The purpose of this study is to examine the effect of stabilization disposal and recycling on incinerated paper mill sludge ash as cement additives. It was investigated chemical(pH. ICP, TGA XIID) and physica](PDA. SEM) characteristics of the incineration ash. And the pozzolanic characteristics of incineration ash was applied to cement as additive to increase the compressive strength. The results were that the pH characteristic of incineration ash was strong alkalinity. the content of silica and alumina as a pozzolanic material was 50.97%. and the average particle size was 5.03)1111. respectively. When the ash contents as cement additive were varied in 0of cement weight to explore the effect of the compressive strength on the solidified cement mortar, the proper amount of the incineration ash substituted was about 5-1O%(wt). Therefore we found thal using the incineration ash as cement additive obtains the recycling of waste material. the stabilization disposal. the reduction of waste disposal expense, and the protection of environmental problem. too.
