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.

ELECTRORHEOLOGICAL PROPERTIES OF BIODEGRADABLE CHITOSAN/EXPANDED PERLITE COMPOSITES

Journal of the Turkish Chemical Society, Section A: Chemistry, 2016
In this study, chitosan (CS)/expanded perlite (EP) composites with different chitosan fractions (10%, 20% and 50%) were prepared by absorbing chitosan into porous networks of expanded perlite, as a new hybrid smart electrorheological (ER) material ...

Aerogel and expanded perlite incorporated lightweight cementitious composites containing crushed glass: Evaluation of the drying shrinkage and alkali-silica expansion [PDF]

Science Progress, 2022
Lightweight cementitious composite (LCC) produced by incorporating lightweight silica aerogel was explored in this study. Silica aerogel was incorporated as 60% replacement of fine aggregate (sand/crushed glass) in producing the LCC.
