not seen it done anywhere but the method I would use is take several samples of a known volume from across the heap and weight them so you can establish the mass
calculate the density of the samples
density = mass / volume
work out the 90th percentile of the densities and use that to establish an estimated weight for the volume of the heap
assumming you have a sufficent number of densities from across the heap this would be a robust method
if the make up of the heap is very hetrogeneous you will likely need a lot of densities

Subject: Estimating weight of demolition-type material from volume
Hi all
Could anyone tell me if they know of a rough estimation method that can be used for estimating the weight of material from its volume?
I have a site where hardcore materials (bricks and concrete and general demolition rubble in the main) have been imported. A certain weight was permitted but its importation was unregulated and now we have a large heap.
Is the method you use generally accepted? Has it been referenced anywhere?
I would much appreciate your thoughts.
Kind regards
Paul
