Default concrete setting time

So long as you keep it wet, you can also hurry things along by getting
it hotter - so if the sun is shining for you, toss some plastic over it,
with a soaker hose under if needed. "Standard cure temp" is 70F - about
twice as slow at 50 F, about twice as fast at 90F, and darn fast if you
have an autoclave handy...

ie, 3-1/2 days at 90F and 14 days at 50F are both about the same as a
"standard" 7 day cure at 70F - so long as you keep it wet.
