摘要：One of the objectives of sustainable development in
construction is the use of low-processed materials. They have a positive
impact on the ecological balance of the building throughout the entire life
cycle. Examples of such materials are materials of plant origin - straw,
shives, cellulose fibers. They are used as thermal insulation or wall
material. In recent years, hemp shives are increasingly used as
a component of a lime-based composite, which performs the function of
wall filling in timber frame constructions. The shives, due to the high
porosity, determine the high thermal insulation properties of the composite.
The physico-mechanical properties of the composite can be modified
depending on various factors, including the ratio of hemp shives to the
binder. The lime binder, in turn, can be modified by hydraulic and
pozzolan additives. The paper presents mechanical properties (compressive
and flexural strength) as well as physical properties (density, porosity,
thermal conductivity coefficient, absorbability) of composites with various
proportions of hemp shives of the Bialobrzeskie variety to the lime binder
modified with Portland cement and metakaolinite.
