@@Kei1youtube hello there, well my samples was cured for 28 days, In case of avoiding any abnormalities, I suggest to cure it at least for 7 days.

@@sks126jntu it might be a little hard for you to perform it, for instance you must have bigger pot to boil the water with specimens inside, other way, sure, go for it.

As far as I now, if you want to conduct this test on reinforced concrete, it will not gave you an accurate answer, cause the steel has much higher pulse velocity comapred to concrete, therefore if you want to use it, try to avoid the steel during measurement, another issue is, at the end, this will gave you the cracks existence or any abnormal inside the concrete.

Hello, I made an instance at the end of the video, pls go and check it. By the way, there is no apparent mass, there is apparent density wich I wrote the formula, and I describe every elements in regard at the top ot table.

Thank you, I am happy that it been helpful. After the boiling step I just let the samples to cool off and then measured the mass inside the water, I didn't put it again into water for a moment. I must add that, this is according to the ASTM standard and based on Archimedes principle.

yes, you are right, we must cover the bowl during 90 sec waiting.

Thank you for your comment, I'm happy I could help.

you are so precious to me my friend.
