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 conductivity of the samples after 28 days, and values revealed that the thermal conductivity of the samples decreased with the amount of EPA added. The splitting ...
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. A Thermal Constants Analyser TPS measured the thermal conductivity of the EPA composites using the transient plane source (TPS) method. Results showed that the addition ...
