Abstract—This study performed investigation of physical and mechanical properties of hollow brick design with sago husk as filler and its combination with 10% bottom ash. As previous works showed excellent result in those properties, and 5.6 MPa gap for compressive strength with the minimum requirement, it was expected that hollow design of bricks still provided good results. Six models of hollow bricks were developed by considering stress concentration factor that might affect compressive strength. Those models were examined with three composition of sago husk filler, i.e. 1.1%, 2.2% and 2.5%. Similar method of production was conducted. It can be concluded from the result that all developed models could be used for both structural and non-structural element of wall housing. The bulk density varied from 1.3 to 1.8 kg/cm3 and the IRA was approximately 0.18%. Therefore, utilization of hollow brick design for building will provide better performance in terms of strength and building weight.

Index Terms—Bottom ash-hollow brick, sago husk, density, humidity, compressive strength, stress concentration.
