Hello, may I ask how to UPV Test the reinforced concrete and how to interpret them? We want to determine the crack formation.
@omiddeldar2 ай бұрын
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.

It's really a nice video. May I ask you about the purposes of the third (put the sample in the boiling water) and the fourth (put it again in the water for a moment) step here? thank you so much for your kind attention.
@omiddeldar3 ай бұрын
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.

Is it possible for me to know that the cube consists of mortar or concrete and according to any specification the mixing process took place? Can I use the mortar to which supplementary cement materials have been added according to ASTM C109 for this test?
