Percentage expansion by autoclave method is calculated taking into consideration the effective gauge length of specimen. Laboratory measures the effective gauge lengths of specimen before and after autoclaving using length comparator and a reference bar.
Effective gauge length is the inner distance between the both studd inserted in the specimen which can be measured with the help of Certified Reference Bar and calibrated length comparator.
Thank you so much respected sir
The calculation supposed to be (L2-L1)/L1*100 not (L1-L2)/L1*100 otherwise the answer would be negative.
Hello sir your video is really helpful.. and please tell me this autoclave test is done by daily basis or weekly once.. as per rule of BIS..
Each week of cement
Please refer to IS 3535 in this regard which also specifies the requirements for process / quality control purpose.

Thank you very much for very good suggestion
Sir water content aap ne normal consistency ka liya ie. 28%
But for soundness test isn't should be 0.78 p% by weight
Sir. Please make a video on coarse and fine aggregate of soundness test. With caalculation. 🙏🙏🙏
Very helpful video
Good testing good video
Namskar sir, mainne abhi as a Jen Pwd main join kiya hai mujhe cc roads k types aur layer ki janakari bataye
Effective length se calculate kese karte h

Water Consistancy ka 100%lena h ya. 78%
100% of consistency water
@@ussinha643 bhai video ek baar or dekh lo
Sir QC test ka video post kijiye
My all videos are related to QC
.78*28% *500 hoga sir water content
