In the last few years, research in the field of sustainability has experienced a significant increase in interest between sustainability and other areas (inclusive education, active methodologies, and society). Moreover, the use of mixed research methods (quantitative and qualitative) along with the application of data mining techniques, enables the analysis of information and the connection between the different studies. The objectives of this paper were: (1) To establish the results of the research related to the concepts of sustainability, inclusive education, and disability. (2) To study the key concepts that are detected in the articles selected with respect to the concepts of sustainability, inclusive education, disability, and their relations. In order to do so, two studies were carried out (quantitative and qualitative). In the first study, K-means and heat map clustering techniques were applied. In the second study, the technique of text mining was applied. One hundred and thirty-three scientific papers were studied, of which 54 fulfilled all the inclusion criteria. Three clusters were found in the first study; cluster 1 included the categories: inclusive society, educational innovation, and active methodologies. Cluster 2 included active methodologies and society and economy and cluster 3 included inclusive society and society and economy. In the second study, the highest Krippendorff’s Alpha coefficient were found in articles that linked sustainability with social transformation stemming from a change in education by means of the use of active teaching methods and technological resources. The research moves towards the development of competencies in sustainability at all stages of the educational system, and in all areas of knowledge.

The properties and the behaviour of plaster mortars designed with Polyurethane Foam Waste (PFW) are studied in this investigation. A characterization of the mixtures is completed, in accordance with the technical specifications of European Norms. The incorporation of polyurethane waste foam can yield porous and lighter mortars, with better resistance to water-vapour permeability, although with weaker mechanical strength and higher levels of absorbency. Nevertheless, suitable mechanical strengths were achieved, resulting in a new material that is compliant with the requirements of the construction industry. The use of PFW in the the manufacture of gypsum mortars for construction reduces the consumption of natural resources and, at the same time, recovers an industrial waste that is otherwise difficult to recycle.

Present waste management policies aim to reduce waste environmental impacts and improve resources’ efficiency. The use of waste and recycled materials to develop green construction materials are attracting researchers worldwide to develop new solutions addressed to increase the sustainability of buildings. This work presents a study of a new recycled mortar panel from the point of view of its contribution to the sustainability of buildings. Materials from industrial waste, as rigid polyurethane foam and electric arc furnace slags, are used as an additive of prefabricated mortar panels. The new proposed panels must have good thermal behavior with respect to the heat transfer interactions with the outside temperature and relative humidity, when compared to traditional brick or concrete. A test building with two kinds of representative uses, which are both residential and tertiary, and located in three cities of Spain with different climates, will be energy simulated in order to assess the thermal behavior of new construction or refurbished opaque ventilated façades with the new mortar panel. The thermal behavior of the new mortar panels would be studied by means of two energy assessments: (i) the evaluation of the influence of the new mortar panel in the energy demand of the whole building when compared to traditional materials, and (ii) the detailed analysis of the transient inner surface temperature of the space walls when using the new mortar panel. Based on the results obtained from the energy simulations performed, it follows that the thermal behavior of the mortar panel is, at least, equivalent to those of the other two materials, and even better in some aspects.

In the European Union, the demand for polyurethane is continually growing. In 2017, the estimated value of polyurethane production was 700,400 Tn, of which 27.3% is taken to landfill, which causes an environmental problem. In this paper, the behaviour of various polyurethane foams from the waste of different types of industries will be analyzed with the aim of assessing their potential use in construction materials. To achieve this, the wastes were chemically tested by means of CHNS, TGA, and leaching tests. They were tested microstructurally by means of SEM. The processing parameters of the waste was calculated after identifying its granulometry and its physical properties i.e., density and water absorption capacity. In addition, the possibility of incorporating these wastes in plaster matrices was studied by determining their rendering in an operational context, finding out their mechanical resistance to flexion and compression at seven days, their reaction to fire as well as their weight per unit of area, and their thermal behaviour. The results show that in all cases, the waste is inert and does not undergo leaching. The generation process of the waste determines the foam’s microstructure in addition to its physical-chemical properties, which directly affect building materials in which they are included, thus offering different ways in which they can be applied.

