Some of these materials are in their natural state and they can also be used to improve the mechanical performances of cementitious composites. Sheep wool, which is nowadays considered a special waste, can substitute some polymeric fibres to increase the fracture toughness. However, in alkaline environment, wool fibres tend to degrade within a few days after casting, so fibres can lose the reinforcement function of concrete and mortars due to long term durability issues. A series of tests have been performed with the aim of examining the microstructure and measuring the mechanical properties of wool-reinforced pastes made with various types of cement. By linking the results of microstructural analyses with those of the mechanical tests, it is possible to argue that the lower the pH of the paste the larger the efficiency of wool fibres. Keywords:wool-reinforced paste, microstructure analyses, residual strength, degradation, sustainability, eco-friendly material Affiliations:
