have had some ready mixed cement stored in a shed for about a year or so.
although it's a bit solid, if i scrape at it, it then goes powdery, so i
could mix it up.
could i use this old mix for anything? someone has told me if i do it will
not have much strength? but even so i guess there are little jobs around the
garden that dont require much strength?
is it likely to be of any use please?
You could mix it up, but it won't have any strength when it sets. You see,
cement cures by a chemical reaction with the water that's added to it. In your
bag of old cement, that reaction has already taken place, with humidity in the
air. You can't make concrete with that stuff. It will set, but it will crumble
the first time any stress is applied to it.
Sure - if your soil is too acidic, you can mix some of that cement into the
soil to make it more alkaline.
In the winter, if your walk or driveway is covered with ice, you could spread
some of it around to provide traction, and possibly help melt the ice.
If you have any plants you want to kill, you could dump it on top of them.
Not for making concrete. Just buy some more. It's cheap.

Nobody ever left footprints in the sands of time by sitting on his butt.
And who wants to leave buttprints in the sands of time?
If you have a gravel driveway, just spread it into the gravel with a rake
and let it add to the pavement filler.
If you are setting posts us it at the bottom where it doesn't need strength,
it can act as filler there.
You could try selling it to Barratts to go with everything else that's
substandard about their houses, or you could mix it up and make some half
pound balls to throw at Tony Blair when he comes round to your area on his
election campaign. They won't hurt him, they'll just crumble on impact.
In other words, I don't think it'll be any use for much else.
