The aim of this paper is to research new thermally-efficient concrete walls, analyzing the mechanical behavior of a self-compacting concrete to manufacture an uncoated solid structural panel, with the incorporation of a micro-encapsulated phase change material as additive. Different dosages are tested and mechanical properties of the product obtained from the molding of concrete specimens are evaluated, testing mechanical compressive strength, slump flow, and density. The results reveal the optimum percentage of additive in the mixture that enables compliance with the technical specifications required by the product to be manufactured. A test is also performed for measuring the thermal conductivity for the optimal sample obtained and it evidences the reduction thereof.

The research focuses on the use of recycled aggregate (RA), from waste pieces generated during production in precast plants for self-compacting concrete (SCC) manufactured with a double sustainable goal: recycle manufacturing waste (consumption) and improvement of the thermal properties of the manufactured product (energy efficiency). For this purpose, a mechanical study to ensure technical feasibility of the concrete obtained has been conducted, as well as a thermal analysis of recycled SCC specimens of 50 N/mm² resistance, with different RA doses (0%, 20%, 50% and 100%). The main parameters that characterize a SCC in both states, fresh (slump-flow) and hard (compressive strength), have been tested; also, a qualitative analysis of the thermal conductivity using infrared thermography (IRT) and quantitative analysis with heat flow meter at three temperatures 20 °C, 25 °C and 30 °C have been performed. The results suggest the existence of two different thermal behaviors: concretes with 0% and 20% of RA, and on the other hand concretes with 50% and 100% of RA. It has also demonstrated the validity of the IRT as sampling technique in estimating the thermal behavior of materials having reduced range of variation in parameters.

For several decades, in our country, the engineering schools have trained numerous engineers, with great technical ability but without any professional experience or any current contact with Industries. They have to find their first job by themselves and by their chance, without any kind of help or orientación. Because of the crisis that currently exists in Spain and also, in several countries worldwide, it is even harder, for the postgraduates, acquires their first contact with job-market. From our Research Group “INARdesign” belonging to the School of Industrial Engineering (University of Vigo), we have participated in a research Project, in which, we try to develop a model, consisting of the implementation of a system of Mentoring, between the graduate, the College, the employment and also the industry, so that their actions synchronized, facilitates the incorporation of postgraduates into the job-market. It seems logical that the University, the birthplace of these postgraduates, who has dedicated lot of time to their training, takes one step more and assume a new challenge: the link between universities and the job market This, it could be done, creating figures as Mentor at the University and as Tutor at the Industry, in this case the Tutors shall be from the Technical Unit of the Universities or any other scientific or nonprofit Companies and create a collaboration model to facilitate the student's first contact with daily problems on the job-market Once, this new model has been developed, also it has been implemented through several pilot projects in order to validate it. In order to do it, it has been suggested several lines of performances, regarding important matters nowadays; in this case, it is proposed to the University of Vigo, some themes called energy efficiency of existing buildings.
