concrete aggregate correction factor 1

[QCtech]

I have recently gone through the CCRL inspection. The correction factor for air content in the aggregate and sand is a hit we took. I have called several local suppliers/associations and have had no real feed back. Other than going to the how ever many quarries (whether barged or excavated) to sample the material ourselves is there any other way of gathering this information?

This is a really good link for concrete mix design... The program is java script and you can copy it and load it as an html file...
