Influence of the Direction of Mixture Compaction on the Selected Properties of a Hemp-Lime Composite
The aim of the research presented in the article was to check the differences in the hygro-thermal and mechanical properties of hemp-lime composites with different shives fractions, depending on the direction of mixture compaction. The research part of the paper presents the preparation method and i...
