Fireproof materials expanded Perlite for lightweight concrete
What are Perlite ?
Perlite are not a trade name but a generic term for naturally occurring siliceous rock. The distinguishing feature which sets Perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from four to twenty times its original volume.
Character: Non-toxic, flavorless, lightweight, corrosion resisting, netural PH 6.5-7.5 etc.
Size: 100mesh, 200mesh, 0.15-1.18mm, 1-3mm, 2-4mm, 3-6mm, 4-8mm etc.
Unit Weight:(for reference)
- 1-3mm--------------60-90kg/CBM
- 2-4mm--------------60-100kg/CBM
- 3-6mm--------------60-100kg/CBM
- 4-8mm--------------70-110kg/CBM

Expanded Perlite
When Perlite is used as an aggregate in concrete, a light weight, fire resistant, insulating concrete is produced that is ideal for roof decks and other applications. Perlite can also be used as an aggregate in Portland cement and gypsum plasters for exterior applications and for the fire protection of beams and columns.
Other construction applications include under-floor insulation, chimney linings, paint texturing, gypsum boards, ceiling tiles and roof insulation boards.
