| Resumo: | At present, the development of new eco-friendly building materials for the production of lightweight partitions has become a challenge in order to advance towards the industrialization of the building sector. This work aims to design, characterize, and analyze the possibilities of applying innovative ecological gypsum composites lightened with hemp. To achieve this, samples have been prepared with partial replacement of 15% and 30% in volume of the original gypsum material by adding hemp both in the form of powder and fiber. The results show how the replacement of 15% of gypsum by hemp fiber with a length between 8 and 12 mm improves the flexural strength of the composites. Likewise, all the dosages prepared for this study have met the minimum requirements for mechanical strength required by current regulations, while also improving the water resistance behavior of gypsum composites. However, the main advantage derived from the use of these hemp-lightened gypsum-based materials lies in their reduced thermal conductivity, being up to 50% lower than that obtained for traditional materials. These results suggest the possible application of these materials to produce prefabricated boards and panels for a more sustainable construction. |
