Abstract: This paper investigated the effects of aggregate treated with linseed oil and two types of binders (calcic lime and Prompt Natural Cement binder-Vicat). The particle distribution, the absorption of particles, the capillarity absorption of hemp concrete and the compressive strength at 7, 14 and 28 days were determined. The results showed that with higher density treated samples get a higher compressive strength. In addition, hydraulic performance was tested with the capillarity test and highlighted the great decrease of sorption coefficient on treated samples. Concerning the autogenous shrinkage, the results of treated samples shrinkage were higher than no-treated ones. Finally, the durability performance test included the full water immersion showed that treated samples with linseed oil are better compared to none-treated. These treated samples absorbed less water, therefore less degradation and softening of the specimens.
