Acquisition of a Mercury Intrusion Porosimeter

购买了汞侵入孔隙度计。该仪器通过在压力下将汞压入材料中来测量多孔或颗粒材料的孔隙大小。由于汞不会弄湿表面，所以压力和孔隙大小之间有一个简单的关系，可以用来校准仪器。孔隙度计将用于研究混凝土的孔隙大小，并将孔隙大小与耐久性联系起来。另一个项目将把水泥浆的孔径与强度联系起来。研究将进行孔隙大小与砖，煤，土壤和多孔聚合物的性质之间的关系。

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.
