Compression, yes.

Stiffness is the goal, and an RC board can be made to any stiffness you 
like to accommodate any realistic bearing schedule that pleases you. The CC 
board will be as stiff, and only as stiff as the expansion of that 
particular panel provides, will be much more erratic from panel to panel, 
and is as a result more limited in the downbearing ranges it will accept 
and still function for a reasonable length of time.
