      <description>Title: Reactions of fly ash with calcium aluminate cement and calcium sulphate
Authors: Fernández Carrasco, Lucía; Vázquez Ramonich, Enric
Abstract: The hydration processes in the ternary system fly ash/calcium aluminate cement/calcium sulphate (FA/CAC/C$) at 20 °C were investigated; six compositions from the ternary system FA/CAC/C$ were selected for this study. The nature of the reaction products in these pastes were analysed by X-ray diffraction (XRD) and infrared spectroscopy (FTIR). At four days reaction time, the main hydration reaction product in these pastes was ettringite and the samples with major initial CAC presented minor ettringite but calcium aluminates hydrates. The amount of ettringite developed in the systems has no direct relation with the initial components.</description>

      <description>Title: New analytical model to generalize the Barcelona Test using axial displacement
Authors: Pujadas Álvarez, Pablo; Blanco Álvarez, Ana; Pialarissi Cavalaro, Sergio Henr; Fuente Antequera, Albert de la; Aguado de Cea, Antonio
Abstract: The Barcelona Test has proved to be very suitable for the systematic control of the tensile properties of Fibre Reinforced Concrete (FRC). Nevertheless, the need to measure the total circumferential opening displacement (TCOD) of the specimen entails the use of an expensive circumferential extensometer. In order to simplify the test, studies from the literature propose the use of the axial displacement of the press (δ) instead of the TCOD, obtaining empirical equations to correlate the energy estimated with both measurements. However, these equations are only valid for δ ranging from 1 to 4 mm and were adjusted based on the test results of just a few types of FRC. The verification of this formulation for other types of FRC shows an average error of 51.1%, thus limiting the simplification proposed for the test. In this paper, a new analytical model to convert the δ into the TCOD is developed and validated for a wide range of FRC. Besides being applicable to the whole range of δ, the new model provides a clear physical understanding of the main mechanism observed during the test and shows an average error of only 6.7%, making it possible to simplify the Barcelona test.</description>

      <description>Title: Recycling silicon solar cell waste in cement-based systems
Authors: Fernández Carrasco, Lucía; Ferrer, R.; Aponte Hernández, Diego Fernando; Fernández, P.
Abstract: This is a study of the recycling of crystalline solar cells by incorporating them in cement matrices. The hydration process of a mixture of calcium aluminate cement (CAC) and solar photovoltaic cell waste was researched and analyzed. The nature of the hydration products of various compositions of these mixtures was evaluated at a temperature of 20 1C by analyzing the samples through X-ray diffraction, infrared spectroscopy and scanning electron microscopy. The total porosity and mechanical strength development of these materials were also determined. It was revealed that the presence of a solar cell residue of up to 5% in the cement matrices does not result in new hydration products that are different from those derived from the normal hydration of the CAC cement. Moreover, the material developed can be considered as an expansive cement blend because it releases H2 at early stages. The presence of waste causes a decrease in the mechanical strength and an increase in the total porosity of this material, but it can be used for applications such as thermal insulation</description>

Authors: Gangolells Solanellas, Marta; Casals Casanova, Miquel; Forcada Matheu, Núria; Fuertes Casals, Alba; Roca Ramon, Xavier
Abstract: Certifiable management-system standards apply similar management techniques and principles, but each system still tends to have&#xD;
a separate structure in construction companies. Research and practice have demonstrated that management tasks may be duplicated when&#xD;
standards are implemented in parallel. Consequently, integrated management systems are strongly advocated. However, existing literature&#xD;
demonstrates that the integration of planning and control instruments involves a high level of uncertainty. This paper presents an innovative&#xD;
model to enhance the integration of environmental- and health and safety&#xD;
–&#xD;
management systems in construction companies, focusing on the&#xD;
subsystems for identifying, assessing, and operationally controlling environmental aspects and health and safety hazards and using risk as an&#xD;
integrating factor. The findings of this study have direct implications for both designers and contractors because the model helps to explicitly&#xD;
consider on-site environmental impacts and construction-worker safety during the design process and offers on-site guidance to eliminate the&#xD;
remaining impacts and risks or reduce them to acceptable levels. A case study is reported to illustrate the practical use of the proposed model&#xD;
and its benefits.</description>

