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
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
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, 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
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)
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
@@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
Please mention technically, like how much initial stress, how much final stress, mechanical instruments name all things, otherwise it's llike very general knowledge
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 !
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
@@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.??
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
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.
@@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.
@@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 😊
