A 1:6 (one part Portland cement by volume to 6 parts perlite by volume) mix would be appropriate and add enough water to make it easily spreadable, but not so wet that it is dripping. I am curious, based on your experience what a 1:6 ratio would weigh to level that section? Perlite concrete can weigh between 20 and 09 lbs. per cubic foot ...

Perlite concrete, while not usually suited for structural or load bearing uses, o˚ers many advantages beyond its light weight. Perlite concrete provides better noise reduc-tion …

How Perlite Helps: By integrating perlite into the mix, the weight of concrete can be reduced by nearly 20%. The resulting lightweight concrete maintains robust strength but is easier to handle, faster to set, and, crucially, puts less stress on the structures it's used in. This lightweight solution is perfect for floor fills, roof decks, and ...

Use a 5 gallon bucket, mix 1 part cement mix, 1 part sand, 1 part perlite and 1 part peat moss. Altogether it should come to a total of about 18 cups of each ingredient. You may find it much easier to mix this …

This is the first part of the build things didn't go according to plan but that's part of the fun eh? Perlite is a low density volcanic rock which is used for it's insulating properties in building and also gardening. It's really light but a great insulator and so our insulation layer is made by mixing 5 parts perlite to 1 part cement.

1 part Portland cement 1½ parts peat 1½ parts perlite. This recipe is suggested if you want the ability to carve a pattern or design into the 'tufa. It is workable while still quite damp. This would also be a good basic "granite look" recipe. (Use white Portland cement.) Basic Hypertufa Recipe B 1 part Portland cement 1½ parts peat

The lower the density, the higher the insulating value. For most uses to maintain a proper balance between insulation value and compressive strength, a 1:6 (one part portland cement by volume to 6 parts perlite by volume) mix is chosen with a density between 24-30 lb/cf 3 (384 and 480 kg/m 3). This provides a k factor range of 0.58 to 0.66 Btu ...
