Where can I buy refractory CONCRETE?

[Fio]

I have seen some on this forum use refractory concrete for castings and plugs (i.e. Kiwi Pete). I would like to do the same thing, but I cannot locate a source of refractory concrete or calcium aluminate cement.

I live in a fairly large metro area (Washington, DC) and I'm surprised I cannot find refractory concrete anywhere.

I DO have a source for fireclay and Heatstop refractory mortar. Can I just add some aggregate to the refractory mortar and use it in place of refractory concrete?

If not, where the heck can I get some refractory concrete?

Thanks,

I am planning on using a catsable product from a company called Pryor Giggey.

The product I decided on is called Econolite, it is an insulating castable good to 1600 deg F. They have one called Insulcast which is good to 2600 deg f but it was substantially more expensive. I am planning on using it for the vent area.

Here is a list of distributors, maybe call one of them and find out if they distribute to a retailer in your area.

Pryor Giggey Refractory Distributors

Looks like they take orders online as well...

Hope that helps.

Go to ANH Refractories and see if they have a local distributor in your area. I sourced my Mizzou Castable Plus from them.

Be careful, if you are casting any part of the oven shell, that you do not get the more common insulative refractory castible. For vents and flus pretty much all of them will work.

The Mizzou was $0.66/lb for comparison.

Enz,
A lot of refractory materials: ceramic fibre insulation, calcium silicate board, high-temp adhesives, and castable concrete are available from McMaster Carr. They are happy to sell small quantities to individuals. Even if you don't buy from them, their web page is an outstanding resource for specifications and to get an idea "what's out there". Give it a try.

Seb, you responded to two posts from over two years ago. It is possible the suppliers that were listed are no longer in business.

Try a Google search of refractory suppliers in Colorado. You can probably find refractory mortar (such as Heatstop 50) at your local masonry supplier (brickyard).

A quick web search shows that this product was made by A. P. Green, which was absorbed by Harbison Walker, now doing business as ANH refractories. A quick call to ANH will tell you if they still make the product, or what the ANH equivalent is.

Remember: In the US, castable refractory is FAR more expensive than firebrick.

In the local Yellow Pages (in the USA) check a number of categories:
- Refractories
- Fire Brick
- Boilers-New & Used
- Heating Equipment & Systems-Repairing
- Heating Contractors & Specialties
Also, if you have a home heating furnace (oil or gas), contact the people that normally service it for you. They might know a good company to contact locally (or relatively close by). That is how I found the supplier for my air-setting mortar and cal-sil board (1 supplier), and #1 Arch Super Duty brick and a torn bag of high-strength castable refractory (another supplier). The later was not an insulating castable and I used it in forming the very top of my dome (last 'row' and the plug).
I did a web search for "General Insulation" and discovered a local warehouse and got a good price on Mineral Wool blanket for insulating the dome.
