Sounds like cause and effect to me.  Pecan, Carya illinoensis, can have
 a spread of from 40' - 70', from what I've read.  A tree's roots can extend up to 3
times it's canopy (spread).  So depending where and in what position you 
poured the new slab, this may be starving the small feeder roots of air and water.
I'd guess the falling branches are dieback at 
the furthermost  tips of the larger limbs.  This is where root damage shows 
itself, being furthest from the roots. ( I wonder if the dieback is occuring in the 
same general area of the slab as I suspect.)  You could always contact an 
arborist who may be able to look for 
insects or diseases or call Extention for their local scoop on what 
should/shouldn't be happening to your mom's cool old tree.  
Good Luck, Constance
