Uses for fire brick dust

[s988rt]

Hi All,

Any ideas for using fire brick dust left over from fire brick cutting?

I've been cutting bricks as needed and have developed quite a pile of residual dust from the tile saw.

Can I use it to fill small gaps in my oven floor between bricks? Are there other, better uses? Should it be applied dry or wet?

Thanks!

You can use it as a fine aggregate for your mortar.
