Mortar mix ..... just add water

Mortar mix is sand and portland cement.....Refractory mortar mix is a specialized mix of sand and other ingredients....

...but if it comes as a mix, I think it's pre-prepared and you're good to go.

Jump in if anyone disagrees.

I agree with Jim.

Where did you get that mix?

Re: Well i quess im building an oven!

Thanks guys! dmun i thought the same thing silica = sand, but you know how second thoughts are! And they never have mixing instruction! Ill post some pics in a bit, ive got three courses done and tommorrow i will figure out and assemble the door arch. I have come to see that the fire brick i got from work is probably medium duty brick, when i cut it open the density was far different than the brick i bought. Because they are tapered to begin with i thought i would use them on the last few courses. I hope they will be alright for oven use!

From a company called ixl brick.

Yeh that looks like a normal airsetting refractory mortar. If you need, "fatten' it up with sand but shouldnt need it. Sand would give it a bit more guts.

Oh Man, I hate to jump in late here, but doesn't air set mortar mean that it continues to be able to be dissovled by water and therefore unsuitable for outdoor use?? I saw that it was a dry mix so did not think anything of it...usually the air-set mortars come premixed...

Yikes.

Doe's air-set mean it needs heat to harden?
Like a kiln temp heat?

Re: Well i quess im building an oven!

I'm checking google.
It looks to me like an air set mortar is what you want to use.

Not sure yet....

After proper mixing and air drying, heat stop 50 is non water soluble.

Quote from the back of the bag. It does say it isn't waterproof, but non-water soluble means it won't run away like a sand castle when the tide comes in if it gets wet after drying.

Breathe. Since what I'm using says specifically "air drying", I am assuming that what you're using is the same.
