Abstract

Mixture of natural hydraulic lime (NHL) and limestone powder (LP) could promote formation ofhydration product because the limestone powder plays an important role as filler and binder in hardened mortar.Therefore, in the present study, the paste and mortar specimens of NHL-BFS (blast furnace slag)-LP were preparedto investigate hydration behavior and the effect of hydration on physical property. The results indicate that ettringiteand calcium silicate were observed within 1 day hydration by adding limestone powder, and that compressivestrength increased and setting time was shorten with increasing the amount of limestone powder. However, thestrength decreased with increasing further the amount to more than 30%.

천연수경성석회와 석회석 미분말을 혼합하여 사용할 경우 수화초기 수화물의 생성을 촉진하며, 석회석미분말 입자 자체가가 경화체 내에서 binder 및 filler로서의 역할을 하기 때문에 응결 뿐 만아니라 전체적인경화체의 내구성을 향상시킬 수 있다. 따라서 본 연구에서는 NHL-BFS-LP 3성분계 페이스트 및 모르타르를제작하여 수화특성 및 이에 따른 물리적 특성 향상의 연관성에 대하여 조사하고자 하였다. 실험결과, 석회석미분말 혼합에 따라 수화초기인 재령 1일부터 ettringite와 calcium silicate 계 수화물이 생성된 것을 알 수 있었으며, 석회석 미분말 혼합량이 증가함에 따라 압축강도가 향상되며 응결시간이 단축되는 것을 확인하였다. 다만,석회석 미분말 혼합량이 30% 이상일 경우 압축강도가 감소하는 경향성을 나타내었다.
