Hello,
I’m in the process of ordering my perlite for my fire brick base.
The mix is 1:6 portland cement and perlite. My question is: Is this only portland cement and perlite, no sand needed for the mix?
Thank you!

Yes, no sand or aggregate is used in this mix. It is just Portland cement and Perlite. The cement is there to hold the Perlite in place and provide a stable surface for the leveling sand that goes over the insulation.
