| Popis: | International audience; Given the low mechanical strength, hemp concrete cannot therefore be used as a load bearing material. Hemp concrete principal weakness point is the strength but the lack of information concerning the durability performance of this material can also be an explanation for the professional's reluctance to use bio-based concrete. This study focused on the effects of aggregate treatments, linseed oil and two different binders. The mechanicals performance such as the compressive strength at 7, 14 and 28 days were done. The results shows that with higher density treated samples get a higher strength in compression.. Then hydraulic performance was tested with the capillarity test and highlighted the great decrease of sorption coefficient on treated samples. Finally the durability performance tests included the full water immersion test, and the carbonation test in accelerated chamber. Weathering results are better for treated sample compared to none-treated, which are less absorbent and less destructive for specimens. Treated samples carbonated quicker than no treated ones. |
