Lightweight dry mix shotcrete was mixed with an expanded perlite aggregate (EPA) and the thermal and mechanical properties of the resulting samples were tested. A number of EPA/sand ratios were used to produce the samples. The TPS instrument was used to measure the thermal ...
Perlite was added to mortar in order to determine if the resulting composite was more thermally insulating than conventional shotcrete. This study was conducted to determine if shotcrete in which sand has been replaced by perlite can potentially be used as thermal insulation for underground ...
The shotcrete technique is a method used to pneumatically spray concrete at mine openings to provide insulative working environments. This study tested the thermal conductivity of Expanded Perlite Aggregate (EPA) to determine its effectiveness as an insulative material in conjunction with concrete for mining applications. ...
