Hemp Shives as a Raw Material for the Production of Particleboards. [PDF]
Polymers (Basel), 2022 Increased demand for wood affects its price and thus contributes to the growing interest in raw materials that can be used as a partial or total substitute for wood in the production of particleboard. One of the raw materials for the production of particleboard can be Cannabis sativa or, more precisely, hemp shives.

Influence of Pozzolans and Hemp Shives on the Properties of Non-Autoclaved Foamed Concrete. [PDF]
Materials (Basel), 2023 In this study, new foam concretes incorporating hemp shives without the use of autoclaving have been developed and studied. Several protocols and parameters were investigated. Firstly, the influence of the addition of pozzolanic additives on the resulting density, mechanical behaviour and thermal conductivity was examined.

Effect of Hemp Shive Granulometry on the Thermal Conductivity of Hemp-Lime Composites. [PDF]
Materials (Basel)This study investigates the effect of hemp shive granulometry on the thermal conductivity and microstructure of hemp–lime composites. Three distinct particle size fractions—fine, medium, and coarse—were characterized using high-resolution image analysis to determine geometric parameters such as Feret diameters, circularity, and elongation.