      <description>Title: Design of macro-synthetic fibre reinforced concrete pipes
Authors: Fuente Antequera, Albert de la; Campos Escariz, Renata; Domingues de Figueiredo, Antonio; Aguado de Cea, Antonio
Abstract: This paper presents an experimental campaign in which concrete pipes were manufactured using plastic fibres as the sole reinforcement material. In this regard, it has been demonstrated that the use of plastic&#xD;
fibres is compatible with pipe production systems, and that, when subjected to the crushing test (CT), plastic fibre reinforced pipes yield strength classes that are attractive in terms of the growth of this material in the concrete pipe industry. Moreover, the results obtained from both the characterisation of the material and the mechanical behaviour of the pipes have been used to verify that the Model for the Analysis of Pipes (MAPs) is an appropriate tool for the design of such pipes. Finally, this paper presents a direct design methodology which was used to establish the firsts design tables for fibre reinforced concrete pipes presented in the scientific literature. This methodology can be used to estimate the strength requirements of the fibre reinforced concrete needed to reach the strength classes set out in EN 1916:2002, without having to resort to the CT as an indirect design method.</description>

      <description>Title: Influence of building type on post-handover defects in housing
Authors: Forcada Matheu, Núria; Macarulla Martí, Marcel; Fuertes Casals, Alba; Casals Casanova, Miquel; Gangolells Solanellas, Marta; Roca Ramon, Xavier
Abstract: Clients’ lack of involvement in defining quality requirements for dwellings built by developers leads to a perception of poor quality at the time of purchase. The research presented in this paper aims to broaden previous research on defects by analyzing the defects that remain in the post-handover stage, which usually lasts 12 months after the handover period, and identifying the factors that influence the appearance of these defects, determining whether a significant difference exists in the quality of the two main residential building types built by developers: flats and detached houses. It also analyzes and discusses the areas and elements in which the defects were detected. The data were obtained from client complaint forms completed after the handover of 95 dwellings in Spain. The data were then statistically analyzed using a t-test analysis, a Pearson’s parametric correlation, and a chi-square test. The research reveals that clients detect more defects in flats than in detached houses. The lower quality of the materials used in flats and the tighter schedule to which flats are subject may cause these differences.</description>

Abstract: El nuevo método para el diseño de hormigón con árido reciclado (HAR) es usado para&#xD;

Primeramente, se realiza una extensa campaña experimental, para analizar las posibilidades de su aplicación, usando dos áridos reciclados de hormigón (ARH) españoles.

Instrucción de Hormigón Estructural (EHE 2008). Para determinar y analizar las propiedades del hormigón, se llevaron a cabo ensayos de asentamiento, contenido de aire, densidades, módulo elástico y resistencias a compresión.

Abstract: The longitudinal forces introduced by tunnel boring machines (TBMs) to the segmental tunnel linings influence their structural response. The analyses of the linings construction process and the ground-structure interaction mechanisms have shown the influence of the lining creep on the progressive loss of the initial longitudinal force. An analytical formulation to predict the remaining compression of the linings as a function of time is proposed, supported by means of a complete numerical model, which considers the effect of creep during the sequential construction process. An experimental program to determine the creep of plastic packers was developed, revealing its significant influence on the global lining creep factor and the evolution of the remaining compressive stresses.</description>

Abstract: The particular configuration of segmental tunnel linings produces that its structural response in front of usual design loads could present a significant three dimensionality due to the structural interaction between adjacent rings (coupling effects). The present paper studies the phenomena associated to coupling effects, determines the main involved parameters and analyzes their influence on a real lining structural response by means of a 3D numerical model. The comparison with the usual plane models currently employed in linings designs provide significant conclusions about the coupling effects implications and the conditions in which become more relevant.</description>

