SUMMARY:PhDTalks | A methodology to assess the evolution of mechanical performance of UHPC as affected by autogenous healing under sustained loadings and aggressive exposure conditions
DESCRIPTION:La serie di seminari PhDTalks riprende con il primo appuntamento del 2023 che si terrà martedì 4 Aprile\, dalle 17:15 alle 18:30 CET nell’aula Fassò (Edificio 4a – Piazza Leonardo da Vinci\, 32). \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nIn questa occasione\, il seminario sarà condotto da Marco Davolio e il titolo dell’intervento sarà “A methodology to assess the evolution of mechanical performance of UHPC as affected by autogenous healing under sustained loadings and aggressive exposure conditions“. \nSarà anche possibile seguire l’evento online accedendo alla stanza WebEx. \nAbstract: \nThis study investigates the evolution of the performance of an Ultra-High Performance Concrete (UHPC) under simultaneous action of sustained loading and aggressive environmental exposure. UHPC mixes were investigated containing different functionalising micro- and nano-scale components to promote autogenous self-healing. In order to assess the healing capabilities in the different multi-action scenarios and the evolution of the mechanical response of the material over time\, a tailored methodology was implemented\, including non-destructive and destructive tests performed all along the scheduled exposure/healing times up to 12 months. In particular\, an innovative set-up was designed to reproduce on the specimens the sustained flexural loading conditions a structure undergoes during its service life; the load was applied simultaneously with each of the three selected different exposures\, to simulate the chloride and sulphate aggressive environments\, besides a reference one. Multiple indices were defined to quantify the self-healing efficiency\, which were further calibrated against experimental microscope crack observation as well as cross correlated with each other\, as a further proof of the reliability of the proposed methodology. Two nominally identical specimens were tested for each condition\, the first in four-point bending and the second in direct tension. To compare the results\, a simplified five-point inverse analysis was adapted for beams with different slenderness\, providing a quadrilinear constitutive law derived from the structural flexural behaviour of four-point bending tests. The results confirmed the material durability\, especially in the cracked state\, through its capacity of sealing the cracks and restoring original properties in short periods and preserving its load bearing capacity\, thus providing solid argument for UHPC as the ideal candidate material for highly durable and sustainable structural applications in aggressive scenarios. \nSpeaker’s bio \nMarco is a Ph.D. Candidate in Structural\, Seismic\, and Geotechnical Engineering (38th cycle) at Politecnico di Milano. He has BSc and MSc in Building Engineering and experience as a structural designer in a professional studio. Marco is currently developing carbon capture and uptake strategies for cementitious materials to reduce the environmental impact of the concrete construction industry. He is also cooperating with international companies such as Cemex and Energy Vault for the experimental fatigue characterization of Steel Fibre Reinforced Concretes and studying self-healing of Ultra-High Performance Concretes in the framework of European projects.

SUMMARY:The role of Social Hotspot analysis in waste management: assessing sectoral social impacts for a better understanding of social risks
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 18 Aprile nell’aula 2.1.3 (Edificio 2)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Giuseppe Cecere condurrà un seminario dal titolo “The role of Social Hotspot analysis in waste management: assessing sectoral social impacts for a better understanding of social risks”.\nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract: \nSocial Life Cycle Assessment (S-LCA) is a methodology developed to assess the negative and positive social impacts of products and services\, along their life cycle. The new Guidelines for Social Life Cycle Assessment of Products together with the Methodological Sheets\, published in 2021 by the United Nations Environment Programme\, provide a roadmap to help stakeholders in the assessment of social impacts of products’ life cycles. However\, applications are hindered by the high sensitivity of the data under investigation and the relative novelty of the methodology. The Social Hotspot analysis allows\, as a preventive measure and through secondary data\, to identify the social issues that should be focused on during risk assessment. This type of analysis that allows the identification of the most sensitive themes can be used as a first step in the application of the S-LCA. In the waste sector\, the application of methodologies to assess social impacts could be particularly useful. Waste management facilities often suffer from strong protests both during construction and operation. Phenomena such as Not In My Backyard (NIMBY) syndrome and Locally Unwanted Land Use (LULU) are very common during the planning and implementation of this type of facilities. Most of these objections are often due to a bad communication approach on both sides and a denial of potential social and environmental impacts by plant operators. Using the Product Social Impact Life Cycle Assessment (PSILCA) database\, this study aims to identify the social hotspots that characterise the waste and wastewater management industry sector in the Italian context. In order to create a suitable reference scale\, the results for Italy were compared with the results of several European countries. The result is an industrial sector risk assessment\, calibrated on the European context\, which can be used as a first step in the evaluation of subcategories and indicators to be prioritised in the assessment of social impacts in the context of waste and wastewater management facilities. \nSpeaker’s bio: \nGiuseppe is a PhD Candidate in Environmental and Infrastracture Engineering (37° cycle) at Politecnico di Milano. Since 2020\, he has been working with the AWARE research group.  For his PhD project\, he is working on the application of Life Cycle Thinking methodologies to the waste management sector.  He holds a Master’s degree from the University of Padua and a Bachelor’s degree from the University of Naples ‘Federico II’.
