고로슬래그 굵은 골재를 사용한 슬래그 콘크리트에 대한 강도특성과 동결 융해시험에 의한 내구성 관계를 시험해서 슬래그 콘크리트의 실용화를 위한 여러 물리적인 값을 규명하였다.
또 하천자갈을 쓴 보통 콘크리트에 대해서도 상기의 시험을 통하여 비교하였으며 감수제로는 AE 감수제나 고성능 감수제를 쓰고 또한 콘크리트의 내구성과 밀접한 관계가 있는 경화콘크리트의 기포 시스템의 공기량, 공극의 비표면적이나 간격계수등도 현미경으로 측정하여 이들의 상관관계도 알아보았다.

Blastfurnace Slag is a by product in the process of pig iron production in the finery. Presently annual product of blastfurnace in this country comes to 3 million tons.
In this study, the strength characteristic and the durability relation ship of the freezing and thawing in slag concrete which is mixed with coarse aggregate of blastfurnace slag are examined, and as the testing result, the parameters of the physical property are established for the practical use. And with a view to making a comparison above various parameters between slag concrete and normal concrete which is mixed with river gravel, AE concrete and high strength concrete which is compounded with superplasticizer are studied.
Specially air of air-bubble system, specific surface of the void, and the parameters of the void in the hardening concrete which is closely related with the durability of concrete are measured by the microscope and interrelation between these values are suggested.
