고로 슬래그 분말의 입도에 따른 충전률과 유동특성
Rheological Properties and Particle Packing of Different Sized Blast-furnace Slag Powder
초록
시멘트 결합재로 널리 사용되어지고 있는 고로 수쇄 슬래그 분말을 각종 분쇄기를 사용하여 입도별로 분쇄하고, 이를 혼합하여 충전률과 유동특성을 비교 분석하였으며, 입도분포 또한 비교분석 하였다. 충전률과 유동특성은 비례의 경향이 크게 나타났고, 입도분포가 넓을수록 유동특성은 높았다.
The different sized slag powder, which have been used widely as a cement binder, was obtained by using 3 kind of mills. Two kinds of slag powder with different size was mixed and then investigated the relationship between the rheological properties and the particle packing ratio or particle distribution. It was found that the rheological properties of two mixed slag powder was proportional to the particle packing ratio of it. And the paste flowability of the mixed slag powder with wide particle distribution was very good.
