Dear Sir I beg your pardon When we check free fall height of hammer 380+_ 5 mm that time mould should be filled with aggregate and top of the aggregate surface height should be measured
Thank you sir. Very nice video, but sir if the height of free fall of the hammer is less than the prescribed value, what will be the effect on test result ?
@@HIGHWAYGUIDE absolutely right...qki jitna paas se hammer use karenge...agg. utna hi kam broke hoga ...jisse 2.36 sieve passing fraction ki value kam aaygi...to jaahir si baat hai...impact value bhi km aaygi
Impact load means suddenly apply load And crushing strength means gredualy apply load. Impact value test use for highway construction which have impact load from wheels. And crushing value is useful in foundation column and other structures
As per IS 383 - 2016 , There is only one limit for AIV for all concrete work in India 45 % except wearing course i.e runaway , spillway , road pavement , tunnel lining carrying water 30%.

AIV test dekhne ke baad mujhe lag rha hai...impact value kam honi chahiye...kya mai sahi hu...pls bataye... aur ha tolerance bata dijiye pls....for good concrete
sr ye dono cylinder k dia alag alag hai small wale ka 75mm or jisme test perform karte hai uska 102 mm yadi ham testing cylinder dia.102 mm usme direct sample ko 3 layer me fill kare 25 blows k sath ,,fir test perform kare ,,,,ye thik rahega ya ni ..
Practically there will be no difference , can do but how you take weight and it will be difficult to keep fall 380+/- 5 mm.As per contract in your project or any project we had to follow Indian standard.
You have weigh dry sample weight 357.70 gram including steel cup and haven't deduct cup weight for net weight of material.so material weight will increase and impact value comes less.please explain
Thanks a lot sir
I have missed my transportation lab class but after watching this i am prepare for viva
Thanks a lot
All the best
Legends watch 1 hour before practical exams😀😀😀
❤️
Same condition 😂😂😂
🫡
You are right.. mere practical hone wala h after one hour 🤦😅😅
Ultra legend see on site during job before performing 🙂
awesome sir.... you have explained clearly at every step. This is a part of our project.
Thanks for this Informative videos, keep uploading more testing videos related to civil engineering.
Thank you, I will
Few persons like u, make civil engineering study interesting.
Thank u ❤️
Nice video sir clearly samaj me aa gaya tnq sir
Thank you
Thankyou sir uploading video
Keep watching
Thank u Sir uploading
Good knowledge for civil & special for Quality.
Thanku sir for this Beneficial Tests. This is really a best way to learn best
Keep watching
Bohot hi badhiya samjhaya sir dhanyawad 🤝
You guys are awesome. Waiting for more field and lab tests. 🥰
Keep on watching
Pura process mind me aa gaya sir thanku ❤️❤️
Thank you
Awesome video sir . Plzz sir aur video banaiye n
Very nice sir ❤
Very helpful. Thanks sir
thank u so much we need more videos like this its so helpful for my exam tom u hav explained everything in detail u r a life saviour 🙌🙌🙌🙌🙌🙌
Very good video for civil engineering students I am also civil Eng student. Thanks sir 🙏🙏
Keep on watching and share to your class mates also for their benefits.
Koti koti prnam sir g bhut achha samcha mai aya hai
Keep on watching my channel and share to your friends also.
Thank you for giving us a video..
It's my pleasure
Tqsm Sir 💙 You Have Explained Clearly 💥 AIV Testing
Very clear and visual practical
Thanks for the awesome video.

So nice of you
Very gud explanation
sir good video but you don't minstion minimum % maximum
for example ; result is minmum 5% to 11%
For other than wearing course , it is 45%.
Good and must question
Very well explained
Thanks sir.

Aggregate Impact value will be less

Thank you sir for giving a video
So nice of you
Good
Sir what's difference between aggregate crush value and impact value.
If anybody knows pls reply
U don't need to do LAV if u do AIV. They are pretty much same. Nowadays LAV is obsolete.
Impact load means suddenly apply load
And crushing strength means gredualy apply load.
Impact value test use for highway construction which have impact load from wheels.
And crushing value is useful in foundation column and other structures
@@A____k thank you bhai
thankyou soo much sir.
Thanks ☺️ for this video
Thank you so much sir
MashaAllah JazakAllah
Excellent 🙏
Thank you Sir ,
Please explained over tests.
Very nice demonstration with sound explanation......👏👏👍👍💐
Keep on watching
.
Apko test ke sath details mai limit batana chahiye road mai kitna lete hai Building mai kitna lete hai bridge, railway, tunnel, dam etc.

Wow Exeliant sir 5*

I understand the how to do aggregate impact test clearly.. But what is use of that aggregate impact value...?
The main aim of this test is To determine the impact value of the aggregates used in pavement construction(Road
Very clear video
Sir will the size of the aggregate taken for the sample remain same for Water bound macadam...passing 12.5 and retain on 10mm?
Yes
Thank you sir 👍👍
Most welcome
Very good
very well explained

👍👍👍
Very nice video sir
Keep on watching
nice video sir
Very nices videos sir
Thanks for appreciation.
Good explanation
Keep watching
Sir ,what is permissible limit of percentage beyond which test must be repeated?
Other than wearing course , it is 45%.
Love you Sir.
Before one night of exam like
Very helpfull sir... Thanks a lot.... But range bta dijie value ka
As per IS 383 - 2016 , There is only one limit for AIV for all concrete work in India 45 % except wearing course i.e runaway , spillway , road pavement , tunnel lining carrying water 30%.
Awesome❤️
Then pass by 8 no sieve, sir please clear the confusion.
Sir plz tell imapact value of aggregate higher percentage better or lower?
sampling is done in wrong way.Can we sample from single place?
AIV test dekhne ke baad mujhe lag rha hai...impact value kam honi chahiye...kya mai sahi hu...pls bataye...
aur ha tolerance bata dijiye pls....for good concrete
Sir g can explain how much limitations of test results
As per IS 383 for general concreting it is max 45 % but for wearing course it is restricted to max 30 %.
very nice vedio sir
Thank you for your valuable comment.
@@HIGHWAYGUIDE in 10 mm aggregate sometimes we will not get any retained on 10 mm sieve in this case what we can do?
sr ye dono cylinder k dia alag alag hai
small wale ka 75mm or jisme test perform karte hai uska 102 mm
yadi ham testing cylinder dia.102 mm usme direct sample ko 3 layer me fill kare 25 blows k sath ,,fir test perform kare ,,,,ye thik rahega ya ni ..

Sir AIV apparatus ki height ka calibration cup m agg dal kr krege Ya Fir empty cup se
After putting aggregate
Still students do civil Engineering
Good sir
1/2 inch passing and 3/8 retained?
Mja aa gya sir
Sir please aap you tube per video kis category me upload karte ho please sir bata dijiye me bhi apki trah hi video Upload krna chahata hu please sir
Well explained
Thank you

Before writing comments , please see video carefully .
I have tared before taking sample weight.
@@HIGHWAYGUIDE sahi kaha apne...is bhai ne theek se nhi dekha...apne us cylindrical measure cup ka wait zero kr diya tha
Sr mera 1 question hai jo blows de rhe 15 times uska weight kitna hoga
Sir I have one doubt why didn't not subtract bowl weight from total weight
Please see I had tared.
Thank you sir 🙏
Most welcome
But sir....please let me know , what should be value of AIV .pls
Thank 🙏❤ u sir
Sir sample oven dry ku karna hai ? Purpose?
Thank you 😊
You're welcome 😊
Just amazing
Tq so mach sir
Welcome
Thanks sir far this
