CaCO3와 Al2O3를 이용한 CaO-Al2O3계 클링커 합성
Synthesis of CaO-Al2O3 System Clinker Using CaCO3 and Al2O3
초록
This paper presents the synthesis results of CaO-Al2O3 system clinker using the CaCO3 and the Al2O3 according to the synthesis methods dependent on the temperature. The purpose of this study is the formation of the CaO-Al2O3 system clinker containing high ratio of CaO·2Al2O3 (CA2). The maximum sintering temperature for the synthesis of CaO-Al2O3 compounds was 1250℃, 1300℃ and 1400℃. The CaO-Al2O3 compounds was sintered at the maximum sintering temperature for three hours. After sintering, the compounds was analyzed using X-ray diffraction method. The 12CaO·7Al2O3 (C12A7) and CaO·Al2O3 (CA) increased as elevating the maximum sintering temperature whereas the CA2 decreased. Especially, at the 1250℃ of maximum sintering temperature, the un-reacted CaO and Al2O3 was identified.
