시멘트 분쇄공정별 물성에 관한 기초적 연구 = A Fundamental Study on the Properties of Cement Collected at Different Process Line

다국어 초록 (Multilingual Abstract)

This paper is to investigate the chemical composition and physical properties of cements collected at different crushing process line of ordinary portland cement to verify the possibility for producing special purpose cement based on the particle distribution technique. According to test results, six different cement samples with different blaine were gathered. loss on ignition and chemical composition of cements gathered were satisfied with KS L 5201. Cement collected at line 5 had the lowest blaine value while cement at line 4 had the highest blaine value. The coarser the cement particle is, the larger the fluidity of cement is. The compressive strength of cement was highly affected by the blaine value of cement. It is confirmed that the use of cement produced by the process of particle distribution control maybe applied for special purpose cement with out modification of chemical composition.
