I just found out about this video this dawn. I tried to watch videos related to my thesis, but in this video, I woke up; kuddos to you sir, I laughed at the sudden outbursts of your sense of humor, here I enjoyed learning.
Thanks for your videos Sir. I am a visual learner and your videos make everything on paper make sense. I just started a new position as Concrete Technician and this is so helpful. Thanks again
Dr. Tyler Ley, you are doing a great job, learnt many things from your lectures. My question is "why different countries use different concrete mix design methods?" Is it possible to have a unified/universal concrete mix design, applicable in all countries, in all conditions?
I've just discovered that you can not only add colour to concrete (oxides) but glitter too, just before you seal it, both available from a company called 'Hemway'. I loved concrete before, but now it sparkles, I'm obsessed.
Dr. Tyker Ley, you are doing an amazing work. I learned so many things here than elsewhere. I am working on construction materials. Thank you so much. Could you share related resources on concrete., mix design, shrinkage, ...etc.
Working my way through all your videos and enjoying all of them. Do you have any information on incorporating clay into the mix? I am creating a large thermal mass for underfloor heating and want to use the excavated material within the concrete mix. It is made up of sandstone and clay so I am happy using the sandstone but not sure about clay. The technical department at the cement manufacturer just give standard "do what you want, we take no responsibility" statements.
What about cementitious material contained in the fine (man sand) and or course aggregates? I find this inconsistent absorption factor destroying my target water. Please do a video on this. Thank you and love your work :)
Ok.. if I am using a general build type, such as 1:2:4 and want to add fibers and water reducer, for use in forms for walls, how much fibers, how much reducer, and how much can I reduce the water yet get flow? Area is using hand mix or small mixers, sand, and 94 lb bags of cement... so need to figure it out..lol...
Hi Tyler, love your videos, i work in the building trade and have found your videos very good for understanding the materials i work with on a daily basis. But i have a question involving fly ash, i recently came to learn that fly ash is added as a partial cement replacement to make use of the excess calcium hydroxide produced in the mix, i am interested to know the reason why calcium hydroxide is not added so that more fly ash can be included in the mix. the reason i am asking is because i imagine this would make a nice creamy mix with all the extra binders included plus get rid of more of this waste material i.e fly ash? hope this makes sense and any advice you can give will be greatly appreciated and keep up the great videos 👍
i dont skip the ADDS. For paying u. coz im poor man. but i dont give up to learn, im from indonesia, Very great to meet u channel. btw, sorry for my english its so bad.
I do not speak English very well, but with the subtitles I can understand everything, I have not found in Spanish a video like that, fantastic. I would like to ask you a question, I am interested in looking for more information the method of fineness module of the combination of aggregates or optimal fineness module, through tests this method gives more workable concrete. Will not you have some biographies in English that you can recommend me about this?
Thank you Luis! I have been talking with some people to translate some of my videos to Spanish. If you have any recommendations that would be great. Fineness modulus is a very old concept (1918 I believe!). I would recommend using the Tarantula Curve to optimize concrete mixtures. You can find more info at www.tarantulacurve.com and ruclips.net/video/V-r4-9OcuyY/видео.html Let me know if you have anymore questions.
Thanks so much, I'm going to check your recommendation, It's going to help me a lot. About the translation, I could help you with the translation of this video because I've taken notes in spanish for all video.
Thanks for the video. Great stuff. I've a question. How would you go about designing a concrete mix that can withstand heating (upto 500 degree Celsius) and cooling cycles on a daily basis without failing under load?
Hey Tyler, when you were mentioning the percentage ratios of the raw materials, were you mentioning them in terms of bulk density, specific gravity or weight? Thanks.
100% air does not make finishing easier. In fact finishing concrete with high air is terrible. It just tears as you try to seal it up. The only way is to saturate the top...which is not good for the durability. I’m no engineer here just a concrete finisher that’s seen a lot of mix designs made in an office. Love the video by the way. Very informative.
Fantastic explanation on concrete. What can I use with a superplasticizer that will make pencil thick cement rod not break if dropped? Maybe something that gives it more flex?
A Doc, your a concrete lover... as am I... An idea for a video for you, fiber vs metal fiber and the disadvantages of metal fibers as points of rust and expansion in those metals... as they cause ''failure"... Especially, in salt and freeze thaw cycle areas... I am just sharing, as I know we need ideas as RUclips creators. (As I am stuck on stupid with the FIU Bridge collapse -- it is owning me right now... )
Compression testing would be awesome data... if, you can source some... looking forward to your findings... ty I did find a "block of ''cement'' video", with 7 lbs of fiber reinforcement... They just used a jack hammer... and added 7lbs of fiber (long or short, I do not know) and it resisted a significant amount... Of course, that was not a controlled test.
I will see what I can do. Steel fibers are becoming less popular and the stiff plastic fibers are becoming a lot more popular. I think a video would be a good idea.
Stiff plastic fibers, I am not up to speed on... would be enjoyable... Of course, knowing their drawbacks... Hmmm. I wonder how heat would deform them and cause "weakness" and same for freeze cycles... would they suffer from "plastic fatigue " (metal fatigue)...
Heat can melt them. This can be a good thing though as it allows the steam out of the concrete before it causes explosive spalling. The stiff plastic fibers seem to have good durability. I reached out to some friends and have some fibers coming in the mail. I will see if I can get some data with them for the video.
1:51 It looked like you said it, realized what you said, and kept on trucking like it never occurred to you that you may be talking about penis... lmao
S40 20 100 OPC TRIM 10 how can read this receipe i m Accountant i want to how in this recipe how much cement involve and other material? please help me
Hi there I want to mak a diy concete kitchen coutertop in a melamine mold about 2 inch thick reinforced with rebar. Quickcete 5000 is a wery popular mix for this aplication. Unfortunatily where i live (in Romania) these kind o concrete mixes are not avalable. I did find two kinds of potland cement, one with intitial high strenght the other with high final strenght. Also i found a liquide aditive for concrete. The label sais it is used to encrease workability. reduce amount of water and make it water resistent, along with dosage. I found some proportions for the kind of concrete for a slab, pawement and structural beams or pillars. I need some help figuring out the corect recipe for my aplication. Thanx
I am not an engineer but just curious are you guys still memorizing these things? Who does that in the era of automatic calculators that work together with databases and cloud services? I am guessing many engineers don't even bother to memorize these things and maybe simply use a specific software that easily calculates everything for you by taking all the inputs you provide and in return gives you a list of all the material and even the steps and procedures to be followed by even connecting to global services to find the lowest cost products in the current markets that helps you to prepare the best and most cost effective concrete you need. If that software doesn't exist yet what a pity for humanity and what a shame for all the brains wasting their energy in silicon valley. Please someone tell me that this kind of software exists..
I love how you said "creep" and then I asked myself what creep was, and at that moment you asked the same question and explain. Awesome!
You had me at "Welcome concrete superfreaks" :)
This is how Engineering is learnt!!👍
Thanks Danish!!!
Thank you Dr. Tyler .
Much respect and appreciation all the way from Somalia. 🙏

