OpiCAD

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
