Abstract
The method for extracting pore solution in hardened cement mixture by high pressure force was developed in the 1970's.
Chemical components in the pore solution are in equilibrium with the solid phase around them. Composition of the liquid phase is influenced by the properties of hydrate materials, which consist of hardened cement mixture. Liquid phase composition also changes with curing conditions and hydration. Therefore, since deterioration in concrete advances through the pore solution, the mechanisms of deterioration can be identified by examining pore solution.
We summarized the investigation of this extraction method, analytical method and application, and give some suggestions for future researches.
