Perlite an overview ScienceDirect Topics
Sterilization, Reuse, and Waste Disposal—Perlite is a sterile product as it is produced at very high temperatures Chemically, perlite is a stable material, which can last for several years (Acuña et al, 2013); its stability is not greatly affected by acids or microorganismsBeing an inert material, recycling perlite poses no environmental problemsSpecific “browncoat” plasters, such as “browning coat” plasters formulated with perlite rather than vermiculite, are generally more applicable for higher suction backgrounds such as porous aerated concrete lightweight blocks, or the older “coke/breeze” blocks, certain brick surfaces and when covering tiled surfacesVermiculite Gypsum Plasters ConcretePerlite pipes and blocks are made from expanded perlite, which is produced by heating the raw perlite material to temperatures of around 850°C Perlite is a naturally occurring, siliceous volcanic mineral that expands when heated to form tiny glass bubbles of entrapped air ˚e heating process causes moisture combined in the rock toSpeci˜cation of ASTM C610 Standard Figure Hess PerliteICMIEEPI 3 It is noted that water contents at the completion of gel formation from (gel+liquid) are approximately constant at high dilution levels (Table 4)Development of new perlite/sodium silicate composites
