Experimental Study on Hygrothermal Performance and Durability of Sandwich Wall Panels Made of Fiber Reinforced AAC and PU Foam Insulation
This paper evaluates a novel prefabricated sandwich wall element comprising a 200 mm load-bearing fiber-reinforced autoclaved aerated concrete (FRAAC) layer, a 150 mm polyurethane (PU) foam infill, and a 100 mm exterior FRAAC layer, without additional mechanical connections. The study involves measuring hygrothermal material properties, conducting climate chamber tests for performance assessment and model validation. Moisture profiles of FRAAC outer core was evaluated gravimetrically and impact of freeze-thaw cycling for the structure was evaluated with pull-off tests. Results indicate that covering the FRAAC sandwich with façade render system provides protection during rain events, but slows the dry out process of the wall. The hygrothermal model shows promise for future wall system improvements and various climatic scenarios. Although the FRAAC-PU foam connection remained strong during the study, potential aging effects of polyurethane must be researched in the future.
