Improving Quality of Eco-Friendly Mortar using Blast Furnace Slag and Recycled Aggregate Depending on Replacement Ratio of Desulfurized Gypsum

고로슬래그 미분말과 순환잔골재를 사용하는 친환경 모르타르에 탈황석고에 의한 품질향상

The aim of this research is to contribute on investment of less cement mortar or concrete in normal strength range using additional hydration of BS with stimulating effect of FGD and OPC based on the previous research result of the BS and RFA using cement mortar. As a test, the composition for normal strength range of mortar was evaluated with 0, 10, and 20 % of FDA and 0, 20 % of OPC replacement.
