Acquisition of a Mercury Intrusion Porosimeter

购买了一台压汞孔隙度计。该仪器用于测量多孔或颗粒状材料的孔径，方法是在压力下将汞压入材料中。因为水银不会弄湿表面，所以压力和孔径之间有一个简单的关系，可以用来校准仪器。孔隙仪将被用来研究混凝土中的孔径，并将孔径与耐久性联系起来。另一个项目将把水泥浆体的孔径与强度联系起来。将开展研究，将孔径与砖、煤、土壤和多孔聚合物的特性相关联。

A mercury intrusion porosimeter is purchased. The instrument is used to measure pore sizes in porous or granular materials by forcing mercury under pressure into the material. Since mercury does not wet the surfaces, there is a simple relationship between pressure and pore sizes which can be used to calibrate the instrument. The porosimeter will be used to study pore size in concrete and to relate the pore size to durability. Another project will relate the pore size of cement pastes with strength. Research will be carried out correlating pore size with properties of bricks, coal, soils, and porous polymers.
