Sorptivity and Hydraulic Diffusivity of Coating Gypsum and Impact of Hemp Fibers Addition

Article Preview

This paper aims to provide a better understanding of the gypsum hydric behavior used as coating during imbibition in liquid water. Firstly, we want to describe hydric transfer by determining sorptivity and hydraulic diffusivity of coating gypsum. Secondly, we evaluate the impact of the hemp fibers addition on hydric parameters. Experimentally, hydraulic diffusivity will be obtained by an overall measure of the moisture content (mc) in a defined sample volume, and the sorptivity describes capacity absorption. Through numerical simulation, hydraulic diffusivity will be determined by a local measure of the mc.
