this is really nice , thanks
i think beams also minimized......
pl show the procedure of stretching after initial setting of slab,
Surely Mukesh thanks for ur revert
Nice information
Thanks for your valuable comment
very useful
Yes its very important topic.
Sir, slab Jb set ho jata initial setting Time pr uske baad hm tendens ko tite karte h tb slab m crack aane ke change rhte h kya
Mashallah
👍👍
Nice
Thanks
Very nice information sir
But my question is what we do if casting as well as live end of tendon Bursted ?
Why should provide bursting rings at dead end or Bulbing side ???
Hi, can u pls elaborate ur question.
Thanks for watching
Hi, Great video & efforts but could you kindly enlighten us with few points as i m interested in using PT slab for a huge basement but ehile doung some research i got to learn that the LIFE SPAN OF PT SLAB IS JUST 15-20 YEARS and are failing at a much higher rate.
and it requires highly specialized labour & machinery.
The design calculations are more complex
Structural elements are susceptible to corrosion.
The cost of this construction system is higher, due to the fact that the anchors are unrecoverable & that the reinforcement bars need to be inserted correctly inside the conduits
Also Extreme attention is required during the installation of the reinforcement anchors and their coating.
However, the prestressed construction system when using post-tensioned concrete is significantly more complicated than using standard reinforced concrete, so usually the profit by gained by saving material costs tends to be minimized by the requirement of using specialized equipment.
Post tension slabs are strong because of the cables inside of them. *When one or more of those cables fails* due to damage, they aren't as strong as they once were. This can cause slab or structure failure that can cost an obscene amount of money to repair, and it can be dangerous
👍
Thanks for your inputs … so if it’s a personal residence of say 500-1000 Sq mtr then no one will use it for personal use if this is the scenario??
Hi sir, thanks for practical demonstration. Do we use pt slab in non basement areas also like in seiling of multistory building?
No, we use pt slab for central basement, we can’t use for tower slab / buildings slab
@@BasicsofCivilEngineering but it can be used for upper floor slabs as well like podium slabs of malls in a MUD for example- jamshedpur riviera
What is the mode of measurement for PT tendons?
Information is good but incomplete,also should show tendon how it tight and after tight , pressure grouting also require ,why and where burst reinforcement added,all this you can be add so it would be perfact vidio but whatever information explained is also good thanks
Nice comment Upendra , thanks
Sir Residential bunglow mai use kar sakte hain ya traditional slab better option hai (3500 Sqft Slab Area) maximum room size 27 x 22 feet hai other room size 20 x 16 feet hai.(2 BHK hai)
Chhote area k kiye ye cost saving ni h.
Bungalow me ap proper slab dallo
Koi issue ni h
is this type of technique is possible in organic planning? where we have curve shaped planning like malls?
Didn’t understand, pls elaborate more
@@BasicsofCivilEngineering I meant that in case of organic planning where the forms are parametric, and column grids are also not in proper 90 degrees
Conduit ke ander tendons hai aur uske baad bhi jo steel dikh rha hai wo tendon hai ya normal tmt steel?
sir i would like to know the name of material used to wrap the tendons during use in casting of slab.
Pls watch this video.

This vll help u a lot

Sir; It is very useful video. Only thing that in case of sunken slabs for accounting nahani traps and water plus drainage pipes, how sunk would be provided? Kindly post guidance. Tnx
This we are providing in basement slab & podium slab where there are no sunken.
Sunken to provided in raft /footing level
Thanks for your valuable comment
Sir What should be actual cost of whole construction per square foot slab area
Sir that means average cost for per square ft is around 35 rupess. It is with material or only labour cost.
Yiu need to know per sq.ft. cost of pt slab ?
Kya mujhe pt slab ka koe jaipur me kam karne wala mil sakta hae pls reply
I'm constructed 5200 sq/feet basement
What is the best option for it flat slab or pt slab or normal slab
Pls go for normal slab, for house normal slabs are preferred
Sir is it possible for all slabs for multi storey bldg.pt.
Generally it is preferred for non tower/basement slab .
Multi storey me ye use ni hota
Pt slab tightening edge, how it will be looks like, please share details.
Maine 1 video aur upload kiya h regarding pt slab , do visit that vidoe, this vll help u out
Thank you sir.. This is my first experience with pt slab on my site ..very good information
Thanks for your comment dear

