This research analyzes the durability of mineral wool waste from insulation materials used in the construction industry as reinforcement elements in cements matrices. In order to do this, an experimental plan was drawn up, detailing the production of cement mortar samples containing different types of fibers from insulation waste, on which freeze-thaw, salt crystallization, water vapor permeability, occluded air content and workability period tests were performed, in order to assess their use as raw materials. The test results show that the properties of these new mortars, containing insulation waste, remain optimal over time making them a sustainable alternative for use in outdoor settings.

The objective of this study was to analyze the physico-mechanical properties of gypsum boards including plastic waste aggregates from cable recycling. The plastic cable waste is incorporated into the gypsum matrix without going through any type of selection and/or treatment, as it is obtained after the cable recycling process. In the experimental process, gypsum boards of different dimensions were manufactured and tested for their Young’s modulus, shock-impact resistance, flexural strength, thermal conductivity, and thermal comfort. The results obtained show a significant increase in the elasticity of the boards with plastic waste (limited cracking), compliance with the minimum value of flexural strength, and a slight improvement in the thermal conductivity coefficient (lower energy demand) and surface comfort (reduced condensation and greater adherence). Therefore, the analyzed material could provide a suitable alternative to currently marketed gypsum boards, contributing to sustainable construction not only in new constructions, but also in building renovations.

This article analyzes the effect of fire on plasterboards containing plastic cable aggregates. Before, their physical and mechanical properties have been studied and published, whose results comply with the applicable regulations. In this research, considering the plaster coating to be a passive means of trying of reduce the flammability of the aggregate polymers. In construction materials, and more specifically, materials containing polymers, fire resistance is a requirement in which it is necessary to examine the effects and emission of gases from the combustion. To verify the initial hypothesis, a real test was performed, using a direct fire set in a Madrid fire station, making calculations by estimating the gas emissions of a fire in a hypothetical room. The results reflect the contribution of the plaster, acting as a physical barrier to the passage of heat and/or volatile substances, in delaying the fire’s effect on the polymers. In addition, using plastic waste from cables as a secondary raw material, the number of incinerations necessary in landfills receiving this type of waste may be reduced, thereby decreasing the potential emission of contaminants into the atmosphere and contributing to the sustainability of our planet.

Nowadays, nobody can deny that climate change is a reality and that the life cycle of buildings contributes greatly to that reality. Therefore, proposals such as the circular economy must be integrated into the construction sector. This article shows part of the results of a research project whose objective is to introduce circular economy criteria in building materials, seeking new uses for construction and demolition waste from buildings. In particular, this article analyses the possibility of replacing fibres currently used to reinforce cement mortars with recycled fibres. After consulting the bibliography, we can conclude that some studies analyse the behaviour of cement mortars reinforced with different types of fibres, but none has been found that analyses the behaviour of these mortars for the application of continuous coatings. For this purpose, a two-stage experimental plan is designed to test cement mortar samples with different types of fibres, recycled fibres and commercial fibres, taking into consideration the characteristics that these mortars have to comply to be applied as continuous coatings. Moreover, a detailed study about the porosity of these mortars and its influence on how the mortars behave with regard to compression, water vapour permeability and impermeability has been conducted. From the results obtained, it can be concluded that the mortars containing recycled fibres have very similar resistance, absorption and permeability values to those containing commercial fibres, so that they might be suitable for application as external coatings.

The aim of this article is to analyse the water-resistant properties of gypsum compounds with plastic cable waste added in order to determine the suitability of their use as an alternative to combat moisture problems in buildings. In the experimental process, test samples were made and subjected to capillary water absorption, water vapour permeability, wet chamber, water-stove cycle and total water absorption tests, and their porosimetry was also studied using the mercury porosimetry test. The results showed a significant decrease in water absorption and retention capacity. This is due in part to the reduced pore volume of the compounds that is achieved without affecting the hygrothermal properties of the gypsum products and keeping their mechanical properties above the minimum values indicated in the regulations. Thus, the material studied is a good alternative to the gypsums currently available on the market to be applied in the areas of buildings most exposed to water and it contributes to reduce environmental impacts.

El artículo presenta los resultados de una investigación propia que confirma la posibilidad de reutilizar materiales de desecho: la fracción fina del hormigón que se recicla como sustituto de arena, residuos de material aislante (lana de roca y fibra de vidrio) y arena reciclada. Se realizaron ensayos de Resistencia a compresión y flexión, absorción de agua por capilaridad y dureza superficial. Los resultados muestran que todos los materiales descritos podrían servir como solución aceptable para la reducción del uso de recursos naturales - arena natural (por ejemplo) o, como relleno. La reutilización de residuos en el mundo debe llevarse a cabo debido a la carencia de recursos naturalesAbstractThe paper presents the results of own research confirming the possibility of reusing a waste material: fine fraction from concrete recycling as a filler in sand lime products and residues of insulating materials (rockwool and fiberglass) and recycled sand using as a insulating materials. The compressive strength, bending, water absorption, surface hardness and structural research were carried out. The results show that the all of describing materials could be acceptable solution to reduce natural resources - natural sand (for example) or be a filler. Reuse of waste materials to new composites is expected in this world because of lack of natural resources.
