장기재령에 따른 고로슬래그를 사용한 모르타르의 강도특성 = The Strength Characteristics of Mortar Using Blast-Furnace Slag for Long Ages

다국어 초록 (Multilingual Abstract)

The purpose of this study is to examine strength characteristics of mortar using blast-furnace slag for long ages, 365days.
In this paper, the mortar replaced by varying fineness and content of blast-fumace slag was investigated through the flow value and the compressive strength. This experimental study was acquired following results by the material tests of fresh and hardened mortar proportioned standard sand and natural sand, mixing proportion of 1:2, 1:3, 1:5, slag fineness of 4500, 5500, 6500㎠/g, water binder ratio 40, 45, 50, 55, 60% and replacement rate of 0, 15, 30, 45%.
The results are as follows
1. Blast-furnace slag increased somewhat higher flow value.
2. The higher fineness of slag developed the higher compressive strength.
3. The highest compressive strength appeared at 30% replacement rate.
4. Slightly higher compressive strength appeared at standard sand mortar rather than at river sand mortar.
