Our project has a milan wall wich has some water filtrations, a mortar made out of cement and an additive is being used to seal these filtrations. The additive consists on a powder added to the concrete and it is used to accelerate the concrete's curing process, that's the only thin the additive does to the concrete mixture. Since it is an additive that at the end is "fixed" in the concrete, does it have to comply with any certain VOC limits? It is not a sealant, it just helps the concrete cure faster. Any information will be appreciated.

Michael, I'd say that a concrete additive is not expected to come under examination under this credit.

The product you are looking at is referenced in 1113 as a Concrete Curing Compound max 350 g/l.

John, one more question. What about a waterproof additive? This is a powder that is mixed with the concrete mixture and gives it waterproofing properties. It is not a coating so it has no primer or anything, like I mentioned, it is just a powder added to the concrete.

Michael, I'd either say "Other" or I would consider it a concrete admixture, and thus out of the scope of this credit.
