Can someone help chime in on this. I'm very naive about concrete. At my house I poured 3 raised garden beds (floors & 14" walls) Used rebar on 2 of them & not on the 3rd because I ran out & longevity wasn't super important to the wife. All forms were left for 1 week, concrete all the same (sakcrete high strength concrete 60# bags). The beds with rebar both failed and cracked after about 10 years. The one with zero rebar looks brand new like the day the forms were removed. Is there any scenario where certain type of rebar reacts to certain type of concrete to accelerate failure? I'm so confused on this one.
Thanks Luis! I will see what I can do. Joints are complicated and the best way to explain them is with strut and tie modeling. That takes several videos to explain. =/
Love it! as a builder, I like to know this shit. Would love to know more about how rebar in columns work, if you ever want to do a video on that some day. I see commercial stuff going on and rebar for columns look pretty complicated. Always been curious as to the methodology.
Yes, I am doing a frost protected shallow footing in Kansas and well, there`s wind,..so yes this helped me...….I will have the hardest to pull out worms ever,...I mean anchor bolts.
Thanks Tyler. Wish this subject was a compulsory module when I was studying mechanical engineering in Australia. Unfortunately, concrete and associated theory was just skimmed over. 👍👍🇦🇺
Thanks for the video! I have a situation with my garden walls, that has led to the following questions: The render has started to peel off due to rusting grid reinforcement that was put on the chest-high wall to hold the render. What's your opinion on reinforcement in such low-load applications? Is it necessary? Are there better options to prevent the render from peeling off in the future? Thank you
Thanks! 3D printing is going well. I know we need to get more out there on this. I have a series of topics that I need to get done first. Thanks for watching!!!
man...you are top professor in your field and .... not metric units.....thumbs, pines, foot, cucumbers...and so on!! SI units...please at list in engineering channels! :)
" Municipal Grade Concrete ' did not use rebar [or any other structural strengtheners] yet it was Nei indestructible. Able to withstand a nuclear explosion without failure. Why don't we use that now ? Since Rebar is the main reason water permeation is so destructive to concrete that has Rebar. Iron Oxide expansion. PS: what was the mixture for that concrete ?
Is it possible to achieve self-compactibility with low Cementitous materials? Actually I have researched at self-consolidating concrete in hot environment
Consider a series of children's books - Worm 101, 110, 200, 220, 315, 330 etc... by the time dad has read and re-read this series during their growing years they will be allowed test-out credits at OSU for their degree in Concrete. Engineering... lol... Even better would be the digital online books read by Dr. Ley... Sweet!!!
There are few people in life that enjoy anything as much as you enjoy talking about concrete. Thank you.
That's awesome, hope to hear from you soon about *resistance of basalt fiber-reinforced concrete to chloride penetration*
Thanks so much! I talk about FRP and basalt rebar here:

Thank you Dr. Tyler, great explanation, I have been watching many of your videos to get a good feel for proper concrete design.
Can't afford civil at 37 years old but you make engineering sound so simple
Thank you Dr. Tyler, great explanation.
great video man. Your students are very fortunate. 🙏🏾 Subscribed
I agree, slimy was awesome and so is this video!

The worm analogy is cute. I want to know about concrete made with fiber fillers and micro aggregates for water proofing
Fantastic Video! I feel partly responsible for this!
How can I bend basalt rebar? I thought it's more.. snappy? I don't think I can do the hook-think with the basalt-rebar.
Hey Tyler. Nice video, can you make a video on joints used in concrete structures??. Greetings and keep up the good work
Thanks Luis! I will see what I can do. Joints are complicated and the best way to explain them is with strut and tie modeling. That takes several videos to explain. =/
@@TylerLey 😊
I thought that I was freak to compare bars with worms. I'm sorry glad to watch this video, thanks Tyler
Thanks for watching and for being a fellow freak!!!

Berky - Look for a video next week or so. Stay tuned!!!
@@TylerLey btw, your videos changed my concrete life. Let's just say I love concrete. Now I'm knowledgable about and love concrete.
Thank you.

Nelson pins?
Wonderful sir
Thanks Tyler. Wish this subject was a compulsory module when I was studying mechanical engineering in Australia. Unfortunately, concrete and associated theory was just skimmed over. 👍👍🇦🇺
Thanks so much for the awesome compliment! Concrete should never be skimmed over!!!
Well, maybe when it's getting finished to look pretty right?

Fantastic explanation 👍.
OFF TOPIC...What's going on with these 3D printed concrete houses?
Thanks! 3D printing is going well. I know we need to get more out there on this. I have a series of topics that I need to get done first. Thanks for watching!!!
You are awesome 👏
Yes indeed.
Am making a separate playlist: Concrete -- Development Length
How can I get a paper published in cement and concrete research? That’s my question during my whole PhD life.
It depends on your topic! They have a certain style of paper that they are after. What are you studying?
I hope I explained things like you to my subordinates
I love this guy. 😅💜
man...you are top professor in your field and .... not metric units.....thumbs, pines, foot, cucumbers...and so on!! SI units...please at list in engineering channels! :)
This video is full of SI units! and WORMS!!!!

What are you referring to when you say municipal grade concrete? What was the location of this concrete?
Thank you very much professor. Could you please tell us about Self-consolidating concrete in details??
I will be glad if you do it.

@@TylerLey Teach them early and they will have it all their life...
You are genius
Worms are pretty cool. But you know what's better: a mustache.
Last time I was this early, I got a worm...sorry slimy
How did it taste??? Thanks for watching.
