混凝土孔隙流體抽取儀
孔隙流體分析可用于了解混凝土的耐久性問題,孔隙液體通過高壓擠壓獲取,耐久性與堿、氯化物粘合物有關,與鈣礬石形成的延遲有關。可抽取硬化達9個月以上的混凝土孔隙液體?! ?/span>
混凝土孔隙流體抽取儀描述
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(混凝土孔隙流體抽取儀).
Up to 1 000 MPa
Allows extraction of 9 months aged samples
Easy extraction of the piston after use
