about toxicity of contaminants in SCMs for interior spaces?

Still waiting a video on foam concrete aka cellular concrete

MMmmm ?? any way nice weather

How to obtain unobtanium. 🙃

I sent a email to you using YT email you have, please check for the email in junk mail, it will be under Hemp@ And thanks for your videos, even if I do not hear from you...

It's good to care about the earth but we should not worry and turn things into a religion...there are many things that we don't understand about this life. I trust God, He's in control.

Sounds expensive, shoddy, and/or deadly. One of those inevitable triadic compromises engineering cannot resolve. A tournament of unearned risks. I'd prefer Fermi estimation to Einstein's spreadsheets.

I think solving the CO2 budget is a solution looking for a problem and the "solution" has huge costs and problems of its own.

How to make dogshit. A book by a man who has never had to lay a trowel on a floor. Your talking about a 20 year old fly ash mix. Use some glass for your fines, some polymer admixture to lower you water content. Look to the countertop mixes for more sustainable designs. This guy is stuck in 1995.

I already gave video a ✌👍🧱a long time ago

It's nice to meet someone with the interests 🧱👍
