ACI Field 1 - ASTM C173 Volumetric Air (Roller meter) - CRMCA Online Concrete Procedures (v2-2022) 

It’s crazy, I remember standing in that room for my ACI exam

Thanks for sharing this with me, I am getting ready to renew my certificate for the fourth time and I only perform this test during each exam, I usually inspect prestressed concrete and masonry and for the last three years I have been a building inspector, I do not even do any tech work.

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

Thank you sir I take my test tomorrow

Thanks for sharing.

Everyone's favorite 😅

Good job sir thanks

hello sir? Any jobs available. I can teach concrete Level 1 and most of soil level 1

this test consuming more time

We don’t want to watch you talk
