Hi All!
Something I've never had to do so a little lost on who is responsible. I'm specifying a concrete mis with 6% air entrainment but the batch plant is only offering a mix of 2% and won't provide an air entrainment add mix design. The concrete contractor says he won't add a the mix in the field without guidance and testing. I can get the testing done on site by a 3rd party inspector, but can I expect the inspector to give direction on how much admix to use? Would this fall back on me as the SEOR? Thanks in advance!
 
Do a mix design and run trials with the batch plant. I think you have a communication issue since most ares require 6% air if exposure in the area requires it. You are leaving out information.
