weight of materials

[Unregistered]

Does anyone know of a website that has weights of materials. I need to know the weight of 3/4 clean stone, sand, topsoil and other construction materials so I can convert yards to tons. thanks.

Try this list here:

They have alot, though not everything you asked for I think. You may need to be creative when searching, for example search for "earth" instead of "topsoil".

What might the weight per cubic yard of crushed concrete be (4" minus)

It lists concrete gravel at 150 pounds per cubic foot. Nothing exactly like you are looking for though.
