Vermiculite concrete normally compresses up to 35% without disintegrating. This property has been utilized in underground mines where vermiculite concrete has been used to infill cavities and to build ventilation walls. These walls deform and compress without shattering when under pressure from the surrounding strata. Floor and Roof Screeds

Why Perlite Works. Genesis in Fire Rapidly heating perlite ore to temperatures of about 900°C (1,700°F) softens the volcanic glass causing entrapped water molecules in the rock to turn to steam and expand the particles like popcorn. The expanded particles that result are actually clusters of minute, lightweight, insulating, glass bubbles.

The Benefits of Perlite as Insulation. When perlite ore is expanded by exposure to rapid, controlled heating, it grows up to 20 times its original volume and takes on a foam-like cellular internal structure — essentially clusters of microscopic glass bubbles. This physical transformation makes expanded perlite an extremely efficient, low ...
