Everyone's favorite 😅

❤

ADOT(AZ) has a pretty up to date set of instruction videos

thank you mister i just registered for the testing at the las vegas chapter !

Thank you for the video!!! I just registered!

it appears your videos are out of date 😭 im still watching this before i test down here in albuquerque!

Thanks from Thailand

Only six likes, Wow, love the lack of competition!

We don’t want to watch you talk

2:30 is this correct?

Thanks

I laughed so hard when he dropped the fabricated cylinder 😂 love the content 👍

I think your information is incorrect in your initial information in respects to consolidation. Although at 4:01 the reference to ASTM C192 is correct C192 does not give us a range for consolidation per lift it would be a flat 30 or 40 rods depending on the size of the mold. There should also be a range of 10-15 taps with a mallet as noted in C192. Although the video did help understand the test method in general. I thank you for many clarifications.

Excellent video for beginners to learn about it. Very well explain and professional. Thanks.

You very great man...I like all technical jobs part of Lab,,,all the way from Namibian

Question, you said do not take sample from the first 10 % or last 90% of the batch. Can you explain what you mean by this? That equals 100% so when do you collect sample?

Thank you sir I take my test tomorrow

That's a useful video 7:00

Could you possibly inform me what value should be substituted if the gauge length is not 250mm (10 in.)?

I have a doubt we should collect samples after 10% for example if we have rotating drum mixer 10m³ of total volume we could not use 1st 1m³. This 1m³ we have to dump on a receptacle or pour into a structur?

The newest ACI Field Testing Technician Grade 1 book (CP-1 40th edition printed in January 2023) shows what you call the "open top mixer" as a 'continuous mixer truck." I'm wondering where the discrepancy is. Our company owns a few and we call them "Zimmers."

this test consuming more time

Will this help if I’m testing in CA?

Thanks for making C172 very easy and simple, Appreciate your efforts.

Thank you 😊

nice work

Hello, i'am a student in mercu buana university. I'am from civil engineering. Exs. I need to the name of material cappingan of concrete thank's

Thanks

thanks for sharing

🙌🏼

Thank you for this information!

Please what is the height of the retainer cup? Thank you

You say samples shouldn't be taken from the first 10% or the last 90% of the batch... don't those, combined, equal the entire batch?

What is the Min/Max for freshly mixed hydraulic concrete? Or what is the ideal concrete temperature range? I've seen difference answers I'm studying ACI and ASTM's I am a QC inspector at a pre-cast facility in Texas

Thanks for sharing.

The CRMCA provides the most accurate and relevant to ACI and ASTM standards. I found it very helpful coming from a pre-cast facility based in DFW, Tx. Watch these procedures in preparation for the ACI exam, or for general education and improvement on your current procedures.

Good job

Thanks for sharing.

Excellent very educative and informative, Thanks.

Thanks for sharing.

Hi Are before sampling the contentious mixture should be mix or not if yes so how much time to give for mixing?

Thanks
