abstract = {This paper evaluates a type of geopolymer concrete that uses hemp fibres as a natural
aggregate due to the various advantages offered by these woody materials. These advantages include
ease of cultivation and processing and their use in the essential structure of concretes used for
green construction purposes. The sampling study was prepared using an environmentally friendly
inorganic binder, based on geopolymerization reactions (Si-Na). The improvement in the hemp
aggregate using two different preservation methods (fresh and wet) was assessed. The type of
conservation enables anaerobic reactions to take place in the structure of the hemp, in such a way as
to modify the proportions of the organic compounds contained in the hemp and the morphology
of the fibres. It also encourages the proliferation of cellulose nanofibrils (CNC), which enhance the
mechanical results, improving plasticity and thixotropy. The hempcrete studied in this paper could
be a good alternative material for sustainable, environmentally friendly construction, as much less
CO2 is emitted during the production process in comparison with conventional concrete. Using
wet-preserved hemp means that less water must be added to the mix during preparation of the
concrete. This also helps reduce production costs, and by extension, the cost of the final product.},
