In this study, acid waste sludge and paper slurry ash could be recycled and used as raw materials to manufacture high-furnace sludge, light-weight bricks and blocks for high-furnace sludge. The results of the study are as follows. 1) Mixing AS 3% of weight of paper slurry ash with 100% weight for high-furnace solution was possible to obtain a hardener with a hardness of 5 or higher within 10 seconds without increasing volume. 2) Light-weight blocks manufactured from paper slurry ash and waste water sludge were immediately heated and hardened to obtain high-strength light insulation blocks. 3) By manufacturing light-weight blocks using PAN-CASTING process, good result value as light-duty insulation block was obtained through heavy metal elution test, heat-resistance test, compressive strength and thermal conductivity test. 4) Lightweight blocks with MOULD PRESS performed better than those manufactured by PAN-CASTING process, and heat conductivity in particular was also able to obtain results that were superior to those of conventional light concrete.
