Heading: 1.5Tests to accompany compressive strength?
Message:
It used to be that either ASTM or ACI had a statement that if you were making cylinders to check for compliance with specified strength requirements you had to also run a slump, air content, concrete temperature and unit weight. I found a reference to requiring concrete temperature, but not the others.

Does anyone recall what document and section has that requirement? It may be gone now.

Thanks,
Jay

Jay,

Check ASTM C 31 and C 94. Unit weight was not required but slump, air content and temperature were. It is interesting that some folks would ignore the air content test if the concrete was supposed to be non air entrained. But my question always has been how do you know it is not air entrained unless you test for air content?
