1. Oven dry aggregate passing 12.5mm IS sieve and retained on 10mm IS sieve are selected for the test. 2. The cylindrical measure is filled by the sample aggregates in three layers approximately equal depth and each layer being tamped 25 times by the rounded end of the tamping rod. 3. After tamping the third layer, the top surface is leveled using the tamping rod as straight edge. The test sample thus takes weight as W1 gms. 4. The cup of the test apparatus is placed in position on the base plate, the test sample is transferred into the cylinder in single layer being tamped 25 times and the surface of the aggregate is leveled. 5. The hammer is raised until its lower face is 38mm above the upper surface of the aggregate in the cup, and allowed to fall freely on aggregates for 15 times at an interval of one second. 6. The crushed aggregate is then removed from the cup and the whole of it is sieve on the 2.36mm IS sieve until no further significant amount passes. The fraction passing the sieve is weighed accurate to 0.1gm. and noted as W2 gm.

very informative video i appreciate it love from pakistan

[@SumitRaj-oq1lq]

Sir your video is very good. I learn aggregate crushing , impact value. But i cant find the loss angles abrasion value of coarse aggregate. Plzz suggest

[@venkatamanigopal005]

Sumit raj s nice videos sir

[@anandhusathyan1141]

Love you sir, your video is very helpful sir.

[@aswin1974]

Thank u sir

[@mohdadnansiddiqui4021]

Very well explained thumbs up brother

[@thestructureengineer2573]

Best quality video sir.

[@ilyasahmed4773]

Thank you sir explained very nicely

[@prathikjsk6430]

Thank you sir such a nice explanation

[@zainullahzain5718]

Because You take the sample from practical field

[@sisindriballikurava2477]

Sir it is good but you don't mention the dimensions and hight of the 15 blow's is not mentioned hight don't rept the sir

[@ayushanbhore8145]

Thank you

This video is really helpfull....

[@mustafeyousuf3228]

Sir thanks aggregate impact value And aggregate crushed value which one the pest practical for road traffic impact

[@deviprasad6210]

Sir so good explanation upload more videos on ce lab

[@Civilophilic]

nyc vedio sir....thank you

[@aayushgupta3291]

Sir,please off the fan for more accurate weight reading

[@zainullahzain5718]

Nice

[@bishnurajwar7973]

Very nice sir

[@nasra_nasra]

What is the relationship between impact value and toughness I mean what will happen to aggregate if impact value is high or low???

[@anchal2575]

If impact value is high ....it show the weak toughness for pavement surface....it can't use in construction work!!!

[@krishnakumari4683]

Thank you sir...

Sir adhi 10mm kadu 10CM

[@manojvenkateswarlu2252]

we are giving 15 blows why should we give only 15 blows why should not give 20 blows

[@dasarisairam7652]

Why we take 10mm only

[@anchal2575]

Because 10mm is better to use in pavement surface

[@gangsta9605]

It's good
