摘要

The development of new low-environmental impact materials is part of sustainable development objectives and offers an interesting alternative to promote building hygrothermal comfort. Raw earth combined with biomass-derived materials is currently gaining strong attention today as they are low-environmental impact materials that also contribute significantly to improving the building hygrothermal performance and comfort. This study aims to develop new raw earth/hemp composites with low hemp shiv content to improve their hygrothermal properties when used as sustainable building materials. The hygrothermal properties of raw earth composites were analyzed including moisture buffer value, water vapor permeability, moisture sorption isotherms, and thermal conductivity. The mechanical properties were also investigated. The moisture buffer capacity result is increased with the hemp shiv content and it exhibits an “excellent” category, from 2.65 g/(m2%RH) for raw earth without hemp shiv to 3.16 g/(m2%RH) for the raw earth mixed with 10% hemp shiv. The thermal conductivity shows a significant decrease from 0.89 (Wm-1.K-1) for the SP0% sample to 0.245 (W/m.k) for the SP10% sample. This tendency clearly indicates the excellent insulating ability of hemp shiv.
