Abstract. The use of thermal energy storage composite materials allows passive cooling and heating in buildings, yielding substantial energy savings. The purpose of this study is to develop and test a new phase change material (PCM) composite by loading expanded perlite (EP) with paraffin (RT27) to form plaster composites.
Results obtained by Sun and Wang for PCM composite based on paraffin and expanded perlite exhibited lower values, even when compared to P24 plaster with the highest …
Building Materials WATERPROOF FINISH WATERPROOF FINISH A cement based waterproof finishing plaster, reinforced with acrylic copolymers and microfibers for interior and exterior surfaces, with low water absorption. Suitable for application as a finishing plaster over conventional renderings, as well as Thermocem or Thermocem T2.
These products include ceiling tiles, pipe insulation, roofing board and fire-rated door cores, and are manufactured with a variety of binders. Perlite …
expanded perlite in building materials is the lower thermal conductivity and heat transfer caused by perlite pores (air) [10,20–23], affecting the re behaviour of plasters. Besides,...
Results obtained by Sun and Wang for PCM composite based on paraffin and expanded perlite exhibited lower values, even when compared to P24 plaster with the highest FSCM dosage. They found that 30% of incorporated paraffin/expanded perlite composite exhibited a decrease in compressive strength of more than about 25%.
Perlite Uses and Applications as a Construction Filler Nearly 50% of expanded perlite worldwide is used by the construction industry, largely in part because of its versatility. Some construction applications include: …
When the perlite is heated quickly up to temperatures from 800 to 950º, it expands (expanded perlite) until 20 times its original size, forming expanded perlite with a extremely low density. It is essentially a mass of small …
Perlite cement plaster is thermal and sound insulating, fire retardant, and extremely lightweight—weighing approximately 60% less than ordinary sand plaster. Perlite …
For expanded perlite end-use categories are concrete aggregate, fillers, filter aid, formed products, horticultural aggregate, laundries, low-temperature insulation, masonry and cavity-fill insulation, plaster aggregate, and other industrial uses. The apparent consumption category applies to processed crude perlite and is not the apparent ...
Perlite Plaster; Textured Coatings and Finishes; The special properties expanded perlite adds as a concrete aggregate provide the same functional value for cement-based plasters as well. They include: …
Perlite is a naturally occurring glassy volcanic rock. When heated at extreme temperatures, it pops like popcorn, expanding up to 20 times its size. The size and grade of expanded perlite determine its use. …
Expanded perlite exhibits very low thermal conductivity, low sound transmission, high fire resistance, a large surface area and controllable moisture retention and drainage. It is chemically inert, sterile, non-toxic …
Perlite is a naturally occurring glassy volcanic rock. When heated at extreme temperatures, it pops like popcorn, expanding up to 20 times its size. …
Thermal conductivity of plaster composite containing 50% wt of RT27/EP/SL/Al composite was increased by 80% and 68% at 12°C and 40°C respectively compared with the aluminum free composite.
• Perlite plaster has low linear thermal expansion compared with sand plaster at high temperatures, which greatly reduces the number and size of cracks, which permit heat and flame to penetrate through the plaster …
From the furnace the expanded per- lite goes through a cyclone separating system that re- m o ves extremely fine particles not suitable for use as c o n c r ete or plaster aggre g a t e s . The expanded perlite is then packaged in strong paper bags which hold 3 or 4 cubic feet of aggre g a t e .
Perlite's unique property is expansion in its specific volume in 35 times when heated up to softening point. ( 850 - 1150ºC). This expansion period can be reached by the help of …
Expanded Perlite offers many benefits due to its inert, fire-resistant, thermal and acoustic properties and is used in a range of industries including Oil & Gas, Construction and Horticulture to name a few. Natural Properties Ultra Light weight (low specific weight) Chemically inert Odourless Thermal insulation Environmentally friendly
Expanded perlite provides a quick, inexpensive and permanent method for insulating masonry walls. Depending upon design conditions, reductions in heat transmission of 50 percent or more can be obtained when perlite …

What is Perlite. Perlite is a volcanic rock mined in open-pit quarries. The volcanic glass, or perlite, is formed when lava (molten rock) spews out of a volcano, and cools in a rapid manner. Because of rapid cooling, water is trapped within the rock, and the lava forms into a glass-like structure. Perlite contains 2 to 5 percent water and is a ...
Transportation and storage expenses are higher because expanded perlite is voluminous. There is a double expenditure for handling and storage of the materials, first for the raw material and then for the expanded perlite. For these reasons, bulk handling is usually a more expensive method of servicing a job than using a portable furnace. 4 ...
