Nowadays a modern building must be energy efficient, i.e. distinguished by extremely low energy consumption. The building must be built according to the principles of sustainability, considering how it can be maximally friendly to the environment, and its life cycle should comply with the principles of the circular economy. Buildings with constructions made from natural origin materials are being built more and more in Lithuania. Such materials include fibrous hemp. The study presents the results of research on the properties of hemp shiv concrete made with binders of different compositions. The calcitic lime, composite portland cement, organic sapropel and mixtures of these materials were used as binding material for the research. Hemp shives are used for concrete fillers. The tests determined the compressive strength of hemp-shiv concrete, and the thermal conductivity of the concrete was tested under laboratory conditions. The research was performed based on standard methods and equipment.
