Hi 4stroker and david s thanks for your time in putting this together.
I'm just making a few modifcations for info i've come across and for our fellows across the pond and wondered if i could ask something in relation to Note 1, points A and B.
If you have a volume of 1800ml of 4 things prior to dry mixing, and a net volume of those 4 things as c. 1350ml after dry mixing, your net volume is 1350ml. So, when calculating approx water input of 400ml to further reduce the volume to c.1260ml, you're essentially adding the water to the mix (1350ml), not the components (1800ml) separately.
In your excel sheet you work out the 'Approx. total volume of water required' as 'The total dry volume of materials required' (1800ml) * addition of water (400ml) = 0.2222
Should it not be 'Approx. total volume of water required' as 'Resultant volume of materials required' (1350ml) * addition of water (400ml) = 0.2963?
This would in theory make your final density reduction calculation as 'final volume after water addition' (1260ml) / initial dry resultant volume (1350ml) = 0.9333 (not the 0.7 you have in the spread sheet)
I know this is probably minuscule in the calcs but want to make sure i'm thinking correctly.
I hope that's clear as .... clay.
Thanks
