What is silica sand used for? I have 4 25kg bags that were left at my house
by the previous owners.

Sandblasting, kids sandbox, brushing into cracks in asphalt before
overcoating, ingredient of concrete.

Sand blasting.

Do a GOOGLE for "silicosis" and then decide what to do with it.

Adding to what everyone else has suggested,
some grades are used to decorate aquariums.
Granted, 100kgs seems a bit much for that...

Swimming pool sand filter?

NEVER NEVER use Silica sand for sand blasting, you'll just DIE!!!!! After
flailing around for awhile due to lack of air!

don't breath the dust.....serious health hazard associated with silica
dusts.

Better stay away from the beach, then.

Some proof? Website or reference for your claim?

Ever try Google? 180,000 hits on "silica sand danger"
http://www.buildsafe.org/hazalerts/KFsilica.pdf

http://www.osh.netnam.vn/html/silico/SILICA_HK.html
Silica is the most abundant constituent of the world s minerals and rocks.
It occurs in two forms, free and combined. The

combined forms, or silicates, do not usually present any serious hazard to
health. On the other hand free silica, or silicon

dioxide, does present a health hazard and is the subject of this booklet. It
is the common constituent of quartz, granite,

sandstone, sand, flintstone and slate.

Prolonged inhalation of high concentration of dust containing free silica
will cause the lung disease known as silicosis. This disease is serious and
may lead to a permanent incapacity for work in the affected person; it may
also be associated with an increased danger of contracting tuberculosis, or
aggravating tuberculosis already present.

• Do not use disposable dust masks if the dust has any silica. Disposable
masks do not protect you from silica. They do not form a snug seal with your
face.

• For abrasive blasting, replace silica sand with safer materials. The U.S.
government's National Institute for Occupational Safety and Health (NIOSH)
says do not use sand or any abrasive with more than 1% crystalline silica in
it. Specular hematite, crushed glass, some slags, or steel grit and shot may
be good substitutes. (Use of some slags and steel grit may increase worker
exposures to some toxic metals.)

Stay away from the beach, or don't breathe if you go there. And anywhere
coastal in Florida. Carpeted with silica.

Carpeting the beach is a little different that blasting it against a hard
surface with 100 psi of air though, creating fine dust.

besides the water is dangerous too!!!!!!!

Tens of thousands of square miles of silica sand being ground upon itself
by wind and wave. Yes, a little different indeed.

Beach sand started out as big rocks. Ever wonder why it is roughly uniform
in grain size?

Glad you got my point. The water washing away any dust is much different
than airborne very fine silica. It is not skin contact that is the
problem, it is the very (extremely?) fine particles that get into your lungs
that cause the problem. You get that with blasting, but not in a water bath
that takes it away.

See, I knew we'd agree on this.

My beach is about 300 ft wide, with about 30 ft washed by waves. The rest
is just blowin' in the wind.

If the surf is somehow a magic dust trap, then it certainly doesn't show
it. The surf zone floor is a quite uniform large grain size.

And I live 6 miles inland on about an acre of what was formerly the
Everglades swamp, which was formerly a beach, which was formerly under the
ocean, depending on how many zillions of years back you go. If I dig a
hole, I bring up prehistoric conch shells. In short, a soil that is
chiefly silica sand, which in today's drought index of 502, is blowing
quite a bit of fine silica dust. *Cough*

And not very dangerous compared to sand blasting. Silica, like asbestos, is
not a problem in skin contact. The problems come from the friable dust that
is very fine and in enough concentration gets deep into the lungs. Any
matter can cause problems if very fine. Blowing beach sand is not always as
fine or in the concentrations of a guy doing sand blasting for a few hours.

We breath in all sorts of crap every day but most is easily filtered by nose
hairs (makes big boogers) and other parts of the lungs and is expelled. The
stuff that gets by the normal mechanisms of the body are the ones causing
problems.

Do a GOOGLE for "silicosis" and then decide what to do with it.

A Google hit gave me this:

Simple chronic silicosis -- results from long-term exposure (more than
20 years) to low amounts of silica dust.

This is just a few weekends at the beach every year, isn't it?

Right, sez me and my practical experience with very windy beaches and sand
blasting.
