Effect of Partial Replacement with Cement and Recycled Fine Aggregate on Properties of Blast Furance Slag-Based Mortar

고로슬래그 미분말 모르터에 시멘트 및 순환잔골재 치환율 변화에 따른 품질특성

This study investigates the effect of partial replacement with cement on the properties of blast furnace slag-based mortar. Recycled fine aggregate with various contents was used to activate the hydration of blast furnace slag in the mortar and compared its effect on strength development. Results showed that increasing cement and recycled fine aggregate increased the strength of mortar specimens. However, this study found that the mortar made with partial replacement of river sand with recycled fine aggregate of 20% developed a similar strength to the strength that cement with 10% can achieved.
