Abstract

Green building concept is developing to become an important technology in construction industry. One of the way to achieve the green building concept is by using nature resources such as seashell. This study focus on the use of green mussel shell ash (perna veridis) as admixture in concrete. This study was carried out to determine the optimum percentage of green mussel ash and the compressive strength of concrete that used mussel shell ash as admixture in concrete. Furthermore, setting time and specific gravity test was carried out to study the physical properties both the mussel shell ash and Portland cement. Then, for mechanical properties of this study was determining the compressive strength and density of the concrete. The percentage of admixture that had been used in this study were 0% (P0), 2% (P2), 4% (P4), 6% (P6) and 8% (P8). The concrete samples were prepared in the 100mm x 100mm x 100mm cube. In this study, the total of 60 cube were prepared and had been curing in water for 7 and 28 days. The grade of the concrete was 30 MPa at 28 days curing. Result of physical properties showed the specific gravity of the cement is lower than mussel shell ash which is 2.8 and 2.9 respectively. Next for setting time result mussel shell absorption faster than cement Portland. Then, for mechanical properties for this research, it can be concluded that the optimum percentage of mussel shell ash as the additive in the concrete was 2%. Thus, the high calcium content in the mussel shells will provide additional calcium to the concrete mixture and it will produce better concrete compare to normal concrete
