Visually, perlite looks like sand or crushed stone (depending on the size of the fractions), white or slightly gray in color, and has no odor. Perlite is used in agriculture, metallurgy, medicine, energy, construction, etc. Depending on the area of application and the size of its particles, perlite is produced in the following most common varieties: construction perlite (fraction 0.16...1.25 mm); agroperlite (granules size 1...5 mm); filterperlite (granule size 0...0.16 mm). In the construction industry, perlite is mainly used as a thermal insulation material (60% of total use). Perlite is used as a filler for the production of lightweight concrete and mortars. Based on it, perlite blocks and bricks for laying walls, and slabs for finishing residential premises are made. In Ukraine, perlite is produced with a density of 75, 100, 150, 200 kg/m3.
