Ultra Newbie Cement Mix Question

[TheScullster]

Hi all

This is going to sound real daft but: The mix ratios given for sand/cement/gravel are they by volume or weight?

TIA

They're by Irish navvy shovelfulls.

[John Rumm]

which for the avoidance of doubt, is by volume!

[John]

Volume i.e. 1 shovel of cement, 2 of sand and 4 of gravel

see

for more details.

I'll take that as volume then :-) Cheers Dave

It might be useful to say it's by volume because the weight of sand varies significantly depending how wet it is.

[OG]

As has been said, mix ratios are by volume, but there's not a lot of difference between the density of gravel and cement (so you can buy it by weight and mix it by volume).

Sand depends on how damp it is, dry sand is similar to gravel, cement, but damp sand can be 1/4 heavier or more.

BTW I don't know this stuff, I just found it here

Oh dear, I was going to ask how much sand, gravel and cement I would need for a given vol. of footings. I can't now, I've got the data I will have to work it out. :-(
