Research on the properties of concrete with hemp shives

Abstract

Nowadays a modern building must be energy efficient, i.e. distinguished by extremely lowenergy consumption. The building must be built according to the principles of sustainabil-ity, considering how it can be maximally friendly to the environment, and its life cycleshould comply with the principles of the circular economy. Buildings with constructionsmade from natural origin materials are being built more and more in Lithuania. Such mate-rials include fibrous hemp. The study presents the results of research on the properties ofhemp shiv concrete made with binders of different compositions. The calcitic lime, compo-site portland cement, organic sapropel and mixtures of these materials were used as bindingmaterial for the research. Hemp shives are used for concrete fillers. The tests determined thecompressive strength of hemp-shiv concrete, and the thermal conductivity of the concretewas tested under laboratory conditions. The research was performed based on standardmethods and equipment.
