I have been pouring concrete flat work and structural walls since 1986 I quit school and start at 16 and third generation Concrete and Mason and I’m 50 years old now got 34+ years in a breaking my ass made it to senior project manager many different times in the past five years and nobody ever fucking has taught me the most important shit about concrete and pouring concrete then I’ve learned from you in the past two hours since I find your channel I don’t know how much you appreciate a man and I’m taking myself back to school with you over the next year and i’m going to become one of the best and only concrete guys on the East Coast that still at 51 years old I’ll be I can put it down pull the stick on offload finish it hard trailer blown whatever it is and fucking tell you everything about the material so thank you again
@@TylerLey you're welcome. now if I only had the brain capacity to absorb the information. In one of your videos you mention that you want your concrete to have a higher Ph, what about using water with a slightly higher ph. do you think that would help?
Hi Tyler Do you have videos on the following topics ? 1. Thermal properties of concrete structures 2. The effect of thermal shock on concrete material 3. The durability effect high temperatures have on existing concrete. , does the rise in temperatures are shortening the life of concrete infrastructure ? 4. Is it possible to measure the water flowing through cracks ? 5. Repairing cracks with movement ? Perhaps in elevated slab ?
Sir Ley thank you for the very informative videos you are sharing. They're very helpful in my work. What I would like to know also are what are other causes of scaling aside from those caused by deicing salts, improper curing and finishing (I assume the condition you are talking about in this video is that the concrete is properly proportioned). What if the concrete is not properly proportioned but finished and cured properly? Will this also cause scaling? We don't have snow in our country. I ask this question because I have seen newly constructed pavements but scaled too early. Thank you very much.
Thanks for these incredible videos. Could you talk about cold joints? Is there any research on strength drop off over time or the impact of Concrete Bonding Adhesives and how they function.
Ryan, Good question. I would like to. I need a little more content on it. We are doing some things in the lab. I will see what I can come up with. The simple answer is to avoid that quarry or crush it so that you don't have big aggregates. Not a practical answer.
wow! I worked the surface too much and had too much bleed water at the top. The surface started chipping/flaking away fast! explains exactly what happened to my concrete bench project.
Do you think you could go farther on this topic and talk about de-icers that do the most damage and which do least to the concrete? I've read some studies that magnesium chloride is the worst and rock salt is actually best. I'm doing a bit of an experiment on my own this winter, I've taken some extra concrete beams I've made this season of different mixes and air contents and kept them, and I've put rock salt on one side and magnesium chloride on the other to compare them. I even managed to make one of non air entrained concrete at the ACI recertification class. We got our first snow on Monday, so first application has been put on!
Good content and you are a charismatic speaker - I would recommend framing yourself so your hands are in view at all times so they are not popping in and out of frame. Seems better to leave the background in (totally fine to shoot in your office - you are a professor) than to have software remove the background, which leaves a weird line around yourself. I would also leave the music out - informational youtube videos typically don't have music. The ones that have music are the ones where a guy is showing off a technique and only talking intermittently.
Hello Tyler, thank you for a lot of effort you put into all of this! I am kinda confused with different advice in different videos. As fas as I got, bleed water is helpful to avoid plastic shrinkage. But here we see that water on the top leads to formation of concrete of lower strength. So what should be done? Bleed water should be striken off but only after several hours after placement?
Dear Tyler Ley, thank you so much for your informative video. I would like to ask the reference for the relationship between %air and scaled mass at 2:49? could you please share the related paper by name? Thank you so much!
Can this situation happen with natural freeze-thaw cycles or does salt need to be present? The video is unclear on this point. Within a week of winter, my patio was poured. Five days after the pour we started to have very cold and freezing weather at night. During the day the weather was warm enough for thaw. There were a few days of rain during this time and a dusting oi snow on the 19th day after the pour. Curing temperature was poor. The concrete was left unprotected. No salt was needed. After 19 days we had scaling. It possibly started sooner but was noticeable after the snow especially in areas where the snow was left standing instead of cleared.

I never thought there was this much to know about concrete before i started watching these videos
Thanks so much for watching!!!

Tyler, I cant stop watching your concrete videos, you are awsome! Keep it going, Im learning so much.
Thank you for that information. Very helpful

"You don't want to finish too early." Said with a perfectly straight face.

How does the steel create the lower density surface, draw up or possibly trap bleed water? Your videos are awesome!
Salt as de-icing is a curse even for tarmac and other surfaces as well. Use sand or even wood ash to fight the slippery conditions during winter.
Thanks for another great video Tyler!!
Any chance you would be able to do a d-cracking tutorial video in the future?

I have a background that I want to use in the future. You may have given me the push to try it sooner. Thanks!
so how do you air into concrete? (40 years in construction and never even come across this)
Thanks dr tyler !!! Veeeery informative video and solutions to everyday practise habits 👏👍
Thanks Hamza!!!

Great video, Tyler! We are producing incredibly dense concrete, with no air, and it's impermeable and resists Muriatic acid! Go MEGASLAB™!
Thanks for the message. I think this is a cool idea. It would be cool to learn details about how you are doing this.
Sounds similar to Ductal. High SF content?
Dear Tyler Ley, thank you so much for your informative video. I would like to ask the reference for the relationship between %air and scaled mass at 2:49? could you please share the related paper by name? Thank you so much!
Great information sir!!
Thank you Kiran! Talk with you soon.
@@TylerLey Sure Sir..
How do you repair scaling from over worked concrete well finishing
I am living on a sea side area.. and we don’t have the winter issue but still got the scaling problem...is it because we close to the sea?

Dear Tyler Ley;
Please, provide me some references (name textbooks and editions) so that for improving my materials.
Thanks 🙏
New pad has scale during day 2 of wet curing
Did it freeze?
If not then the concrete may have been over finished.
Is sanding is better than salting ?
Yes but sand is only good to a certain temperature and then you need salts.
Love your content, but the background music has got to go.
Found it very hard to stay focused with the background music
I didn't even notice that it were there until this comment.
A whip crack as your sound effect?? Good information in this video, but that’s an odd choice to emphasize the cracking of concrete.
Just trying to to keep your attention.
@@TylerLey Fair enough :)
@@TylerLey defiantly entertaining too.
