Lightweight Reactive Powder Concrete Containing Expanded Perlite [PDF]
Materials, 2021 This paper presents the test results of the lightweight concrete properties obtained by adding expanded perlite (EP) to an RPC mix in quantities from 30% to 60% by volume of the concrete mix. It has been shown that in these cases it is possible to obtain concrete containing 30% by volume with density of approximately 1900 kg/m3 and the compressive ...

Hydrophobic coating of expanded perlite particles by plasma polymerization
Chemical Engineering Journal, 2016 Abstract In this study, an RF plasma discharge was employed to deposit thin poly(hexafluorobutyl acrylate) (PHFBA) polymeric films on expanded perlite. A rotating plasma reactor was used to provide effective agitation and mixing of the particles during the depositions.

Influence of zeolitized perlite on blended cement properties [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2016 Perlite is the mineral of volcanic origin. Expanded perlite has good heat insulation and sound absorption properties. It is light, resistant to fire, moisture and micro-organisms, harmless to health. However, due to the presence of hyaline phase,
