glueing shell grit together

i am trying to propagate coral and i want to make some shell grit plugs

to glue the coral on to. i know of a shop on the Gold Coast, AUS that
makes them,
but i need to know what type of glue i can use to glue the shell grit
together. it looks like a plaster of paris but that would just break
apart under water wouldn't it? any help would be appreciated.

Yes it would.

You need portland cement. Make it somewhat wet, and mix in
just enough into the shell to lightly coat it.

From the GARF website;

PROJECT OF THE WEEK
Building a reef plug mold for making aragacrete reef plugs.
MATERIALS:
1 piece 2" x 12" lumber 24" long.

TOOLS:

Drill press or hand drill
1/2" wood bit
1 1/4" step bit - this bit is shaped like a sander cone with 1/8" steps.


INSTRUCTIONS:

Lay out the 2" x 12" board with holes 1" apart.
Drill pilot holes on each center mark.
Finish the holes with step bit.
Be certain the holes go all the way thru the mold.
Sand the mold smooth with 220 grit sand paper.




These molds can be made any size that easy to work with. Use wood that can
be soaked such as fir or clear pine. A drill press is the best tool for the
job. A hand drill can be used, but a simple drill guide will help you make
the holes square with the mold.




MAKING REEF PLUGS:

MATERIALS:

Carib SeaTM aragonite sand.
#3 portland cement

INSTRUCTIONS:

Presoak the mold in water for 1 hour.
Mix 5 parts Carib SeaTM aragonite sand with 1 part portland cement.
Set the mold on a smooth surface and pour in 1/2 tablespoon dry aragonite
into each hole.
Pour the aragacrete into each hole in the mold.
Let the aragacrete set for 24 hours before you push the reef plugs out.
Soak the reef plugs in white vinagar for 12 hours and rinse them in fresh
water before you use them.

Unless you live in a place where there is no concrete
buildings, or concrete sidewalks, then you should have no
problems finding portland cement :-)

It is a key component of concrete. Try a building supply store.

That may be so but what name might it go under here?

Hi fellow Aussie,
There is a great Australian forum
http://www.masa.asn.au/phpBB2/index....7c7a4f5707aaf5
which makes research a whole lot easier. masa is the marine aquarium
society of australia and the forum is called rtaw, reefing the
australian way.

I spent months researching, before finding the Aussie forum, only to
find out that many things are different here to what the Amercians and
Europeans have access to. If you are in Qld you can join the MASQ
(marine aquarium society of queensland) for just $10 which will give you
5 and 10% discounts at many online and realworld stores. They also have
meetings but mostly in Brisbane and too far away for me. From what I can
gather the meetings involve frag swaps too.

Portland Cement.

It will be on the same row as the mortar, and quickcrete.
