    The influence of the slaking method on the characteristics of lime putties has been investigated. There has been used the same raw lime, calcined in a traditional kiln, to perform in situ traditional slaking processes as well as laboratory controlled slaking processes. The obtained lime putties were characterized using different instrumental techniques such as X-ray diffraction (XRD), X-ray fluorescence (XRF), thermogravimetric analysis (TGA), specific surface area (BET), particle size using laser dispersion and viscosity. Particle morphology using scanning electron microscope (SEM) was also studied. The amount of water used during slaking as well as the temperatures distribution give raise to differences in the particle size distribution and in the resulting hydration products.

    The present work deals with the development of new rigid polypropylene composite foams filled with high amounts of flame-retardant systems based on synthetic hydromagnesite, a basic magnesium carbonate obtained from an industrial by-product. A partially-interconnected cellular structure with a cell size around 100 micrometers was obtained for the hydromagnesite-filled PP foams. A 40% reduction of this cell size was observed when a small amount of a combination of montmorillonite and graphene layered nanoparticles was added to the hydromagnesite. The combination of hydromagnesite with an intumescent additive (ammonium polyphosphate) and layered nanoparticles led to improved thermal stability. In particular, the intumescent additive delayed the beginning of the thermal decomposition temperature and the layered nanoparticles split the second step of thermal decomposition in a third peak observed at higher temperatures. Improved flame retardancy, measured by means of cone calorimetry, was observed in the samples containing the intumescent additive. A novel normalized parameter, called foam efficiency ratio (FER), which takes into account the expansion ratio of the foam and the relation of its fire properties with that of the base solid, was also analyzed.

    This paper is a teaching activity carried out on the subject of Building Materials from Building Engineering studies. This subject is developed in the second year and lasts for a four month period. The student teacher ratio is around 60:1. The goal of this work was the development of a new building material obtained from waste materials. Students were divided in teams of three students chosen by themselves. This activity helped students to develop knowledge about different materials and make them aware of the importance and possibilities to profit waste materials. Students should work with materials studied in the subject, mainly clay, glass, steel, wood and plastics. Before beginning they must do an important bibliographic research about the topic they wanted to develop. The university provided the use of lab facilities and the guidance of the teacher. Besides following up the work, the teacher encouraged the students to perform some tests on the new material obtained. Finally they should come out with a poster and a sample of the material. Results got from different works differed substantially according to the interest and time dedicated to them. Most of the students abused of the use of polymeric resins to elaborate the new materials, and therefore, even using wastes the new materials were not so sustainable. The use of natural materials such as cane fibres leaded to materials with interesting insulation and structural properties. It was a very good experience to attract students to materials research. Finally we discovered in order to get profitable results, this kind of activity should cover a longer period and should count with the continuous guidance of the teachers.

    In this work we have studied the effect of different flame retardants on the fire behavior and mechanical properties of epoxy mortars. Flame retardants acting under different mechanisms of action have been compared: phosphate flame retardants as well as magnesium hydroxides and carbonates. Besides the commercial flame retardants we have also used a magnesium basic carbonate obtained from an industrial by-product. The use of an alternative based on an industrial by-product combines an economic and sustainable solution. Different formulations of flame retarded epoxy mortars have been prepared and characterized. The obtained results prove the effectiveness of the tested flame retardants on the improvement of the fire properties of the epoxy mortars without a significant decrease on their mechanical properties.

