The evaporation of the water causes the chemical reaction.
To delay the setting, you can add more water, but then you wind up with
gravel in very runny concrete that doesn't stick. If you don't add water,
then eventually the concrete will set, even being agigated. It just won't
stick to anything. You'll have a whole bunch of gravel covered with a thin
layer of concrete.
