Exmination of Rheological Properties on Cement Paste of High-Blaine Blast Furnace Slag Fineness

고미분말 고로슬래그의 치환율 변화에 따른 시멘트 페이스트의 레올로지 성질 검토

Recently, high fluidity concrete is becoming more prevalent. High fluidity concrete uses admixture or thickener in order to prevent separation of materials due to increased fluidity, and, especially, BS is becoming more use for reduced heat of hydration and improved long-term strength. This study examined the effect of BS on fluidity of cement paste from a rheological viewpoint. As for BS types, materials equivalent to 1 types of KS F 2563 and the cement mass was substituted by 20, 40, 60, 80%.
