What is "man sand"?
I have been building for 20yrs and heard a lot of weird things, but this one has me curious.

Another example of why a person needs to put in their location......
I live in California and even I don't know what that means......
Is it a 'down under' thing?

Ya know, the older I get the dumber, I think, I get when I read stuff like this, so I ask. Dad always said, "If you don't know, ask". Then I read that there are others that don't know either, and then I don't fell so dumb. Thanks guys. I don't know if it is a down under thing b/c THERE IS NO LOCATION GIVEN!!!

Is this related to using flashlights on the beach at night?

Back to the topic, I used about 10 ton,s of sand (dry) from a sand blaster and spread even on a 24' X 32' shop floor, the only advice from my concrete man was to put a vapor barrier over the sand or it would **** the moisture out of the concrete and cure to fast to finish properly. Another advantage to the barrior is that the floor don't sweat with weather change.
Dry sand don't settle like wet sand does and that causes voids under the floor.

man sand, stands for manufactured sand, it is the by product of when they crush rock to make the different sizes for the different uses. I personally have used man sand for sanding sidewalks and parking lots during the winter.

Around here it's called stone dust and that's what I have under my garage floor.
It packs very well.
Stone dust mixed with 1" stone is also good and great for driveways. It's usually called pack, gravel, crusher run, etc. (seems to vary by location and gravel pit).

OK, so this is a real question. Manufactured sand probably isn't the best choice because it is usually free of fine material and silt. The silt content acts like a binder when compacting the soil. The "man-sand" is angular because it is crushed stone, so it will compacted somewhat, but not as good as a material with fine content.
Look at the specs for the sand. A good indicator for the fine (binder) content is the "loss by wash" percentage. Sometimes it is stated as "% passing the #200 sieve. A number in the 5 to 12% range or higher can have decent compaction ability.
Here it is called "lime" because it is crushed limestone. It works quite well. Get it close to what you want for finish grade minus about 2". Soak it down with a sprinkler over night and let it dry for a day or two. It will be a very solid base. Then finish up your grading with 3/4" clean. Put down a vapor barrier and pour your concrete.

This is a perfect example of why the place is so great.....learn something every day....
On another note.....I'm glad there is a good explination for "man sand".

ducati...When you say, "Then finish up your grading with 3/4" clean..." What is this. Not trying to be a smart a--, but what is "3/4 clean".....please. Just trying to learn. Thanks.

Pure sand shifts under concrete. Around here it does that by sifting down in cracks that open up when things get really dry, like the drought we've had for several years.
We prefer a substrate of ungraded crushed rock simply called "base".

3/4" clean rock. There are different types levels of fill. When you call a quarry, they will have "lime" or "crushed stone" which is just all the little chips from making different grades, Then they will offer a "x" minus which will usually be like a 1" minus for like gravel drives or a 2" minus for gravel roads. What this is saying is you won't have any bigger stones than what ever the "x" minus is. The smaller stones will make it pack better and help hold it in place. Then the last catagory will be "clean". This means all the rocks will be the same size which will be easier to make all uniform because they are all the same size. The problem with clean is since it is all the same size, it won't stay in place because there aren't smaller stones locking it in place. Clean makes it a lot easier to grade before you pour concrete on top which will stop it from moving.
