영어 초록
First, a purified sludge was calcined at various temperatures viz. 800, 900, 1000, 1100 and 1200˚C per hour. Subsequently 100 wt% of ware from Geryong mountain was mixed with 5~25 wt% of a purified sludge. Then the ware was treated at 1250˚C in an electric kiln to test a bending strength. The physicochemical property of the prepared ware was characterized by XRD, Raman and SEM analysis. Among the different percentage, 25 wt% of a ware in a purified sludge calcined at 1000˚C showed 689 kg/cm2 strength. Also the purified sludge calcined at 1000˚C was adequate physical properties than the other composites. Further to enhance the physical strength, 3 wt% TiO2 (a mineralizer) was added into the ware and the strength was increased up to 731 kg/cm2. The composites exhibit absorption and porosity rates of 0.17% and 0.39% respectively.
