20mm stone paviours outside.

I would do a much stronger mix for the sand and cement 10 or 8 : 1

Be too strong for semi dry too much cement and will make it brittle, and more likely to ball

that was the mix we used years back for warehouse floors mainly, taking heavy traffic.
but surely how well the mix was bedded / compressed when fitting the tile / stone has a big influence on how strong or brittle the cured sand and cement mix will be.

 

[J Sid]

if you over wet it , yes very likely to ball in mixer

Served half my time with pile of sharp sand, bags of cement, mixing board, barrel of water and a shovel for Toffolo Jackson. Don't know how many tons per day me and another apprentice mixed and carried. But tradesmen were scary guys back in that days and if they said 24 shovels to 1 bag cement guess what we mixed? Stuck with me all my life and never mess with it and never let me down

what was being fixed on top?
factory floors or outside paving?

Inside and out

Sorry should have pointed out that was the old big bag of cement ratio which would be equivalent to 2 bags nowadays forgive me the minds going!

Do you know why it was spec'd that way John?

Because I wasn't happy with the way the contractor expected the job to be done so he asked the stone supplier how they recommended it be done!
That's what he came back with so now I'am thinking do they want it fixed by a landscape gardener or a tiler - so I may have to get my wellies on and get a rake or instead go and do a few nice little victorian jobs.

 

[Time's Ran Out]

Just an update - this is how it turned out - as per suppliers specification.

That's when bags of cement weighed 1 cwt/ 50kilos. So l recon that's a mix ratio of about 1 to 6. Once worked on a site, where Toffolo Jackson, where fixing terrazzo wall and floor tiles, aye the apprentices, had to graft. Probability back in about 1970 ish.
Was working for a builder. On burnt field road in those days, where Toffolo Jackson also operated from. ( oh, the old days).
