Why Mineral Aggregates Work. Perlite and vermiculite are lightweight, making them valuable for this application. They each also have their own unique properties that improve gypsum plaster. Perlite. Perlite is one of nature's most versatile and efficient minerals, formed by volcanic glass.
The lower thermal conductivity of pumice concrete provides less heat loss. Hess pumice concrete has 4X the R-value of typical sand-and-gravel aggregate concrete. This significant R-value increase both slows heat transfer and eliminates or reduces moisture condensation on walls and ceilings.
Aug 11, 2008· Expanded perlite aggregate (EPA) is a heat and sound insulator, and lightweight material which ensures economical benefits in constructions. This paper investigates the properties of concrete containing EPA considering cement types (CEM II 32.5R and CEM I 42.5R), dosages (300, 350 and 400) and replacement ratios (0, 15, 30, 45 and 60).
Describing Perlite Concrete. Perlite concrete aggregate combined with Portland cement, air entraining agent, and water produces an ultra lightweight concrete that is used for insulating roof decks and lightweight floor fills, insulating structural rood decks, curtain wall systems and for a variety of permanent insulating applications.

228 A Study of Lightweight Concrete Admixed with Perlite mechanical ing. This type of concrete is known as aerated, cellular, or gas concrete. The most popular way of lightweight concrete production is by using lightweight aggregate. Such aggregates, natural or artificial, are available in many parts of the world and can
Pumice is solidified that forms from lava rich in gases. It has numerous pores in the form of bubbles and irregular cavities that absorb moisture. This lightweight stone is used to amend garden soil improving aeration and drainage while maintaining moisture levels. 3/8" x 0 sized Pumice 1/4" minus with about 20 % fines. Our pumice is horticulture grade, pH neutral, and available in 2 sizes.
Perl-ag Perlite Aggregate is a lightweight aggregate, similar to vermiculite but is white in color and is produced from a silica based volcanic glass, when heated this volcanic glass expands to form a lightweight aggregate used in concrete, plaster and as a medium for .
