Er, no. See Cormaic's pages. When done right, it will last for
decades and often centuries. For millennia, you need a better

Which is quite likely to crack in its turn, thus leaving you with
an even thicker mass of concrete to deal with. Also, if you have
any services underneath, or don't know that you don't, laying on
sand allows access with low hassle.
