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?