    Boron-based formulations are used to improve the service life of timber. On the one hand, boron-treated wood increases resistance to biological attacks (e.g. by fungi and insects), and on the other hand, it renders wood more resistant to burning. In the present study, we analyse the fire behaviour of some water-borne formulations containing boron. A completely inorganic formulation (disodium octaborate tetrahydrate (DOT)) is compared with new-generation tannin-based wood preservatives in which the flavonoid network is used to fix the boron to wood. The study of the fire behaviour was carried out according to four specific fire tests: (i) dripping; (ii) short-term exposure; (iii) long-term exposure and (iv) the limiting oxygen index. The Scots pine (Pinus sylvestris L.) specimens treated with DOT have shown a complete efficacy against fire after all tests were completed. It should also be noted that very positive results have also been achieved by the tannin-based solutions. DOT has to be preferred when high performance is required, but exclusively for interior applications. The use of tannin-based formulations can be suitable for outdoor fire protection and also for indoor applications when specific aesthetic requirements should be fulfilled

    En el presente trabajo se han preparado y caracterizado espumas ignífugas de poliolefinas libres de halógenos. Se ha utilizado para ello una formulación comercial, empleada típicamente en la industria de cables, y se le ha añadido pequeños porcentajes másicos (entre 2 y 4%) de dos sistemas retardantes de llama: "sílice-borato de zinc" y manolaminillas de "montmorillonita y grafeno expandible". Durante la caracterización celular de las espumas, preparadas por espumación química utilizando como agente espumante azodicarbonamida, se ha constatado que la presencia de las nanopartículas promovía una estructura celular con tamaño de celda más pequeño. Mediante un análisis termogravimétrico, se ha observado un aumento del residuo inorgánico de la formulación base a temperaturas superiores a 500ºC. Esta observación puede ser debida, en cierta medida, a un efecto sinérgico entre ambos sistemas retardantes de llama, el cual promueve una mayor estabilidad térmica de la formulación base. Durante la caracterización del comportamiento frente al fuego mediante ensayos de cono calorimétrico, se ha constatado que el sistema "síliceborato de zinc" retarda en tiempo hasta ignición de la llama (mayores valores de TTI) y que la presencia de las nanopartículas disminuye el valor del PHRR (máxima tasa de liberación de calor).

    Phase change materials (PCM) have been proved to be an effective tool to regulate indoor temperature fluctuations and reduce the energetic demand of buildings [1,2]. Paraffins are among the most common PCM used for thermal storage in building applications. A broad range of melting temperatures, with an elevated heat of fusion associated, can be obtained varying the length of the hydrocarbon chain that forms the paraffins. Furthermore, they exhibit numerous benefits such as the nearly absence of supercooling, chemical stability, low vapor pressure during the phase change and no phase segregation [3]. These paraffins can be incorporated in several forms to building materials like gypsum or concrete [4]. Despite all these advantages, one major concern regarding the paraffins as PCM is their possible contribution to flame propagation in case of fire [5]. Several authors have tried to improve this aspect by combining the paraffins with HDPE polymers to obtain a form-stable PCM [6]. Blends of paraffin and polyethylene usually contain some inorganic filler, which can act improving both the thermal conductivity as well as the flame retardancy of the system [3, 7]. Microencapsulated PCM or paraffins adsorbed in a substrate are designed to be incorporated directly into the building material and, therefore blending with HDPE is less interesting. Another possibility to increase the fire performance of the PCM is the addition of flame retardants directly into the matrix-PCM mixture. Paraffins usually present their combustion between 220-320ºC and therefore the flame retardants selected should act in this temperature range. In this work we have studied the effect of different loads of PCM on the fire behaviour of gypsum boards. In order to improve the fire behaviour of the gypsum-PCM system, two different types of flame retardants have been added. We have chosen two endothermic flame retardants: aluminium hydroxide (ATH) and a synthetic basic magnesium carbonate, hydromagnesite (HM), obtained from an industrial by-product. Both FR have an endothermic decomposition starting around 200ºC and can be found among the cheapest alternatives to achieve flame retardancy.

