공극수 추출방법에 따른 시멘트 페이스트의 수화도와 공극 특성 분석

Evaluation of different methods to remove pore water in an early age cement paste for the degree of hydration measurement and pore structure analysis.

The analysis of microstructure is essential to understand the material behavior such as shrinkage, strength, and permeability. In this study, three different easy-to-apply specimen preparation methods for the mercury intrusion analysis were chosen, and their effectiveness in removing pore water and thus impeding further hydration was evaluated. As a result, it was found that the direct freeze-drying was the most effective among the three methods.
