Thank you for the incredible explanation
Very Easily Understandable and Nice Animation
This is the better video for post tension slab
Excellent explanation!
This narration reminded me of Mike Tyson
no Daffy Duck
It's a great job
Wow neatly explained👍
does this include the prestressed process?
We are manufacture in China. This video is great
👍👍👍👍great job
Thanks for sharing as we now understand how this takes place.
Will be getting my House built later this year and just found out about the Post Tension Slab. I definitely will use this
If ya need a crew message me we do pt
Even if you try to buy or rent the equipment it is expensive. Also dont trust any crew as they can cause blowouts if not stressed right.
Depending on where you live it's unnecessary unless you have a helipad on top of your house then go for it
@@professionalchimp blow outs don't happen if stressed right nice try sounding like you know what your talking about... that's the last thing you would want to worry about... its all installation kid ... stressing isn't hard at all ... and it's not expensive at all its actually the opposite...
good video. Keep it up
Thanks 🌹
Thanks for shearing
wow, amazing
Nice 👍👍👍 tq very good useful information sir...
How to keep marking line(under ceiling) when painted, if you have please share info and photos, thank you very much!
This kind of slab is very practical
Safe time
Safe cost
Decrease steel
Decrease concrete
Decrease weight of the total building
Good job
thank you
Well done
What is the role of grouting in post tension method?
Nice.
Tare are relation between strength of the concrete and tension of the strain steel
Can this beam be punctured ?
This is bonded tendon, right?
Kindly share details for post tensioning grade slab for concrete flooring on ground.
You should explain drape and post tensioning in increments as the concrete hardens to the design strength...
you probably dont care but does any of you know a way to log back into an Instagram account?
I somehow lost the password. I appreciate any tricks you can offer me!
@Emanuel Creed Instablaster =)
@Jermaine Wade i really appreciate your reply. I got to the site thru google and im trying it out atm.
Looks like it's gonna take quite some time so I will reply here later with my results.
@Jermaine Wade it worked and I now got access to my account again. Im so happy!
Thanks so much you saved my account!
@Emanuel Creed you are welcome xD
They poured concrete on to OSB? Is that normal lol. I would think it would be some kind of steel decking material.
Yes that’s normal
It's normally used on occasions they do have metal decking
What is this software
How does a steel rod in tension make the concrete stronger ? Is that what it does?
When you stress the steel rod (rebar), you create a static compressive stress on every square inch of the concrete. That rebar adheres to the concrete and once you stretch the rebar, it wants to go back to its original length. So it's pulling the concrete together. This is good for the concrete when it experiences tension. For example, if you have a slab of prestress concrete and you support it on two sides, leaving the middle unsupported, and you press down on the middle, the middle is in compression and to the left and right of the center you are imposing a tension. However, because it is pretensioned, the tension that is imposed by the load has to be greater than that imposed by the rebar in order for the load to actually affect the concrete. You are effectively transferring the tension from the concrete to the steel and steel is really good in tension.
Is this common in high rises? Quite involved!
Yes. This is typical in all multi level concrete structures and even in some residential
The guy above said it well enough
give you training? on line? I am interested.
In how many days de-shuttering can be done in case of PT slab ?
After 65% to 70% stregth gain for concrete. Usually after 7 to 10 days for 3 ksi concrete
it is better to pour the columns first and then pour the rest of all. More safety.
Yes that’s how they do it 1 week before pour day
Where are working your company???
How much for rate in sft
is this band beam ??
No beams where in the video
what is the machine used to stress the cables called?
Vanguard
A stressing machine is what it's called ... or a ram and a pump
Now i get it
who can install this kind of slabs on California?
Union Ironworkers local 416
2:00 what is that spray???
Marking spray they do that to measure the cable when they do the final stress :)
It is a bot reading it LOL

the speaker has a speach impediment. why choose this person for the voice? difficult to understand.
You just read what was already on the screen and explained nothing
Weird how he speaks English 99% perfect but the sentence structure is off

😂😂😂 these comments
Poor detail
Just ruined a great informative video by ding dong music!
I observe that it is not what they advertise it to be and it does not look like it adds the advertised strength unless the tendons are straight and the pouring of concrete does not deform its straight shape.
