Sir, after water curing concrete specimens(150mm*150mm*150mm) for 28 days, do we need to dry specimens in a oven before placing them to the machine? Otherwise, specimen is already wet and isn't it difficult to identify clearly water penetration mark.
Sir what is the standard limit for concrete pouring ( minimum to maximum) Please do reply 🙏🙏 Are February to March suitable months for construction in jammu and kashmir as the temperature here is cold ... Please please please reply sir 🙏🙏thanks
It is always better to take the average of at least 3 concrete cubes. More the number of samples considered for the test, better is the obtained result.
@@gulnurtumur2726 I believe you have 3 specimens for each mix. Is it right? If so, then you can determine the max depth for those three cubes and then you can take the average of the maximum depths. Also determine the standard deviation to show errors bars in your graph.
Normally we take maximum of 25 mm maximum depth of penetration but where it is mentioned in any Is code or reference pl share ?

Where is this test available
What is that machine's name

i think is good to dry one of test specimens compare results. should be easier, as sometimes it very difficult to tell difference.

is this same as a permeability test of concrete?
i got it, thanks
Can you give an excel file for calculations
Thank u mam
Incomplete...
how to calculate the coefficient of water permeability of concrete by DIN method?

how to prepare caoh2 solutiom
it was very helpful thank u very much.. :)
Good and incomplete kindly give us the entire procedure including results sir
How to do calculation??
either one cube is enough for the test or we need to test for 3cubes and taking an average of them?
+Vamshikrishna Krishna in any science measurment the more the better, take 10 and average for more reliable data

@@LearningCorridorBharathMS I have three samples for each sample i will take max depth then i will take their average again?

good but Incomplete ..
Would you please tell me how to calculate permeability coefficient of concrete via your test? Thank in advance.
Very informative.
Nice Explanation!!!!!! But Could we get and criteria as per Oxygen permeability Index. Like which value is acceptable and Which one is not?
