WebPermeation properties of self-compaction concrete. Wenzhong Zhu, in Self-Compacting Concrete: Materials, Properties and Applications, 2024. 5.1 Introduction. Permeation properties, also often referred to as transport properties, which include capillary absorption, permeability and diffusivity, etc., have been widely used to quantify durability … WebThis reaction provides a way of estimating the true membrane permeability to a highly permeant weak acid and also a way of estimating the thickness of the unstirred layers. The second chemical reaction, the dissociation of a weak acid, HA ⇄ H + + A - , can be used to show how the presence or absence of buffers in the unstirred layers controls ...
