最近提出了几种新的方法来快速测量饱和水泥浆体、砂浆和混凝土的液体渗透性。讨论了这些技术的相对优点，并给出了在浆体和砂浆上获得的一些最新结果。水泥浆体中的低渗透率与干燥后测得的孔径分布不一致，表明干燥后水泥浆体的孔结构发生了显著变化。
Several novel methods have recently been proposed for rapid measurement of the liquid permeability of saturated cement paste, mortar and concrete. The relative merits of the techniques are discussed, and some recent results obtained on pastes and mortars are presented. The low permeabilities seen in cement paste are inconsistent with the pore size distributions measured following drying, indicating that the pore structure is significantly changed by drying.
