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,
