 시멘트 클린커 생성과정에 미치는 Potassium의 영향 II. 불안정 알칼리 생성 인자 서일영, 최상홀 한양대학교 무기재료공학과 Influence of Potassium on the Cement Clinker Formation : II. Factors of Unstable Alkali Formation ABSTRACT Effect of alkali $SO_3$ and $C_2S$ content and cooling condition of clinker on the formation of unstable alkali and cooling condition of clinker on the formation of unstable alkali was investigated. As a result alkali and $SO_3$ content of clinker were the main factors of unstable alkali formation and equation (7) in which the two factors were the variables showed a good agreement with the observed results. Water soluble alkali content of sulphate was decreased with increase of $C_2S$ content of clinker resulted by the increase of solid solution rate of alkali to clinker minerals. But change of unsatble alkali content accordint to the increase of $C_2S$ content was slight. A increasing tendency of ignition loss of clinker with increase of unstable alkali content was found.
