SOUNDNESS TEST OF CEMENT BY LE - CHATELIER METHOD
Vložit
- čas přidán 25. 08. 2024
- A cement is said to be unsound if the hydration of a hardened paste of it is eventually accompanied by excessive expansion, causing cracking and reduction in strength.
Accelerated hydration procedures are used routinely in cement production to check that it does not possess this property. The simple apparatus devised by Le Chatelier is used to indicate the expansion of a paste.Here we will discuss about the practical of soundness test of cement
Thank you very much sir
Your these efforts helps lots of student like me.
This video is made by best ways.
Without wasting time.
Best video on youtube so far.
So nice of you
I couldn't understand your language but thanks to the subtitles. Maybe next time you create a tutorial. can you please make it in the English language. Btw thanks a lot for your effort It's a really big help.
very clearly explained...thank u sir..
You are welcome
Ty for accepting my topic...
Keep watching
Your way of explaining is excellent sir😊❤❤❤
Keep watching
sir you are great performed the soundness test
Thank you
Very good 🌹❤️🌷💚👍thanks from kirkuk city irak
Kerkük'ten güzel selamlar
So nice of you
Ese hi karte रहिए sir ji.. Please sir engineering ke sb test sikha dijiye
Keep watching
Sir,the formula will be L2-L1,as In this case L1>L2 & value will comes to be negative it means there is shrinkage of cement.
Yes, Change the formula
Sir should we test it again after coming negative value reason of Shrinkage of cement
You are great
Keep watching
Great sir.. salute
Thank you so much sir 😊
Thank you sir ❤❤❤👍
Sir in video L2 is smaller than L1 , then how it will be accounted for expansion. In my opinion data sheet should be rectified in accordance with IS 4031 part3
that's true Chandrasekhar i agree with you, is it correct to say the cement shrunk by 1.9 mm? otherwise good video keep it up!
Strongly agree with u brothers
It should not be decreasing practically
Good question
Exactly .why is l2 less than l1? It is wrong then.heating causes expansion not shrunkage.otherwise explanation is gud
Thanks a lot ❤️
thank you so much sir❤️
Sir its expansion is more than 10mm so it means it is unsound?
Good work Thanks
Explained well but the formula and L1, L2 measurements were wrong...
Very nice information sir
So nice of you
Very helpful video
Glad you think so!
Thank you sir..
use thread for covering le chatiler mould
thanks for giving suggestion regarding this test
Tell the numbers in English (like.. 100 gm - hundred grams)
This will help and to reach other languages
Tq sir 😊 for the information
Very good sir
Keep watching
Thank you sir
Thank you so much sir👍🏻😊
So nice of you
Sir ,How the expansion decreased after boiling in the calculation?? Probably something wrong in this experiment..
Clear probably the cement shrink after boiling.
Yes
Superb
Thanks 🤗
Very well sir
Keep watching
Sir now this given cement is said to be what type of cement according to this result ?
Refer to IS 4031 part 3
Thank u sir🙏
Very good testing as per IS 4031 part -3 )1988
0.78P sir ji
Sir boil hone ke bad expand hona chahiye sample ko. Yaha pr boiled hone ke bad expansion km ho gya h.
This is generally wrong concept.
General people think so.
Ho sakta h. Thanx for reply
Two reading li jati hai ak normal(27°c+-2°c) temp. at 90%humidity per X1 or ak after boiling water than normal temperature reading X2
X2-X1 not greatthan 10mm for OPC
Yo that was nice
Why cement paste is kept submerged under water during the test ?
because of setting of the cement.
Sir water kitne use korega o bhi Nehi samas ta
Sir cement to shrink ho gya 2nd reading m
May be
Sir kithna time laghthahai this test ko
Please see full video with interest.
Sir L1-L2 negative Aya tho Kay ye contraction hoga Kay
What reason behind it sir why after put in hot water Gap is decrease pls sir
Sometimes it may happen
@@HIGHWAYGUIDE it means shrinking ?
L1 aur L2 thik nhi h sir
Blain air permeability methord pr vidio bnaye details me
Already posted long back
Sir concrete aiv limit with reference ...bta do
Other than wearing course it is maximum 45%•
Super sir g
Keep watching
Sir consistency mai jo water use kara uska .78%
0.78 times
Expand hona chahiye Tha but yeh to shrink ho gya
Thanks sir...
Welcome
Thank you sir
Sir what is the conclusion of it
So nice of you
