What is the story with concrete additives? I read different things about whether or not they apply under IEQ 4.1 or 4.2 It seems the MFG likes to tout it as "LEED Compliant" if it has a generally low VOC level even if in does not fit neatly into a SCAQMD or GS category. The job I'm on now is a climate controlled parking structure so it is not really outside. Does everything I put into my concrete or shot-crete have to comply with some VOC limit? if so what is it? 250? 350? 100?

I've never included them and I think that is a reasonable strategy not to. An admixture is a small quantity relative to the rest of the concrete components and is quickly encapsulated.
