Use of technical hemp for concrete - Hempcrete

Popis výsledku v původním jazyce

We live at the time of trying to reduce the carbon footprint, which also involves the production of building insulation. Today's trend is the construction of passive houses with the best insulation and reduced heating costs. By reducing the incineration of non-renewable sources for heating, we will reduce the carbon footprint, but by increasing the classical building thermal insulation, whether based on plastics or minerals. A suitable option is natural materials. This article deals with the use of technical hemp in concrete. Hemp is a historically widely used plant, but its decline has occurred due to its similarity to the THC variety, so this plant is now more known for its narcotic effects. For use in construction, industry, etc., the Cannabis Sativa L. variety, so-called Technical Hemp with negligible THC content, is used. Today, the use of technical cannabis is rediscovered. By adding technical hemp to the concrete, we improve the thermal properties of the concrete to the detriment of strength properties. The article describes different properties of the hemp concrete compared to the conventional concrete. In the building construction industry, it is known for the use in the cannabis insulation, hemp concrete, hemp oils and varnishes, Honeycomb plaster, ropes and strands. The best known are the cannabis insulation in the form of mats and hemp ropes, but there is also a widespread use of cannabis, which is discussed in this article. By measuring, the compressive strengths of the cannulated concrete were 1.13 MPa, which is comparable to that of the lightweight concrete and foam concrete. From this finding, that hemp concrete can be used as a filler material, nickels as a carrier material. This concrete can be used as a binder, both hydraulic lime and cement. However, when using cement, it is necessary to mineralize the shaker, which is a laborious and long-lasting activity.
