Perlite: What It Is And How To Use It Right
The typical chemical composition of perlite varies slightly, as most volcanic glass does. However, perlite which is optimal for the expanding process typically consists of 70-75% silicon dioxide. Other chemicals include: aluminum oxide (12-15%) sodium oxide (3-4%) potassium oxide (3-5%) iron oxide (0.5-2%) magnesium oxide (0.2-0.7%)

Perlite in Construction: Reinventing Insulation & Concrete
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 ...

What is Perlite: How to Use Perlite Soil to Grow Plants
Perlite is sometimes called volcanic popcorn due to the processing techniques used to make perlite. The volcanic mineral is heated to 1,600°F (876°C), where the perlite expands and "pops"—similar to making popcorn. It can expand up to 16 times its original size. Looking under a microscope, you'll see that horticultural perlite is ...
