From lab to industry: Scaling up green geopolymeric mortars manufacturing towards circular economy
2021
Abstract Construction is nowadays considered an extremely energy intensive industry and one of the main sources of environmental pollution in the world. Therefore, the research and the development of novel energy-saving manufacturing processes and sustainable construction materials is more than ever urgent and challenging. This paper aims at identifying the industrial process for the production of novel geopolymers to be used as a greener substitute for cement, especially the Portland one, widely used for structural applications to significantly reduce the environmental impact of the construction industry. Here, the materials sustainability and the manufacturing process are improved by valo…
Unexplored alternative use of calcareous sludge from the paper-pulp industry in green geopolymer construction materials
2020
Abstract Calcareous sludge is an alkaline waste produced by the paper pulp industry that is commonly disposed of in land-fill. However, recent studies and the European regulations discourage such practice. This work investigates an alternative and innovative way to recycle and reuse this waste, as filler, in the production of green geopolymeric mortars intended for applications in construction. This is the first time that this calcareous sludge is used to produce novel waste-based materials, in both construction and geopolymer technology. The novel alkali-activated mortar also uses biomass fly ash – another slightly investigated waste stream – to substitute the metakaolin (70 wt% substituti…
Il caracol quadrato in Sicilia (XVI secolo)
2022
Square spiral staircases appear in Sicily during the 16th century in different contexts and for different purposes. This contribution focuses on two case studies at the “opposite poles” of a casuistry that shares the common characteristics of suspended ramps revolving within a square masonry box around a central void. By analysing these cases we find a probable link with models from Spain. At the same time, they demonstrate a common descent from a constructive culture rooted in the Spanish and Mediterranean stereotomic experience of the early modern age.
Earthquake-resistant construction techniques in Italy between 1880 and 1910: alternatives to reinforced concrete
2017
The series of earthquakes that struck Italy between the late nineteenth century and the first decade of the twentieth century spurred a lively debate about earthquake-resistant buildings that, through the influence of foreign experience, resulted in specialised literature and competitions that gave rise to a series of interesting patents. Innovative construction solutions for seismic areas were largely developed after the earthquake that struck the cities of Messina and Reggio Calabria in 1908, alongside the parallel advances in reinforced concrete. New earthquake-resistant construction solutions were based on a reassessment of traditional construction methods that used bricks, timber or me…

London 2012. Sustainable Design, Delivering a Games Legacy è una monografia pubblicata nel gennaio del 2012, dalla casa editrice americana John Wiley & Sons Inc., e non ancora radotta in italiano. In quest’opera l’autrice, Hattie Hartman, architetto e urban designer, formatosi alla Harvard University e al Massachusetts Institute of Technology, scrive alla luce dell’esperienza maturata come Sustainability editor nel settimanale inglese “The Architects’ Journal”, edito dal 1896 a compendio del famoso mensile internazionale “The Architectural Review”, proponendoci una lettura sulla sostenibilità dei lavori per le Olimpiadi di Londra 2012.
Architectures en vertige et « topographie » du personnage chez Julien Green
2018
L’architettura è senza dubbio uno degli assi fondamentali attorno al quale si dispiega l’immaginario di Julien Green, la cui opera è ricca di dimore, castelli, camere, biblioteche, spazi urbani. Attraverso l’analisi di tre romanzi (Mont-Cinère, Adrienne Mesurat, Minuit), l’articolo si propone di mostrare, per mezzo del riferimento metodologico ai Séminaires e agli Écrits di Lacan, che gli spazi architettonici rappresentati assumono nello scrittore una dimensione trascendente che realizza lo slittamento dagli spazi reali alla topologia soggettiva dei personaggi. Architecture is undeniably one of the fundamental axes around which the imagery of Julien Green unfolds, whose work is full of hous…
MOBILE MAPPING FOR CULTURAL HERITAGE: THE SURVEY OF THE COMPLEX OF ST. JOHN OF THE HERMITS IN PALERMO (ITALY)
2023
Abstract. During the 11th and 12th century, the Arab-Norman architectural style characterized the most beautiful and important Cultural Heritage buildings in Sicily, and especially in Palermo (Italy). The relevance of these monuments is highlighted by their inclusion in the UNESCO World Heritage Sites List in 2015. For many years, the University of Palermo has been studying and documenting several Arab-Norman cultural assets, and in particular, the complex of St. John of the Hermits in Palermo (Italy). A first detailed 3D survey of the main structures of this complex was carried out using a terrestrial laser scanner while the 3D survey of the entire complex was made using a Mobile Mapping S…
Timoteo Calvo Ibarra (1799-1879). Un arquitecto valenciano durante el reinado de Isabel II.
2015
In the complex scene of valencian architecture of 19th century, Timoteo Calvo Ibarra should be considered as one of the most representative authors. In his designs and interventions, such as the Literary University, the construction of new Cathedral’s Altarpiece, they are apparent the peculiarities of the first Historicism, coincident with Isabelline period. In this first stage of historicism, the homogeneity and guarantee of good taste that classicism provided was no longer valid as unique option and it will be simultaneous with romantic architecture represented by the first historicist experiences, which will conclude with the burst onto the scene of the eclecticism in the restoration of …
Leon Battista Alberti archeologo
2007
Il Convegno rientra nelle celebrazioni ufficiali per il VI centenario della nascita del grande umanista del Quattrocento italiano. Il contributo, unico nel panorama della critica albertiana, mira a mettere a fuoco le propensioni antiquarie e archeologiche dell'Alberti, inquadrando questi interessi nel vasto panorama della cultura antiquaria del Quattrocento italiano. Ne rivela anche aspetti significativi nel suo concreto operare come architetto e ne ricostruisce le pratiche della ricerca sui monumenti antichi di Roma e di molte altre parti dell'Italia.
