@@nityanandasenapati4878 If you do not change the area of needle penetration of 25 mm will not be possible within 10 second . So after the increasing time when cement is going to set area of needle should be less to penetrate 25 mm within 10 second.
@@sudityabhattacharya5423 Please refer to code for initial setting we require penetration resistance 3.5 MPa means 3.5 N/ mm2 So we have apply force in Newton with particular area (mm2) of needle.
Why are we use six penetration needles of different dia at different time interval ? Why not using one single size penetration needles at different time interval just like setting time of cement ?
Sir bahut din pahle mene apse pucha tha ki sir rmc se concrete ata h &kai jagah client bolta h ki 2hr bad reject kar dunga kahi bolte h ki 3hr ke bad reject kar dunga aj sahi time h kyuki is vedio se related hi qtion h ki kya criteria h sir concrete reject karne ki timing ka please sir answar
To convert a kilogram-force measurement to a newton measurement, multiply the force by the conversion ratio. Since one kilogram-force is equal to 9.80665 newtons, you can use this simple formula to convert or simply multiply with 10. newtons = kilogram-force × 9.80665
Itna khoobsurati or itna bariki ke saath test ko samjhne ka bohot bohot dhanyawad sir........plzz aise videos or laiye ........ 👍👍
Sir, apki smjhane ka tarika sbse best h, nd apki video bhot helpfull hoti h, thanks sir for the clear all fours🙌😌❤️🙏
Sir aapki saari video ki jitni tarif ki jaaye kam hai. Means deliver the knowledge in easy way.
So nice of you
Sir aapki sabhi video bhut bhut achi h baaki sab youtuber se
Keep watching
Sir वीडियो बहुत अच्छा है
Sir jab bhi mujhe kisi test m problem hoti hai ...me Aapke TH-cam k video Dekh k solutions dhund leta Hu
Thank you very much ⭐💜🙏
Thank you so much sir very less videos are there of this test , thank you for making n explaining it nicely
Thank you very much
Sir exact pressure kaise pta chalega koi dusra. Banda krega to wo alag pressure se dabayega to jyada force aa skta hai
Thank you sr mje is video ki zrvat thi aur apke naye channel ko subscribe kr liya hu
Thank you very much , I know you , in spite of my more than 30000 subscriber. You are my favorite one.

Very very very well explained👍
Thanks for liking
Good video bhut Dino bad video bnaya sir
Now I am available , no problem sorry for that . Please subscribe my another channel which is being run by my wife 'Vandana Khana Khazana
Good explanation.... Thank you so much sir
So nice of you
Good Effort...Thank you.
Sir Admixture dose kitna le sakte h as per standards. And refer relevant standard.
As per your design
@@HIGHWAYGUIDE maximum dose for PC base Admixture
Sir pls can you explain effective CBR for flexible payment.
IRC 37 me hai but mujhe samjh nhi aaya
OK will upload a video
sir , u change the bearing area why , please explain it clearly initial set ing time ka penetration.

Sir,is there any limited concrete IST & FST as per standards?
No
Maximum FST & Minimum IST for Durable concrete?
Why you take unit of pressure in Newton?

Ap beech beech me temperature&humidity show kar raho ho usme ambient temperature 27.5°c h ok but ambient humidity ka kya criteria h sir
I am showing the time .

Please use single needle and do the practical.
Thank you sir right information
Excellent 🎉
When and how do you know which plunger to use
Please read IS 1199 -P7 to understand the concept
Good Explanation.
Glad you liked it
Lots of thanks
بہت بہت شکریہ
Sir very nicely explained about initial and final setting time in concrete
I have a doubt how you are selecting the dia of needle for different times?
Please , do practical .
Outstanding

Concrete should be poured before initial setting time.
@@HIGHWAYGUIDE thanks sir
Very helpful video
Glad to hear that
Sir es equipment ka name kya hai
Penetration resistance apparatus having a pressure gauge of capacity 700 to 900 N. Removable needles of 645, 323, 161, 65, 32 & 16 mm2.
Bahut aachi video hai
Thank you
Sir initial setting time kaise aaya pta nhi chala please answer
Please see the full video once again with interest.
Great 👍
Sir shotcrete ka setting time kaise check karege
Same procedure
Sir this is method for concrete setting time test only but I want to test on site
Because sir, we use accelerator in shotcrete ( Concrete), whose final setting time is 12 minutes.
Reapected Sir, What is the Apparatus Name ?
Concrete Penetrometer
water kitna kg dala sir
Request you to please see full video
Sir iska limit Kitna hota hai please btao
There is no code available for limit

Nice information sir
So nice of you
Thanks.
You're welcome
sir please explain calculation

very nice sir

Thank you sir
Thank's
Actually I have done it in the lab but my confusion is how to decide which needle size to use it when since you are changing it.
After so many test I have decided the needle .Please follow my video.
🙏
Good
So nice
1kg =9.81newton
16*9.81=156.96n hoga
Mere khyal se
Thanks sir
