Gypsum compounds with the addition of post-consumer textile fibres of cotton

Sustainability in construction is key in reducing the consumption of resources such as materials and energy, it is essential to adopt efficient actions in construction processes such as the reuse of waste. Therefore, this paper analyzes the influence of the incorporation of post-consumer textile waste of cotton on the physical-mechanical properties of gypsum compounds. An experimental work was carried out where plaster specimens were tested added with post-consumption cotton fibers in different formats, and lengths (20 and 35mm), additions of 0.5% and fibers of 35mm in length increased the resistance to flexion and compression by 5.9% and 11% respectively, and the absorption of water by capillarity decreased by 26% with 1% addition. Finally, it was observed that the fibers reduce the detachment of gypsum fragments when reaching the breaking load, improving the toughness of the compounds
