Re: Epoxy granite mill head support beam
Thanks thanks for sharing your work and (maybe again?) sharing Thomas' spreadsheet, I'd been trying to find it.
I entered some values but in looking at the results a BIIIIG question mark appeared.
I entered the specific density of the sand in each row, at 1700 g/liter. It is a value I found at some point and should be more or less the same for each grain size.
But at the end I found that one litre of the mix of grains still weighing 1700 grams.
Shouldn't that be creeping towards 2700 (density of quartz), as the point of mixing the grains is filling all voids between the grain with smaller fractions?
