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
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
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
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
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%.
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.

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.
Few persons like u, make civil engineering study interesting.
Thank u ❤️
Thanks for this Informative videos, keep uploading more testing videos related to civil engineering.
Thank you, I will
Nice video sir clearly samaj me aa gaya tnq sir
Thank you
Thanku sir for this Beneficial Tests. This is really a best way to learn best

Tnq sir je
Very helpful video.
Very helpful. Thanks sir
Sr mera 1 question hai jo blows de rhe 15 times uska weight kitna hoga
Nice Explain & very informative video 👌
Thanks a lot
Tq so much sir you have clearly A.I.V Testing 🙏🙏
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 ?
Aggregate Impact value will be less

Sir sample oven dry ku karna hai ? Purpose?
Very clear and visual practical
Very nice sir ❤
GOOD 👍❤
Is it recommended value what have you shown in the video (7.07%) ???
@@MayurPatel-uv4fm no
Good jobb. Thanks for uploading this video
Very nice demonstration with sound explanation......👏👏👍👍💐

.
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
Sir AIV apparatus ki height ka calibration cup m agg dal kr krege Ya Fir empty cup se
After putting aggregate
Very well explained sir
Keep watching
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
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
sampling is done in wrong way.Can we sample from single place?
Sir I have one doubt why didn't not subtract bowl weight from total weight
Please see I had tared.
Thank you Sir ,
Please explained over tests.
Before one night of exam like
Sir plz tell imapact value of aggregate higher percentage better or lower?
Very gud explanation
sir agar partical size 40mm hai to kaise karte hai aiv
1/2 inch passing and 3/8 retained?
Good explanation....

So nice of you
thank you sir bilkull samazz me aagyaa 🙏
Thanks for appreciation.
Then pass by 8 no sieve, sir please clear the confusion.
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
Apko test ke sath details mai limit batana chahiye road mai kitna lete hai Building mai kitna lete hai bridge, railway, tunnel, dam etc.
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%.
Sir ,what is permissible limit of percentage beyond which test must be repeated?
Other than wearing course , it is 45%.
Thanks ☺️ for this video
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
But sir....please let me know , what should be value of AIV .pls
Thank you sir for giving a video
So nice of you
Bohat hi zabardast Sir Thank you
Kitni hone tk aggregate achha hota hai?
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.
Very well explained
Thanks sir.
Thanks for liking
Thank sir so for amazing video
Keep on watching
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
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
Sir ham log 12.5 mm passing our 10 mm ratained hi kyun lete hai ...??
This is the Vidal provision.
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 %.

MashaAllah JazakAllah
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%.
How much Aggregate impact value...?
Ultra legends watching this video before job
Aggregate kaunsi acchi ho kitne percent tak passing aggregate honi chaiye jisse aggregate acha hai ya nhi pata chale..plz reply sir
10 %, sai kam hu tu buhat zyada strong hai use kar sakty hu 40 % ke bad teek nahi hai
Thanks sir ji 🙏
Sir whenever I try to get your membership,my request got rejected while doing payment please resolve my issue
Try with VISA CARD
@@HIGHWAYGUIDE ok sir
Sir in highway how much impact value of aggregate is permissible.
For highway or concrete work ?
Thank you so much sir
Still students do civil Engineering
Bt, sir, Aggregate ki impact value less than 6% honi chahiye. Aaur aapka greater than 6% h. Is this possible..?
In which code it is written .
Hammer ka wt kitna hota he sir
Sir impact value pass h ya fail y kese pata chalega
For normal concrete work it is 45 as per IS 383 - 2016
Wow Exeliant sir 5*
Keep watching
Impact value kitni honi chahiye sir
thankyou soo much sir.
Sir limits kiya hoti h
Sir 20mm aggregate ka nahi karte kya??
We have to take 12.5 mm passing and 10 mm retaining material.
Very good
Thank 🙏❤ u sir
Kitni value aani chahiye jisse material pass hi
Aur kitne pr fail hogi
As per IS 383 , for concrete other than wearing course or normal concrete is 45% and for PQC 30 %.
For DBM 27% and for BC 24 % as MORTH 5th revision
Initialy aapne kitna sample metal liya yeh to nahi bataya , aur 63 to 45 mm metal ka A I V maloom karna ho to pehle kya karenge,
Please see video with interest.
You have to break the sample to required size ( 12.5 & 10 mm)
Sir aapne %age nikalte time bowl with aggregate ka wt. liya h jabki %age agreegate wt. Pe niklegi pl confirm
Bowl has been tared , please see the video carefully.