Which steel(TMT) is use in P.T. slab mat ?
Minimum grade fe500 / fe550 primary steel .
Please mention technically, like how much initial stress, how much final stress, mechanical instruments name all things, otherwise it's llike very general knowledge
Can we used for residential
Yes, it can be used
Sir totally which slap is cheaper pt or normal
Pt slab is cheaper
Sir after 7 day k baad he tendon stretch kue krte hai after casting next day kue nhi strech krte hai sir....
Because within 7 days rcc attain 70% of its strength .
Sir this is flat slab do not provide beam??
PT slabs sathi lagnare row material aamchya Kade bhetel
Not able to unable your question, pls ask again
Thanks
If PT slab is so cost effective and does provide more strength, why can't we use it on all floors of the building except for the basement slab?
So Rishank, if you refer both the video (Part 1 & Part 2) on PT slab , you will come know that the procedure of PT slab is quite long & it suitable for Large slab (Where heavy Reinforcement is used & having good sizes beams). for normal slab, we have less area, low area pour of casting, beams sizes are less & most importantly we have to maintain our speed of construction .
Hope this is clear to you !
Thanks for asking such as good question !
@@BasicsofCivilEngineering thank you so much
I would also like to add that PT slab is not suitable for commercial buildings as you cannot puncture a PT slab suppose you want to connect two floors and provide staircase in between ( for some retail brand ) that's not possible if it's a PT slab
Sir kya PT slab ko pinchar kr skte hai
Yes, pinchar kar sakte h ,
Pt slab thk 27 cm ka rakhte the dubai me hum log. Aap kitna rkhate ho?
It may varies from 230mm to 300mm
Dear sir..,
It's useful for load bearing structure or not??.
Yes it is.
Thanks for ur comment Sukh
It is also called beam less slab.
Sir it is flat slab and do not provide beam ??
Yes, beams are not provided in this, thats y ye sasti padti h , steel & rmc kam lagta h
Thank u very much for solvin my query
@@BasicsofCivilEngineering sir How much rate 1 S.F.T
@@civilknowledge11 pls ask again
Gadar pt selef ka video aflod karo
Sir PT slab ka drowning se lekar work pura malum hai sir saudi me kam bhi kiya hu par india kam nahi milta visa bhi nahi milta sir
Ri8 now india is going through Pandemic dur to Covid 19 , to kaam bhuat jada ache se chal ni ra h,
Wait for sometime market dherre sherre open ho ra h
After 7 days strength of cube testing then it will be stressing
Yes absolutely, after 7 days rmc gets 67% of its strength
Podium slab kia hoti hay
Podium slab 1 tarah se non tower area ki slab hoti h
Non tower kia hota hay..??
Project is divided into 2 parts
1. Tower Area - yahan par tower construct kiye jate h.
2. Non Tower Area- yahan par tower ni hote, landscape, club , footpath etc banate h. Use non tower area kahte h
This work is with material or without material
With material
@@BasicsofCivilEngineering you told the cost of work is 88 lakhs without gst and with material and you told 350000 sft work for 88 lakhs means rs 25 per sft
@@BasicsofCivilEngineering labours are charging more than rs 25 per sft
after how many days ,the tendons are tensioned??pls specify
After 27 days. Because after 28 days RMC gets its maximum strength
Thanks for your valuable comment
@@BasicsofCivilEngineering 1) but sir in the first video at 9:30 you mentioned that the contractor will tighten the tendons after 8-10 hours of casting i.e. after its initial setting time
2) in the second video you have mentioned "stretching done after 7 days of casting" i.e. tensioning of the tendons
3) and here in the comments you mentioned it is tensioned after 27 days
sir, i am unable to get the data for this ..would be rally hepfull if u specify the above.??
@@zimi7616 after 7 days
Here in malaysia. We will start stressing after 3 days. After the concrete cube tested and achieved the required strength. G30.
1. Per Sq Ft Cost PT including tensioning contractor - end cost. ?
2. Per Sq Ft Cost normal slab?
3. Mostly without PT Slab - normal slab- thickness is 150mm
PT slab thickness kitna kam hota hai?
4. PT slab kya 500-1000 gaz ke project mein 5 floors mein sab slabs mein use kar saktey hain?
5. Kam thickness ki slab mein chalne ki dhamak - neechey ke floor mein ayegi kya?
Aap ka video is very good and informative
Thank you
Mera ko malum ha
Good
What is Per sqrft rate with material?
Material rate is about Rs 30 - Rs 35 per sq.ft
PT slab vendor ?
U want to award a contract to any vendor ??
PleaseGiveDetail
Costing is not clear
Approx Rs 45 per sq.ft.
If you have any specific issues regarding cost, pls ask 😃
Why isn't this in English? What market the video on here like it's in English and then have it in a foreign language?
Edit - all the comments here are in English and now I am super confused haha. This is weird.
Hi, this videos is for all site supervisor (non Technical) , formans, & engineers.
Everyone is not comfortable woth English that y i used Hindi language to make them people more understandable.
Hope u understand
Thanks for comment
@@BasicsofCivilEngineering thanks for the response. It's still bizarre to me that everything about this videos labeling, the comments, literally everything indicates this being an English language video and then it's narrated in Hindi. I'm not mad or anything, just wanted to learn about post tensioning slab since I read it could have been a part of why the building in Miami collapsed.
Koi video bahut interest hai PT slab ka Upar rahata hai na uska naam rakhne ka
Hi, i am not able to understand your question , can u pls come again.
Where are the beams
Only colomn
There is no concept of beams in pt slab , it help to avoid beams
Oo i got it then the cement consumption is more than normal slab the is is expensive
@@Shreyas_-cj5de PT slab reduces the Steel consumption in the Slab, Grade of RMC would be same , we are using M30 grade of Concrete with same cement ratio.
PT slab saves cost.
Bhai kmse km technically bataya hota

If you are not intending to use English to explain, don't put the title in English, otherwise provide subtitles
Thanks for your advice.
But my audience want in this format only. & my audience is valuable for me
@@BasicsofCivilEngineering I wanna be one of your audience, could you please put subtitles?
I really appreciate your effort in making this video, if you want more followers, use additional communication channel like English subtitles 😊
Thanks
