Sandeep,
The recipe below will work very well as an insulating refractory for rocket stove. Make the mixture and then shape it into slabs. 
Kind regard
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.
