Internally cured concrete has been shown to be effective in reducing the potential for plastic shrinkage cracking of pozzolanic concrete mixtures like Fly ash. Anybody found its significance in the case of high volume replacement by slag?

I found your question rather puzzling.
First, internal curing does not reduce chemical shrinkage. In fact, it even increases chemical shrinkage, since it increases the degree of hydration of the cement (in low w/c mixtures). Perhaps you meant autogenous shrinkage instead.
Second: why are you mentioning "freezing areas" in the main question when you are then speaking about plastic shrinkage cracking in the explanation?
It would be better if you clarify your question if you want to receive meaningful answers.
Dear Muhammad,
A good question. The following article talks about internal curing in a mix with partial replacement of Portland cement by slag. It may not answer your question completely, but could hopefully help shed some light:
