| In the context of sustainable construction, the use of low-processed and low-embodied-energy materials is a growing priority. Lightweight expanded clay aggregate (LECA) is a commonly used material due to its favourable mechanical and thermal properties. This study investigates the modification of LECA by incorporating a waste product derived from hemp stalks processing—a fine fraction of hemp shives, which are too small to be used, for example, in hemp concrete. The introduction of this organic component into the clay matrix significantly influences the internal structure of the aggregate after firing it, increasing its porosity. This increase in porosity has a direct impact on enhancing the thermal insulation performance of the resulting material. Clay-hemp mixtures with various proportions of fine hemp shives were prepared and subjected to laboratory testing to determine their bulk density, thermal conductivity, porosity, and water absorption. The developed clay aggregate with the addition of hemp stalk waste was intended for use as an insulating material in ground-supported floor systems in buildings. This solution offers a sustainable alternative to traditional materials such as sand or concrete. The use of the hemp by-product is both cost-effective and environmentally friendly, as it supports waste recycling and reduces the consumption of conventional raw materials. |
