Research Summary: Presently, chicken eggshell (ES) and palm oil fuel ash (POFA) which from aviculture and agricultural waste can be found easily in Sarawak. As known, ES and POFA are available wastage from food industry and palm oil mills, respectively. Both of these wastage are attributed to negative impact especially to environmental problems. To solve aforementioned problem, ES and POFA are proposed to use as potential hybrid filler as concrete supplementary. Previous studies have been investigated that the potential use of natural filler (NF) from ES wastes. Egg shell is popular to be used as bio-filler in materials especially in plastics and polymers. Based on its unique characteristics, the potential use of ES as a natural filler prepared from food waste incorporated with agricultural waste of palm oil fuel ash (POFA) in concrete composite can be produced to the required properties. The properties include physical and mechanical properties of the material. The studies have been shown that egg shell able to replace up to 75% of commercial CaCO3 as new bio-filler into concrete composite. Furthermore study of ES has been proved that it performed better than all different types of particle size of CaCO3 fillers used in previous studies. The POFA contains silicon dioxide which is the most essential substance contains up to 40%. According to the previous study, the fineness and percentage of cement replacement, POFA as cement replacement enables longer initial and final setting times. Sata et al. reported that replacing POFA, as cement of up to 30% can produce high strength concrete of about 86 MPa. This study mainly focus on experimental work in laboratory to observe the properties of ES-POFA hybrid filler as concrete supplementary. Additionally, the theoretical and design procedures of the materials will be developed and established. The ES-POFA hybrid concrete can be potentially applied for green structure. In the construction industry, the findings from the study will contribute to the development of new intelligent materials for innovative structural systems.
