混凝土孔隙流体抽取仪

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。　　

Concrete pore fluid extraction

混凝土孔隙流体抽取仪描述

Description

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）.

混凝土孔隙流体抽取仪技术指标：

Characteristics

• Up to 1 000 MPa

• Allows extraction of 9 months aged samples

• Easy extraction of the piston after use
