Perlite is probably the medium ingredient having the highest air-filled porosity (Schindler et al., 2017). Burés et al. (1997a) reported that water retained at −10 kPa is much higher for the coarse fraction (0.5–1.0 mm diameter) than for the fine fraction (0.25–0.50 mm diameter) of expanded perlite. This difference in water holding ...

Expanded perlite can be manufactured to weigh as little as 2 pounds per cubic foot (32kg/m 3) making it adaptable for numerous applications. Since perlite is a form of natural glass, it is classified as chemically inert and has a pH of approximately 7. Typical Physical Characterictics of Perlite

Perlite also improves the bonding properties and provides greater uniformity. Cavity and Block-fill Perlite. There are countless reasons why nearly 50% of manufactured expanded perlite is used as a construction filler. Some of the reasons include high insulating qualities, light weight and its adaptability.

Perlite is a naturally occurring volcanic rock formed from siliceous lava or ash. Due to rapid cooling, the lava or ash solidifies into a glass-like rock. Over tens of thousands of years, surface and ground water infiltrates the rock and becomes trapped in the glass structure. When heated at temperatures from 750 to 1,250°C, perlite expands ...
