| Abstract |
This study evaluated flexural and shear behaviors of high-insulation precast concrete panels utilizing artificially manufactured lightweight
aggregates derived from sewage sludge referred to as SH-panel. The key parameters investigated include the compressive strengths of the
concrete, longitudinal reinforcement ratios, insulation types, and the presence of thermal meta. The results indicated that the flexural and shear
strengths of the SH-panel specimens could be conservatively assessed using the design procedure outlined in ACI 318-19 provisions.
Furthermore, the SH-panel specimens demonstrate comparable flexural ductility when compared to conventional lightweight aggregate concrete
beams. In addition, all SH-panels satisfied the performance requirements for grade 1 strength resistance, as specified in KS F 4736 for
lightweight panels, as well as the wind load resistance criteria outlined in KDS 41 10 15 for exterior building materials with special wind
resistance. |
