| dc.description.abstract | Oil palm shell lightweight concrete (OPSLC) is a lightweight aggregate concrete that used oil palm shell (OPS) as coarse aggregate. Produced from the oil palm industry, OPS is one of the solid waste material and has the capability to be used as concrete material. The application of OPSLC is primarily as a structural lightweight concrete in building components. This research explores the potential of using OPSLC as insulation concrete with load bearing strength for external wall panel in construction especially for domestic houses. Experimental and analytical studies were conducted to develop OPSLC load bearing wall with insulation concrete capacity. In order to achieve the insulation lightweight concrete requirement, 15 trial mix designs were developed to examine the characteristic of OPSLC as insulation lightweight concrete with load bearing strength. Then, three optimum designs (OPS: volume fraction of 30%, 32% and 34%) that achieved both requirements were selected and incorporated with OPS of three different shapes. Thus, nine mix designs were examined in terms of engineering, durability and thermal properties in long term exposure to three different curing series environments. Based on the observation for one year performance, OPSLC is found to have the capability as external load bearing wall in domestic terrace houses. To confirm this, three prototypes of OPSLC wall panel were made based on analytical assessment study of the all mix designs. Then, the OPSLC wall panel prototypes were tested on compression load to investigate the structural performance. To evaluate the OPSLC performance at elevated temperature, an OPSLC wall panel prototype was selected for a two-hour fire resistance test. The result indicates that OPSLC has greater thermal insulation performance compared to conventional building materials. The unexposed wall surface only recorded a temperature of 63°C after exposure to fire for two hours. The value is extremely lower than those of conventional building materials. The result on structural performance of OPSLC for external wall panel indicates that the panel has sufficient load carrying capacity to be used in two-storey terrace houses | en_US |
