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
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%.
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
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😀😀😀

Aggregate Impact value will be less

MashaAllah JazakAllah
sampling is done in wrong way.Can we sample from single place?
thankyou soo much sir.
Sir sample oven dry ku karna hai ? Purpose?
Excellent 🙏
Is it recommended value what have you shown in the video (7.07%) ???
@@MayurPatel-uv4fm no
Very nices videos sir
Thanks for appreciation.
1/2 inch passing and 3/8 retained?
nice video sir
Well explained
Thank you
Thank you so much sir
Very helpfull sir... Thanks a lot.... But range bta dijie value ka

Thanks sir ji 🙏
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
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.

Sir plz tell imapact value of aggregate higher percentage better or lower?
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?
Extra legend watch this video only before 30min of external 😀
sir agar partical size 40mm hai to kaise karte hai aiv
Good sir
Then pass by 8 no sieve, sir please clear the confusion.
Apko test ke sath details mai limit batana chahiye road mai kitna lete hai Building mai kitna lete hai bridge, railway, tunnel, dam etc.

Thank you very much
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
Love you Sir.
Good explain
Keep watching
Sir AIV apparatus ki height ka calibration cup m agg dal kr krege Ya Fir empty cup se
After putting aggregate
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
Sir ,what is permissible limit of percentage beyond which test must be repeated?
Other than wearing course , it is 45%.
But sir....please let me know , what should be value of AIV .pls
Kitni hone tk aggregate achha hota hai?
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
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
Just amazing
👍👍👍
Thank you 😊

Tnq sir
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 ..

How much Aggregate impact value...?
Sir ham log 12.5 mm passing our 10 mm ratained hi kyun lete hai ...??
This is the Vidal provision.
Veri nice sir
Sir impact value pass h ya fail y kese pata chalega
For normal concrete work it is 45 as per IS 383 - 2016
