1 cubic metre of concrete has a weight of 2400kg and 15% of it is water.
The rest of the ingredients of concrete are cement, sand and stone in a ratio of 1:2:5.
As 15% of 2400 is 360 and once you take that away you have 2040, would that mean the weight of cement=255kg, sand=510kg and stone=1275kg?
Just went on Yahoo answers, apparently my conclusion is perfect. :3