thank you sir I'm pump truck operator and everyone blaming my cause no one undersand about concrete
That does not sound fun. Let them know the truth!
No problem! Please let me know if there are other topics that you would like me to explain.

This guy is great. Thank you for sharing your knowledge!
It is so good how you presented it. It makes all the difference when someone with practical experience is teaching! Thanks a lot.
Thank you!
I love this channel
Selling your customer air 🤣, don't know y I found this so funny
I've just discovered that you can not only add colour to concrete (oxides) but glitter too, just before you seal it, both available from a company called 'Hemway'. I loved concrete before, but now it sparkles, I'm obsessed.
Thanks so much for sharing!
Very articulately put. Shades important aspects for students. Thank you.
Tyler, you are the biggest nerd I've heard. It is the the highest 2nd highest praise I can give someone.
This video is so clear and educative

Thanks 🙏 👍👍👍 nice video about basic understanding of mix design
What about cementitious material contained in the fine (man sand) and or course aggregates? I find this inconsistent absorption factor destroying my target water. Please do a video on this. Thank you and love your work :)
Oh yeah
You nailed it 👍
Your the best for sure always rescuing me
thank you!

Nice and Informative!!! Please make a Video on Life Cycle Analysis of Concrete and Durability of Concrete.
Bappi - Stay tuned! I have videos over both coming up.
I LOVE your Videos. How does "Fluide Mechanics" effect the mixing of Concrete or Visa Versa?

Keep 'em coming
Will do!
THANKS FOR YOUR SHARING - FROM VIETNAM
We would be glad to hear about FERROCEMENT.
Please make a video on it.
With lots of love from India.

I enjoy your presentation and methods of teaching.
Thank you!
To the best of you knowledge what is the best ratio for walls in a house?
Hi Dr Tyler! I love your videos! Do you know anything about use of Propalin as an admixture? Thank you
Any idea where one might find the mix of cast stone?
Thanks for the video. Great stuff. I've a question. How would you go about designing a concrete mix that can withstand heating (upto 500 degree Celsius) and cooling cycles on a daily basis without failing under load?

Dr. Tyler, is there away to get in touch with you for advice on making a formula that suits a very special need?
Fantastic explanation on concrete. What can I use with a superplasticizer that will make pencil thick cement rod not break if dropped? Maybe something that gives it more flex?
Can you add fibers to it?
wow amazing explanation.
Thank you so much!

Could you pls make video on design mix based on Eurocode
Fk😳😳 Your work is amazing 😳😳 thumbs up!!!

Does not exist. Local practices and materials make this challenging.
Learn how to talk. . , listening to this guy is very irritating.
