The paper presents an analysis of the influence of high temperature on the mechanical strength and structure of hemp concrete. Hemp shives were used as an aggregate. The volumetric content of the hemp shoves in concrete was constant; the binder-to-hemp shives ratio was 1.3. Concrete specimens were prepared using three types of binders: lime, cement-lime and Portland cement. The research program covered testing the concrete’s compressive strength and mass loss after heating up to 450°C. The thermogravimetric analysis of the hemp shives and tested concrete specimens have also been carried out. It has been demonstrated that the hemp concrete’s strength at the temperature up to 450°C depends on the binder used.
