Mercury intrusion porosimetry (MIP) is a widely used technique for characterizing the distribution of pore sizes in cement-based materials. It is a simple and quick indirect technique, but it has limitations when applied to materials that have irregular pore geometry. The relationship between MIP results and the actual pore distribution and connectivity can be better understood with the use of image analysis. This paper discusses the use of MIP to describe the pore structure of cements and the efforts to validate the technique with microscopy. In particular, a study using molten Wood's metal as an alternate intrusion liquid that is solid in the pores at room temperature and can be examined by scanning electron microscopy will be presented. Results of the image analysis and the intrusion behavior of Portland cement mortars will be discussed. Copyright 1999 Academic Press.
压汞法（MIP）是一种广泛用于表征水泥基材料孔径分布的技术。它是一种简单快速的间接技术，但应用于具有不规则孔隙几何形状的材料时存在局限性。通过图像分析可以更好地理解MIP结果与实际孔隙分布和连通性之间的关系。本文讨论了使用MIP描述水泥孔隙结构以及用显微镜验证该技术的努力。特别是，将介绍一项使用熔融伍德合金作为替代侵入液体的研究，该合金在室温下在孔隙中呈固态，可通过扫描电子显微镜进行检查。将讨论波特兰水泥砂浆的图像分析结果和侵入行为。版权所有1999年学术出版社。
