This study was carried out to evaluate the significance of utilizing industrial waste such as bottom as potential material to production of sand brick with developing the brick containing Bottom Ash. From the result obtained of this study, conclusions can be drawn as the following:

1. The result of this research proves that bottom ash brick is suitable to be used in the industry as it passed the strength and density requirement besides being advantageous due to its lightweight characteristic.

2. Bottom ash cement brick has higher water absorption and porosity than sand cement brick and it effect the compressive strength of brick and water absorption and porosity of brick are decreased uniformly as the age of testing is getting longer.

3. It is found that composite strength system gave positive effect to the elasticity and density value of brick containing Bottom Ash and elasticity and density value of bottom ash brick reduces when the sand is replaced with bottom ash.
