Reply to comment by black_brook in Why does sand keep clay from shrinking as it dries? by UnderBridg

For the obvious case, there is less material shrinking. If the mixture is 50% grog, then clay that otherwise shrank by 10% should at most shrink by 5% since the sand won't shrink at all.

Also "grog particles don't shrink" does not explain anything because clay partials don't shrink either. They condense by sliding together like u/Indemnity4 explained. I assume the grog particles must block some of the clay particles from sliding together and affect shrinkage that way, but that is only an unexpert guess.
