지오폴리머 생산을 위한 알루미늄 규산염 원료물질로서의 4가지 한국석탄재의 적정성

Abstract

Briquette ash and three coal ashes collected from power stations in Korea were examined. The contenr of glass and crystalline phases present in each ash was determined by XRF. Briquette ash showed a wide range from 3.39 to 15.35 of reactive Si:Al ratio due to the crystallite-size parameter dependence of dehydroxylated miscovite and dehydroxylated pyrophyllite on the refinement results.tive Si:Al ratio due to the crystallite-size parameter dependence of dehydroxylated miscovite and dehydroxylated pyrophyllite on the refinement results.
