The paper analyses Portland cement and lime's impact on the structure and strength of the composites containing hemp shives as an aggregate. The research aim was to obtain a lightweight material with a compressive strength class close to the lowest strength class of lightweight concrete, i.e. LC8/9. The tests show that using the hemp shives as the aggregate's substitute allows for manufacturing the hemp composite with a compressive strength of about 10MPa. However, improving the composite's mechanical performance has required substantially increasing the binder's volume. Using lime as a mineraliser positively shapes the contact zone between hemp shives and binder.
