Cockle shell is one of the marine organisms that easily found in Malaysia. This invertebrate type of animal lived by depending on their shell that contains of high calcium carbonate which makes it so tough and can be explore for further application. In this study, a ceramic material was fabricated from cockle shell and sucrose as a binder. The cockle shell was crushed and milled into small size at around 160 μm -200 μm. The cockle shell powder then was mixed and compacted with sucrose binder by ratio of 10, 20, and 30 wt%. The drying process was carried out in 2 methods which are heating at 150°C for one hour and normal drying at room temperature for 1 day. The effect of binder percentage and drying method on flexural properties, density and porosity of ceramic were investigated. Flexural test result shows that the samples with oven drying produced better resistance compared with samples dried at room temperature and the highest strength was obtained by sample with 20wt% sucrose dried in oven. The sample with 20wt% sucrose dried in oven also has the highest values of density. 20 wt% sucrose binder has higher ultimate strength and higher maximum force. The comparisons of sample morphology were determined by scanning electron morphology (SEM).