Authors: Bedynek, Agnieszka; Real Saladrigas, Esther; Mirambell Arrizabalaga, Enrique
Abstract: This paper presents an experimental and numerical research on tapered steel plate girders subjected to shear. Experimental tests included four small-scale tapered steel plate girders. Research was focused on&#xD;
both, critical shear load and ultimate shear resistance. Moreover, the post-buckling behaviour of tapered plates was studied.&#xD;
Further, some parametric studies with various geometries of tapered panels were done in order to find the most favourable design situations. The analysed parameters were: the panel aspect ratio, the inclined&#xD;
flange angle, the web and the flange slenderness.&#xD;
Numerical simulations allowed distinguishing four different typologies of tapered plate girders which should be considered separately in design because of their different behaviour. Verification of the simplified procedure for tapered plates proposed in Eurocode EN 1993-1-5 allowed concluding that for some cases the estimation of the ultimate shear resistance is situated on the unsafe side and need to be revised.</description>

      <description>Title: Assessment of residential defects at post-handover
Authors: Forcada Matheu, Núria; Macarulla Martí, Marcel; Love, Peter E.D.
Abstract: In Spain, the Ley de Ordenación de la Edificación (Building Regulation Act) has established compulsory warranties to ensure that&#xD;
buildings meet basic requirements with regard to functionality, general safety and structure, fireproofing, and use and habitability. Despite the&#xD;
requirements of this regulatory body, defects in newly built dwellings remain a pervasive problem, which has resulted in a plethora of&#xD;
complaints to the&#xD;
Instituto Nacional del Consumo&#xD;
(National Institute for Consumers&#xD;
’&#xD;
Protection), which deals with consumer protection&#xD;
in Spain. In this paper, a total of 2,351 post-handover defects derived from four Spanish builders and seven residential developments&#xD;
are classified according to their location, subcontract, and element. The research reveals that the most common defects identified by&#xD;
customers at handover were incomplete tile grouting and incorrect fixtures and fittings in toilets. In addition, failure to apply second coats&#xD;
of paint to walls was deemed a problematic issue. Typical surface/appearance defects were found to include floor or wall unevenness, stains,&#xD;
mess, and small cracks and marks, primarily caused by lack of protection. In areas where fixtures, fittings, and finishes were of a similar&#xD;
nature, such as the kitchen and bathroom, defect types also arose. Determining the location, subcontract, and element where defects occur in&#xD;
residential buildings can provide invaluable knowledge about areas where builders are likely to make errors or mistakes or take deliberate&#xD;
shortcuts during construction. Thus, emphasis on quality control and supervision of subcontract trades, especially in the identified areas, and&#xD;
during the final stages of residential construction, are critical to ensure that defects are reduced.</description>

      <description>Title: Tecnología para la sostenibilidad: ¿conveniencia o necesidad
Authors: Esquerra, Pere; Planas Rodríguez, Carla; Gallostra, Juan; Túnica, José
Abstract: La Comunidad Europea editó la Directiva 92 sobre la eficiencia Energética de los Edificios en la que mostraba su preocupación por el aumento imparable de los consumos por causa del aire acondicionado. La eficiencia de&#xD;
los equipos puede ser una de las repuestas, pero el uso de recursos naturales que no consuman energía debe tenerse en cuenta también, aplicando las reglas de la bioclimatización, que en algunos casos pueden ser las únicas&#xD;
aplicables cuando la energía sea un bien escaso. En cualquier caso en los hospitales es necesario tener un control&#xD;
de las condiciones climáticas, sean naturales las fuentes o no. La Tecnología para la Sostenibilidad quier dar&#xD;
respuesta a la problemática.</description>
