I've searched on the internet but I'm having trouble finding 'real

long it will be workable and thus when you have to finish a mix.
However finding when it will be acceptably hard and strong is more
difficult.

So, at present, with outside temperatures in the 5 to 10 degrees
Celsius sort of range (hereabouts anyway) how long should I be
expecting my cement to take before being reasonably hard? I know it's
upwards of a month before it has reached most of its final strength
but I want to know when I can put weight on slabs supported by
concrete and when pointing will be strong enough to walk around on.

Two to three days seems a reasonable guess but is that for warmer times?

Thank you, those are useful.
