Abstract

Extrusion technique was used for producing arched lightweight cementitious composites panels (LCCPs) to protect thermal leakage of pipe with high temperature. The results indicated that with 40. 0 wt% addition of expanded perlite (EP) with mean size of 40 µm, thermal conductivity of the LCCPs can be greatly reduced by 78.4% without scarifying too much of mechanical strength, which ensured that two arched LCCPs can be riveted together as a cover to protect circular pipelines from thermal leakage. More attractively, compared with casting method, the novel LCCPs by extrusion showed a higher automatic and massive production, lower cost and better sustainability, which can be served as a good candidate of thermal insulating materials for piping system.
