Hi
I have 1/2 tonne bag of fine building sand and almost the same of sharp sand left over from a project.
Can I put it in the sandpit for the kids to play with - is there something different about play sand.
Thanks

Heh. I have a tonne of playpit sand that is useless for building - we should do a swap!
Sharp sand is much more abrasive - there are bits of jagged stone in there which will stick under fingernails and cause grazes.
Also, it will tend to stain them yellow.
It depends how picky you are, really.
Do you want your kids to turn orange? Mine did when I had the same idea.
Not a lot after a few days rain to wash away the clay and a few nights of the neighbourhood cats to add flavour.
Yes. Its washed to get the stains out and its smooth so it doesn't scratch.
Oh, its not useless at all, especially with white cement where its lack of colour allows a very pale mortar colour. Mix in some lime as well, and you could swear it was lime mortar, except it actually has strength.
Top cats prefer sharp sand. DAMHIKT.
We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember bp saying something like:
Do you have the necessary amount of cat turds to add to it?
When I was installing a mooring point for a boat, which was half and oil drum buried then filled with concrete I ask the owner of the next door boat if it was ok to use that sand from the shore. His reply was it was fine for that job, but would not be good for, say, a bridge, and concrete/cement made from sea sand was nothing like as strong.
I suspect that's not the sea _sand_ so much as the contamination with sea _water_ that's the problem. I think it messes up the reactions.
But can I find a reference to back that up? Can I heck.

That's odd - when I was researching ferro concrete boats a few years ago, the received advice was that sea sand with it's salt 'contamination' made not a jot of difference, and if you were building on a sandy beach then use it. Mind you you can't do that in this country as the bit from low to high tide belongs to the crown so the Queen could bang you up the the Tower
