A solidification composites pulverized coal ash and fluidized-bed boiler coal ash
The present invention relates to a solidification composition comprising fluidized bed boiler coal ash and pulverized coal ash. The solidification composition comprises: (1) 20 to 65 wt% of pulverized coal ash containing 5 to 20 wt% of Na_2SO_4; (2) 20 to 50 wt% of fluidized bed boiler coal ash containing 15 wt% or more of CaO, including free-CaO; (3) 5 to 15 wt% of blast furnace slag; (4) 3 to 15 wt% of calcium ferrite; and (5) 1 to 5 wt% of superabsorbent polymer.
본 발명은 (1) Na2SO4가 5 내지 20 중량%로 포함된 미분탄 석탄회 20 내지 65 중량%; (2) free-CaO를 포함하는 CaO가 15 중량% 이상으로 포함된 유동층상 보일러 석탄회 20 내지 50 중량%; (3) 고로슬래그 5 내지 15 중량%; (4) 칼슘페라이트 3 내지 15 중량%; (5) 고흡수성 수지 1 내지 5 중량%;를 포함하는 유동층상 보일러 석탄회와 미분탄 석탄회를 포함하는 고화재 조성물에 관한 것이다.
