A hero on this group has lent me a minimix 150, i'm just wondering how
much you can/should shove in one.
*Should* I think is 90k, so given the mix below (1/2 cement 3 sand) plus
water that's probably a little over, it's tempting to chuck more in
though as it appears there's room.

And while on the topic when sorting a mix, is a 4:1 ratio based on
weight or volume? Because a bag of cement appears to have 50% more
volume than the same weight bag of sand.
So a 1:4 mix (per the shovel) would be 1/2 a bag of cement to 3 bags of
sand?