    In this paper we prepared and characterized several polyurethane composite foams by combining variable concentrations of organophilic clay (montmorillonite) and metal reinforcement, with the objective of developing novel multi-scalar multifunctional rigid foams. The addition of montmorillonite clay promoted foaming and the formation of finer and more homogeneous cellular structures, resulting in foams with compressive elastic moduli and collapse stresses lower than that of the unfilled polyurethane foams. However, a comparative analysis versus the foams’ relative density demonstrated that both mechanical properties follow one single trend for the two materials. The combination of montmorillonite and metal reinforcement further reduced the cell size of foams, ultimately resulting in foams with similar mechanical properties for considerably lower relative densities. Although no important differences in thermal conductivity were found for the polyurethane foams with adding montmorillonite, the incorporation of the metal reinforcement led to considerably higher thermal conductivities, its value increasing with increasing relative density.

    This study assesses the processing behaviour and mechanical properties of different thermoplastic polymers filled with Electric Arc Furnace Dust (EAFD). Design of Experiments (DoE) approach enabled the evaluation of the influence of each component and the interactions between them. There were prepared different composite formulations varying the content of EAFD. The mechanical properties and the melt flow index (MFI) of composites were selected as output responses and the effect of CaCO3, BaSO4 and EAFD fillers as well as different polymer matrixes were evaluated. It was observed that slight variations in the formulation yield to a broad range of response values. Polyethylene-co-vinyl acetate (EVA) concentration showed a significant effect on all responses. It was found that the presence of EAFD increased fluidity and decreased the elasticity modulus and the elongation at break. In addition, when added with barite, the presence of EAFD caused an increase of the tensile strength.

    Low-grade magnesium hydroxide is being used with very promising results as flame retardant filler in polymeric materials and as aggregate in the formulation of mortars for passive fire protection, combining an economic and sustainable solution. Simultaneous TGA–DSC was used to evaluate low-grade magnesium hydroxide thermal decomposition in order to examine the suitability of this product for a broad range of temperatures. Thermal analysis in air shows an unexpected exothermic peak, as well as the endothermic peaks corresponding to the decomposition of magnesium hydroxide, magnesite and dolomite. Thermal decomposition using nitrogen as gasflowdoes not show the exothermic peak, whereas anewendothermic peak corresponding to decomposition of calcite appears. In situXRDpatterns collected in air atmosphere at high temperature allows determining the presence of anhydrite, which was related to direct sulphation of calcite from the sulphur trioxide generated during the combustion of petcoke adsorbed on the particle surface of the low-grade magnesium hydroxide

    En el desarrollo de materiales aislantes acústicos para sectores como la automoción, se utilizan habitualmente compuestos poliméricos con un contenido en cargas inorgánicas superior al 70% en peso. Este hecho obliga a utilizar matrices que mantengan en el compuesto la ductilidad necesaria para su termoconformado. En este trabajo se ha aplicado el diseño estadístico de mezclas al estudio del comportamiento térmico y mecánico de mezclas preparadas con dos grados de EVA de diferente contenido en acetato de vinilo y un plastómero de etileno y buteno. En particular, se ha estudiado la evolución de las entalpías y temperaturas de fusión y cristalización, así como la estabilidad térmica y el comportamiento mecánico de las mezclas en función de su composición.

    El endurecimiento del cemento Portland se debe fundamentalmente a la hidratación de los silicatos bicálcicos (C2S) y tricálcicos (C3S) presentes en el polvo de cemento. Los compuestos hidratados, de estructura tipo gel o amorfa, son los que otorgan la resistencia mecánica al cemento y a los materiales que lo utilizan como conglomerante (morteros y hormigones). A pesar de que se considera que la resistencia máxima se adquiere a los 28 días, la hidratación de estos silicatos puede no ser completa. En este trabajo se han analizado las diferentes fases presentes en pastas de cemento preparadas en el laboratorio y en muestras de hormigón extraídas de obra. Para ello, se han realizado observaciones ópticas de lámina delgada y se han utilizado técnicas de difracción de rayos X (DRX) y de nanoindentación. Los resultados de DRX han revelado diferencias significativas en la naturaleza y porcentaje de las fases cristalinas en función del envejecimiento de las muestras. Mediante las medidas de nanoindentación se han determinado las propiedades mecánicas, módulo elástico y dureza, de las diferentes fases.
