Concrete pore fluid extraction
Concrete has an intricate pore structure comprising pores and voids. Pore fluid analysis has shown its usefulness for the understanding of concrete durability issues related to:
- alkali binding as it affects alkali–silica reaction (ASR)
- chloride-binding as it affects reinforcement corrosion resistance
- delayed ettringite formation (DEF)
The pore solution of concrete specimen can be extracted by high-pressure squeezing. In this way, CAD Instruments developed a special steel die to achieve extraction on concrete samples, named OpiCAD.

Characteristics
Up to 1 000 MPa
Allows extraction of 9 months aged samples
Easy extraction of the piston after use
