“…Setién et al suggested that LF slag could develop certain hydraulic properties and could therefore be recycled for construction and civil engineering applications. This conclusion has been supported by other authors [31][32][33][34], who suggest using LF slag in the manufacture of mortars.…”

“…In particular, the Fe 2 O 3 content that was reported (26.36%) is much higher than the typical Fe 2 O 3 content in LFS (<7 wt.%). This conclusion can be corroborated by reviewing the composition differences between EAF slag and LFS [65,66] More recently, Manso et al [33] and Rodriguez et al [34] examined the possibility of manufacturing mortars with LFS. The contents of CaO and MgO in the LFS used in these works were approximately 56% and 10%, respectively.…”

“…This effect can be explained by the pozzolanic nature of slag fines that react chemically with calcium hydroxide of clinker at ordinary temperature to form compounds possessing cementitious properties. When admixtures are used, the strength weakens, which is logical as they are mortars with larger quantities of occluded air [27].…”

“…Increasing amounts of solid waste are produced, placing constraints on the availability of landfill sites, with a consequent rise in disposal and dumping costs (4). The current research examines the viability of introducing various wastes of industrial origin in a gypsum matrix (5)(6)(7)(8). The aim is to reduce the weight of the gypsum and to improve its thermal properties.…”

Gypsum plasterboard that incorporates various combinations of polyurethane foam waste and polypropylene fibers in its matrix is studied. The prefabricated material was characterized in a series of standardized tests: bulk density, maximum breaking load under flexion stress, total water absorption, surface hardness, thermal properties, and reaction to fire performance. Polypropylene fibers were added to the polyurethane gypsum composites to improve the mechanical behavior of the plasterboard under loading. The results indicate that increased quantities of polymer waste led to significant reductions in the weight/surface ratio, the mechanical strength and the surface hardness of the gypsum, as well as improving its thermal resistance. The polypropylene fibers showed good adhesion to the polymer and the gypsum matrix, which enhanced the mechanical performance and the absorption capacity of these compounds. The non-combustibility test demonstrated the potential of the new material for use in internal linings. RESUMEN: Caracterización de placas de yeso con residuos de espuma de poliuretano reforzadas con fibras de polipropileno.Este artículo presenta un estudio experimental basado en la reutilización de residuos de poliuretano en una matriz de yeso para elaborar una placa de yeso laminado. Las placas fueron caracterizadas mediante los ensayos normalizados de densidad aparente, carga de rotura máxima a flexión, absorción total de agua, dureza superficial y reacción al fuego. Se han introducido fibras de polipropileno en la matriz con el objetivo de aumentar la resistencia mecánica del material. Los resultados muestran que el incremento de residuo polimérico en el material implica importantes reducciones de peso, resistencia mecánica y dureza superficial, a la par que se mejora su resistencia térmica consiguiéndose valores similares a los comerciales. Las fibras de polipropileno mostraron una buena adhesión con el polímero, mejorando el comportamiento mecánico y la capacidad de absorción. El ensayo de reacción al fuego confirmó que los residuos de poliuretano pueden ser empleados en la fabricación de placas de yeso laminado en cumplimiento con la normativa.
