Cement stabilized compressed laterite bricks were tested. The compressive strength of lateritic soil based materials were determined. The objective of this paper is to determine the effect(s) of addition of cement and wood ash to lateritic soil brick on the compressive strength using four soil samples. The findings showed positive effect of the additives of cement and wood ash on increasing the compressive strength of the stabilized laterite bricks. The study showed that the optimum value for water absorption of wood ash stabilisation is at 10% C with 5% WA (19.09%) replacement and 15% C with 10% SD. The compressive strength of the different samples measured showed increase in the failure point of the brick with increase in percentage of cement and wood ash.
