Expanded Perlite 100L AUSPERL Australian Perlite

The expansion process is caused by the presence of water in the crude rock. When perlite ore is rapidly heated to above 850°c this water vaporises and causes the softened rock to expand. Tiny glass-like bubbles are produced which account for the lightweight and

Perlite Dupre Minerals

Expanded perlite is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 6mm in size. It is inorganic, inert, neutral in pH, biologically stable and has no asbestos content. It has excellent thermal insulation properties over an extremely wide temperature range from cryogenics at minus 273°C (absolute zero) up to refractory applications at over 1000°C. It also

Perlite an overview ScienceDirect Topics

Physical Characteristics Expanded perlite is very light with a particle and BD of 0.9 and 0.1 g cm −3, respectively. It is very porous, has a strong capillary action and can hold 3–4 times its weight in water. 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

Perlite Wikipedia

Expanded perlite Properties. Perlite boulders with fireweed in foreground. Perlite softens when it reaches temperatures of 850–900 °C (1,560–1,650 °F). Water trapped in the structure of the material vaporises and escapes, and this causes the expansion of the material to 7–16 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the trapped

[PDF] Effect of Expanded Perlite Aggregate Dosage on

In this paper, an experimental study was carried out in order to provide more data on the effects of expanded perlite aggregate (EPA) dosage on the compressive strength and thermophysical properties of lightweight concrete at different ages. The first part of this experimental study was devoted to the choice of the proper mixing procedure for expanded perlite concrete (EPC).

Perlite Imerys Metalcasting Additives

The production of expanded perlite is a two-stage process. The ore is firstly mined, pre-crushed, ground and graded in the processing plant, which is usually located nearby to the mine site or to the loading/shipping point. The output of such plants is a series of co-produced perlite grades (having grain sizes between 3,5 mm and 0,075 mm. Sized perlite grades are then transported either bulk

US4525388A Process for expanding and coating perlite

Expanded perlite is produced while simultaneously or substantially simultaneously coating the expanded perlite with an hydrophobic coating material by passing the expanded perlite and heated expander exhaust gases from the expansion chamber through a cooling and coating chamber provided with spray nozzles to provide a stream of atomized coating material onto the expanded perlite, while
