It looks like a reasonably full jumbo bag from a decent builder's merchant. I'm thinking of a 5:1 mix of ballast to cement. Anyone know how much cement I need for the whole jumbo bag of ballast?
Thank you,

PS The jumbo bag is of standard size, and is filled so that I can just manage to cover its contents by folding the upper walls of it over and inwards.

Need to know what job is ? That will advise the mix.
A GP mix using all-in would be done on 5:1 by volume
Mixes should be done by volume not weight ..... if you want a guide, bulk bag going to be around 750Kg
Thanks. The volume of the ballast looks to be very roughly about one cubic yard. Definitely less than a cubic metre. It's hard to guesstimate the volume of a bag of cement though.

jumbo bag is about 850kg
so at 5:1 6 bags or maybe 5...
It won't be a cubic yard; a full 800 kg bag of ballast is only about a third of a cubic metre.
Plenty of calculators on Google.

Thanks for the that. Looks must be deceptive then; what I've got looks like twice that amount. Al

Is this a new quiz? How many bags of ballast fit into a jumbo. I can see it now. things measured in animal sizes. Hang on I only have a giraffe of cement left mate. Brian
IIRC a Jumbo is a notional 800 kg, though it is often treated as though it is a tonne.
