With the help of the trend lines shown in Fig. 2, the on average 1.95-fold higher compressive strength of the perlite lightweight concretes becomes apparent. Especially in density ranges from 1100 kg/m 3 to 1200 kg/m 3 the mixtures M1 to M7 seem to outperform the aerogel concretes used for comparison.

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.

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, offers many advantages beyond its light weight. Perlite concrete provides better noise reduction and …

Perlite concrete mixed at a ratio of 1 part cement to 6 parts perlite has an insulation value, or "k" value, of 0.64 and a compressive strength of 125 to 200 pounds per square inch. At a ratio of 1 part cement to 4 parts perlite, you achieve a "k" value of 0.83 and compressive strength of 350 to 500 pounds per inch.

The first part of this experimental study was devoted to the choice of the proper mixing procedure for expanded perlite concrete (EPC). Thereafter, six sets of cubic specimens and six sets of parallelepiped specimens were prepared at a water-to-cement ratio of 0.70 with varying replacement percentages of sand by EPA ranging from 0% to 80% by ...
