The Colorado Ready Mixed Concrete Association (CRMCA) is a Colorado based organization representing the interests of Colorado’s ready mixed concrete producers.

Founded in 1956, the CRMCA promotes the use of concrete both in traditional construction and paving applications as well as the latest concrete solutions such as insulated concrete forms (ICF’s ), colored, stamped and architectural concrete, flowable fill, and Pervious Concrete.

if you mean the location of the sample being take, yes. It is worded different in various documents thought all reference the ASTM Standard.

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.

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?
@jayinla228
@jayinla228 4 месяца назад
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!

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?

No. You just need the wheelbarrow volumen capacity for one drum mixer truck.

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."

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?
@nathan_steffen28

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

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.
