A Fundamental Study on the Effect of Anti-Freezing Agent of Concrete

콘크리트용 내한제의 효과에 관한 기초적 연구

If the concrete is exposed below freezing point of the outer temperature before hardened, the quality of the concrete will be lowered after hardened. Anti-freezing agent which doesn't corrode the steel bar and doesn't generate the alkali-aggregate reaction by noncholride recently developed in Japan and Northern Europe. But the effects of these agents are rarely known. Therefore, this study is desigend for analyzing the freezing properties at the condition of solution of solution and cement paste. And this study aims to present the reference data for practical use of the concrete works using anti-freezing agent.
