Lime-Based Plaster Reinforced with Hemp Braids as Sustainable Building Product

Sustainability is of fundamental importance for the construction industry: in recent decades researchers focused on supplementing building components with multiple natural fibres, evaluating their mechanical performance and application fields. In this field, common plasters are usually equipped glass fibre mesh to avoid crack patterns due shrinkage. Natural thanks high tensile resistance, can represent a green solution solve problem. particular, work investigates properties characteristics biocompound obtained hemp fibres. The first phase aims at identifying ideal mixture between fibres mortar improve workability altering water/lime ratio. performed physical tests provide useful information evaluation consistency compound. Based these preliminary results, 10 combinations 3 parameters, namely diameter, percentage length braid fragments, tested. Among properties, bending, compressive behaviours evaluated. For each test, performances fibre-reinforced samples compared reference specimens. From it noted that best were from diameter 1 mm 2 cm. On other hand, flexural tests, seen braids cm an average bending stress about 13% less than control specimen. Contrarily, give mean increase 8%
