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 384 and 480 kg/m3. This provides a k factor range of 0.085 to 0.095 W/m-k and a compressive strength of 125 to 200 psi (986 to 1378 Pa).
