Now this may seem like a 'google it you idiot' question, but try it, I have spent several attempts to get the answer and all I am getting is 'x shovel fulls' 'the weight of the water', 'tonnes' and 'tons' !! just utter nonsense, its a simple question that should be answerable with 3 key strokes!!! the only variable is strength of mix, but this isnt gonna change the volume by more than 5% surely?, well within my tolerances, about 5/1 is my intended mix, so please, how many m3 is a bulk bag able to make???, I know its about 800-900kg.. ta..
