[Stoves] Mortar Mix Recipe?

[Zietsman, Rex]

I have just made a mortar mix out of the following:

 

Primary Mix - by weight

75% clay - I bought some at a potters outlet

25% fine sand - I used plaster sand sifted to keep out rubbish

Enough water to make mushy, well mixed mixture

 

Final Mix

1 volume primary mix 

1 volume fine sawdust - screened to remove large particles

 

I then formed the final mix into triangular shaped bricks, dried them
and fitted them into the frustum (chopped off cone) section of a furnace
made from steel. I used straight clay as filler between the joints. I
also made a 1" thick wall pipe using a cut off tin for the outside and a
piece of PVC pipe for the inside.  The mortar pipe fitted into the
furnace outlet pipe fitted to the bottom of the cone. Mounting the
furnace on bricks (to let air in from the bottom), we made a serious
covered fire inside the refractory to cure the lot. It has come out very
well. Anyone looking for photos, send me a mail and I will email them to
you direct.

 

Kind regards

Rex

Greetings!

I plan on building a rocket stove/masonry heater. Can someone
recommend a mortar mix recipe for the firebrick, limestone and blue
slate?

Thanks,

Jay Scott.