The fatigue behavior of lightweight polyurethane foam waste cement mortars was analyzed, in which the sand is replaced by polyurethane waste in volumetric proportions of 50%, 60% and 75%. For this purpose, having calculated the static modulus of elasticity of the mortars, successive loading and unloading cycles under compression are performed. These tests confirm the fatigue capacity and structural properties of the mortars, aspects that are indicative of their long-term durability and suitability for use in masonry works. Two test phases were performed with increasing and variable loads of 20% and 90% of the breaking strain, reaching 300,000 cycles in the first phase and 525,000 in the second one. Both phases showed that the cement mortars with substitutions of up to 60% of sand by polyurethane foam waste were capable of withstanding loading and unloading cycles similar to the conditions of typical masonry mortars in construction works. The results underlined the long-term durability of these lightweight recycled materials. Their good fatigue behavior could be corroborated through the images taken by computerized axial tomography. No significant fractures were observed when comparing the sections before and after the loading cycles, which indicates that no structural collapse took place.

The characterization of a new gypsum mortar-based composite material that incorporates various combinations of polyurethane waste in its matrix is reported in this paper. The new material, a lightweight plate for use in internal ceilings, is characterized in a series of standardized tests: bulk density, mechanical behavior, and the reaction to fire test. Moreover, the study details the industrial manufacturing process linked to the integration of waste from the plastics industry. Increased quantities of polymer waste caused significant reductions in bulk density and mechanical strength, although with reasonable behavior of the plates up to substitution levels of 50%. The non-combustibility test demonstrated the potential of the new material for interior use in buildings. The technology of the new gypsum mortar-based material and polyurethane waste could potentially maximize the reuse and the life-span of this type of waste that would otherwise be incinerated or dumped on landfill sites.

Introduction:The use of polymer wastes in pavement as road is an increasing trend in the road construction sector. Those new pavements reduce the amount of solid waste disposed into landfills and provide more sustainable construction due to the use of in-situ materials. Polyurethane foam waste is a thermostable polymer being used in the form of a grey-coloured foam, a by-product of the automobile industry.Aim:The focus of this work centers on the exploitation of polyurethane foam waste in full or partial substitution of the fines and the mineral powder that form the bituminous mixtures to produce a sustainable alternative for bituminous asphalt used in pavement construction.Methods:A series of specimens were manufactured and tested for the Marshall test, with different percentages of polyurethane foam waste aggregates (50% and 100%), calculating their apparent densities.Results:The results show acceptable compatibility between the elements of bituminous concrete and the polyurethane waste, producing a reduction in both the apparent density and Marshall stability, as well as an increase in volume and an increase in deformation with higher volumes of waste in the mixture.

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.

One of the most extensive applications of recycled construction and demolition waste is as recycled aggregate in substitution of natural aggregate. An application for the fine fraction is investigated in this study by preparing lightweight mortars with different types of fine recycled aggregate from concrete waste and rubble. The properties of the materials are evaluated by means of physical and chemical characterization, their mechanical properties are tested, and the economic viability of the final product evaluated. In conclusion, despite the significant differences noted between the lightweight mortars and those incorporating natural aggregates, the former remain a technically and economically viable alternative.

A durability study is presented of masonry mortars prepared with varying quantities of electric-arc furnace slag (EAFS) and ladle furnace slag (LFS) in the same mixtures, in substitution of natural fine aggregate. The behavior of the mortars subjected to freeze-thaw cycles, wet-dry cycles, marine environments, salt crystallization tests, and industrial atmospheres (Kesternich test) is studied. Comparative results are reported for these different dosages of steel slag aggregates (between 25% and 100%), in substitution of natural fine aggregate in the mortars, which moreover employ commercial additives in their mixtures. Having finalized the accelerated aging tests, the specimens are tested under compression and flexion and their mechanical strengths after 90 days of curing compared with the mechanical strengths of the same materials without aging. The tests confirmed the long-term durability of the mortars that included large amounts of steel waste. These results can contribute to achieving the goals of maximum resource exploitation and progressive waste reduction towards which society is advancing.

Mortars made with Portland cement, sand, water and recycled polyurethane foam from industrial waste, including surfactants, are examined in this study. The research was carried out on the influences of the additives on the physical and mechanical properties of these recycled mortars. Results show that in spite of the porosity increase and apparent density decrease with the incorporation of polymer, mechanical strength remains enough or even higher than the reference samples that do not include polyurethane. Microstructure was analyzed by scanning electron microscopy (SEM), and the study was completed with a reconstruction of the macrostructure by Computerized Axial Tomography
