混凝土孔隙流体抽取仪
请通过我们伯英科技联系我们!
孔隙流体分析可用于了解混凝土的耐久性问题,孔隙液体通过高压挤压获取,耐久性与碱、氯化物粘合物有关,与钙矾石形成的延迟有关。可抽取硬化达9个月以上的混凝土孔隙液体。
混凝土孔隙流体抽取仪描述
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(混凝土孔隙流体抽取仪).
Up to 1 000 MPa
Allows extraction of 9 months aged samples
Easy extraction of the piston after use
