Abstract

This paper presents of an investigation conducted the structural performance of oil palm shell lightweight aggregate concrete (OPSLAC) wall panel. Load-deflection characteristic on OPSLAC wall panel was conducted. Further, the effect of Stress-strain relationship and buckling effect on compression load was investigated. The variable selected are size of oil palm shell (OPS). Three wall panel specimens were prepared, and tests on compression load were conducted. The load-deflection result showed the changing on OPS shape used. The convex of OPS influence the bond within aggregate and cement paste. Further, the increasing of compression load is related to the formation and growth of micro cracks. As ultimate strength is approached, increased load and bulk paste micro cracks join to form continuous cracks parallel to the direction of loading on stress-stain curve. After 70% from the ultimate loading, the extent of cracking is so great that OPSLC cannot support additional load.
