Here are a few concrete references that may help:

"Testing of Concretes, Mortars, Plasters & Stucco.  Arch Notes (Ontario
Archaeological Society), No. 1 (Jan/Feb), pp 15-23, 1989.

The Conservators at our Parks Canada lab have had some success testing for
mortar "recipes", especially in determining if it is pre- or post- Portland
Cement but I have never asked for help in dating concrete.  If the "recipe" has
changed over time, presumably analysis could determine this.

Hello HISTARCHERS,
I've been approached about an issue probably more architectural than
archaeological, but wondered if anyone could help.  A colleague wants to
know if there is a chronology for
concrete or any other way to date it.   Not really within my ken, sad to
say.  Any ideas?
Thanks, M.
