This study examines the applicability of Washburn’s law for predicting capillary rise in vegetal concretes, with a focus on practical applications. The findings contribute to the groundwork for service life modeling of these materials. Initial results demonstrate a strong correlation between the capillary rise predicted by Washburn’s law and experimental observations across four mixes of hemp shiv and rapeseed straw, both with and without a viscosity-modifying agent.

摘要

This study examines the applicability of Washburn’s law for predicting capillary rise in vegetal concretes, with a focus on practical applications. The findings contribute to the groundwork for service life modeling of these materials. Initial results demonstrate a strong correlation between the capillary rise predicted by Washburn’s law and experimental observations across four mixes of hemp shiv and rapeseed straw, both with and without a viscosity-modifying agent. However, discrepancies emerged during later stages of the experiments, attributed to the finite dimensions of the samples and gravitational effects.
