Name:   
Heading: 1.4.1Tests 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

Thanks to those who only called me a dummy in private replies. The correct answer is...

ASTM C94-11 Para 17.4 -

"17.4 Slump or slump flow, air-content, density, and temperature tests shall be made at the time of discharge at the option of the inspector as often as is necessary for control checks. In addition, these tests shall be made when specified and always when strength specimens are made."

I missed the last sentence.

Also give a look at ACI 301-10 1.6.3.2.d, which states, in part,that all the tests you spoke of will be completed on each sample used to mold strength specimens.
