either it sets like rock or it doesnt. If it does, it does its job of
setting like rock. That may not be good enough spec for bridge
building, but for setting posts its more than enough.
You just don't know, and anyone who claims they do is telling porkies.
But Adam said its been a few months in the lounge, so no worries
there! You can keep cement a few years in dry storage and it still
sets hard.
A room with 50% - 70% humidity is NOT dry storage.
A lounge with 70% RH would be unusual, and not one to put
cement in.
And as I pointed
out above, cement that appears to you to be "setting hard" can have
lost as much as 90% of its strength. Furthermore, its capacity for
watertightness will be severely affected.
Cement is not that expensive, certainly not worth taking this sort of
a risk on. Except if you don't know what you are talking about, so
please feel free go ahead and use the stale stuff, as you will be none
the wiser. ;-)
Some of us here have done, and it works fine for undemanding
apps. Those of us that have tried it know that.
