In this research, sludge was added in the brick manufacturing to reduce the clay usage and examined the plasticity, compressive strength, surface absorption and the quality of the brick with step by step addition of sludge in the raw material, and compare the results with the brick quality standard rules and regulations whether the quality is satisfaction able or not. We examined possibility of recycling waterworks sludge by combining clay, kaolin, and silica as a block. The compressive strength was observed 361.1kgf/㎠ when brick was manufactured with 75% clay and sludge 5% and 20% silica which compete the 1st grade brick standard. The compressive strength was observed 349.9kgf/㎠ when 70% clay, 10% sludge and 20% silica, and 317.3kgf/㎠ was observed when 65% clay, 15% sludge and 20% silica was added, which satisfy the brick quality standard. Absorption of the brick manufactured by the addition 20% silica of 5%, 10% 15% sludge was observed 5%, 7.65%, and 8.92% respectively, satisfying the brick quality standard of grade. Conclusively, absorption and compressive strength with the addition of proper amount of sludge which satisfies the brick quality standard was observed 10 ~ 15%.
