Perlite concrete: a review

Abstract The thermal resistance of concrete significantly influences the energy consumption building. Consequently, with high can contribute to envelope’s efficiency. In order obtain conductivity performance required for passive house standard using principles sustainable development, it is essential analyze improvement solutions a low impact on environment. For this reason, necessary methods improving concrete’s by replacing aggregates ecological materials like perlite. Perlite common term used glassy natural volcanic rock in construction various mixtures its fire resistance, density, and acoustic properties. While processing raw perlite (cutting, grinding, fractionation sizes), large amounts powder are collected stored as waste. Currently, only limited waste recycled industry, which urges efficient use limit There studies about from point view structural strength. However, results contradictory, influenced size particles replacement levels mixture. This article aims present current state knowledge regarding characteristics mixture between
