an explaination is here:

There is a point though where wet sand would be lighter, just need to define how much water is in there, obvious really as water is lighter than sand. So when you hear things like this that at first seem to be outrageous, you just need to step back and have a good think about it!

Astro for that to work you have to assume that the water is a solid and will displace the sand but last time I got a soaking from the stuff it was still a liquid therefore no sand is displaced and the water fills the gaps between the grains and makes it heavier the fella who wrote the article even says that at the end which begs the question why did he bother writing it if he disproved himself at the end. You could say he was being hypothetical a bit like me saying if I were 12ft tall then I would have an 18 inch p~nis I'm not and unfortunately I don't. Nuff said :p

i was benching a manhole today and i mixed water to the already damp grano, sand and cement. now when i use a mix with the right amount of water the benching stays where i put it. but the wet mix wants to bulge and sag. proof therefore that wet is heavier than dry, or moist.....i think ???

Not nesser celery.

The increased amount of slump resulting from additional water is due to fluidity rather than mass. A wetter mix has more liquid per unit volume than a dryer mix. The definition of a fluid is "a material that flows", so liquids and gases are fluids. You have more liquid in a wet mix, therefore it is more fluid, therefore it slumps further.

Did you know that glass is a fluid?
