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."
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?
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?
Thanks for making C172 very easy and simple, Appreciate your efforts.
Excellent very educative and informative, Thanks.
Thanks for sharing this with me and having an up to date video

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

No. You just need the wheelbarrow volumen capacity for one drum mixer truck.
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?
It means your samples are taken between 10-90% of the batch, not the first 10% or the last 10%
@jayinla228 is correct. The video states it incorrectly and will be updated to state "after the first 10% and before the last 10%" soon!
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?
First 10% of 2/3 and not 90% of the 3/3
Can we use cube for sampling instead of cylinder
No, not for heavy or lightweight concrete. Either 4x8" or 6x12" cylinders are compliant.
2:30 is this correct?
if you mean the location of the sample being take, yes. It is worded different in various documents thought all reference the ASTM Standard.
