Durability of Sand/Cement Pool Floor Mix

[nobbyv]

I have a liner-over-steel wall kit I bought from PW. They recommend a mix of ten parts sand and one part cement for the pool floor. I understand you can't have rain while it's setting up, but once it's cured, can it get rained on? I guess what I'm asking is how solid will this be.

I do not know but lets see if @jimmythegreek is around to provide you some input.

I have much of that as decking base. It's common to use the portland/sand mix, wetted, and plate packed. It becomes very dense and stable, but you can chip and dig with shovel.

It's a glorified.samd base. The small amount of Portland helps it stay packed. It's gotta be done and liner set no rain otherwise your up the creek with crusty sand
