No full textIn the framework of methods and techniques for reducing energy consumptions and ecological impacts in the construction sector, pre-cast building components are acknowledged as valuable solutions meeting high requirements of economic, social and environmental sustainability. As a matter of fact, the design standardization, the fabrication in factories and the mechanization of on-site installation techniques might overcome some shortcomings of cast-in-place systems, including low field productivity, unreliable quality, high resource exploitation and waste, as well as frequent safety accidents. Moreover, their energy-environmental quality might be even improved, whenever a circular economy approach is applied to the supply chain. In this regard, the paper is focused on precast Expanded Polystyrene Insulation - Reinforced Concrete (EPS-RC) walls, whose construction layout and details were previously patented by the authors, and it concerns the feasibility assessment of using recycled EPS particles in the concrete mixtures, in order to improve the lightness, insulation and carbon footprint of the conglomerate. To this end, several mixtures were formulated with partial or total replacement of the volume of sand aggregates with EPS tailings and tested with regard to thermal properties and mechanical strength, in order to identify whether the materials could be considered structural or non-structural, as well as normal or lightweight, according to the normative codes and regulations. The proposed approach is meant to optimize both the quality and versatility of the building component and the efficiency of the production processes, taking into account that the EPS by-products, currently disposed of, would turn into a resource with beneficial effects on waste management and materials exploitation

No full textDifferent risk conditions affect the Built Environment (BE), that is a network of buildings, infrastructures, open spaces, and users. They can appear in an unpredictable and quick manner (Sudden-Onset Disas-ters-SUODs, e.g., earthquakes, terroristic attacks), or emerge gradually over time (SLow Onset Disasters-SLODs, e.g., climate-change related, pollution, heat waves).
Existing BEs, especially historical ones, are generally characterized by a poor resilience level, as shown by many recent disasters. Increasing the BE solutions means to move towards: (1) mitigation strategies focused not only on the buildings, but also on the neighboring network elements, and, mainly, open spaces; (2) the inclusion of user-centered factors (exposure, vulnerability, behaviors) in risk assessment and reduction; (3) SUODs-SLODs combination, pursuing a multirisk perspective also in case low probability-high impact events coupling; (4) supporting stakeholders’ assessment with “what if” approaches for multirisk simulation-based evaluations, and with quick preliminary assessment approaches also based on BE typological analysis; (5) exploiting users/stakeholders’ training to increase resilience from the bottom. The BE S2ECURe – “(make) Built Environment Safer in Slow and Emergency Conditions through behavioUral assessed/designed Resilient solutions”, supported by MIUR in the context of the Italian PRIN, adopts these standpoints to develop methods, tools, and guidelines for BE resilience assessment, risk-mitigation strategies design, and users’ risk awareness increase, by using multirisk and user-centered criteria. This work offers an overview of the main project results, focusing on risk assessmentand mitigation issues in BE typologies (BETs), since they can represent archetypes of real worldbased scenarios. Thus, the BET modelling and multirisk behavioural-based assessment could be the basic point for supporting designers and stakeholders to tailor risk mitigation strategies (i.e. architectural interventions, safety management, training via Virtual and Augmented Reality techniques) depending on the case studies specificities
