Quantitative study of triboemission kinetics from polymer fiber-reinforced mortar paving blocks: Unravelling the dynamics of nanoparticle aerosol release Husanu, Francisca Alonso Díez, Álvaro Calderón Carpintero, Verónica Castellote, Marta Nevshupa, Roman Mortar paving blocks Waste additives Recycled polyurethane fibers Nanoparticle aerosols Triboemission of nanoparticle aerosols from construction materials is a growing concern due to its potential impact on air quality and human health. In this study, we investigated the effect of aggregation of polyurethane fibers (PUFs) proceeding from waste on the kinetics of triboemission in cement mortars. A quantitative methodology was employed to assess the deposition rate, particle size distribution, and emissivity for the aerosols within the particle aerodynamic diameter range of 10–400 nm. The triboemission properties were correlated with the pore structure, morphology and tribochemical transformations of the particles and worn surfaces. Our results highlight the intricate influence of PUF aggregation on the kinetics of triboemission in cement mortars through both direct and indirect mechanisms and provide valuable insights into the mechanisms governing triboemission in construction materials. 2026-01-13T11:47:47Z 2026-01-13T11:47:47Z 2026-01-13T11:47:47Z 2024-08 info:eu-repo/semantics/article 0008-8846 https://hdl.handle.net/10259/11206 10.1016/j.cemconres.2024.107650 eng Cement and Concrete Research. 2024, V. 185, p. 107650 https://doi.org/10.1016/j.cemconres.2024.107650 http://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess Atribución-NoComercial 4.0 Internacional Elsevier
