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…
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…

GIOVANNI CARBONARA. ARCHITETTURA D'OGGI E RESTAURO: UN CONFRONTO ANTICO-NUOVO
2012
Architettura di oggi e restauro dell'antico sono temi largamente dibattuti per quanto riguarda le modalità di approccio. Non esistono leggi a priori o regole da seguire, ma si è sempre cercato di stabilire parametri e categorie per uniformare le proprie scelte. All'interno di tale panorama inevitabilmente si delineano correnti di pensiero diverse, talvolta anche contrastanti, caratterizzate ognuna da un diverso modo di interpretare il rapporto tra l'antico e il nuovo. Proprio all'interno di tale dialettica si inserisce il pensiero di numerosi architetti, fra cui quello di Giovanni Carbonara, che, attraverso il presente testo, ha voluto presentare una variegata rassegna delle possibili modal…
Performance Analysis of Innovative Vacuum Insulation Panel
2013
Thermal insulation has become one of the central themes in energy behavior improvement. The use of insulating materials, from the thermal and hydrothermal aspect, allows the reduction of the heat transfer in each of the technical elements increasing their thermal inertia. Even if the research has led to the use of innovative materials with high values of thermal insulation, one of the main problems, which is difficult to resolve, is the thickness of the building envelope to reach levels of transmittance that can allow considerable savings of energy and CO2 emissions. With this objective the VIP (Vacuum Insulation Panel) technology in building applications is an innovative solution to obtain…
Green geopolymeric concrete using grits for applications in construction
2018
Abstract This work investigates the production a green geopolymer-based concrete for a sustainable construction material using biomass wastes from a kraft pulp industry: fly ash (as main alumina-silicate source) and grits (as aggregate). Moreover, a simple, reproducible, ambient temperature, and low-cost manufacture is followed. Mix design aims to maximize wastes incorporation and optimize the mechanical performance. Preliminary tests indicate that the used wastes may be successfully employed to produce green geopolymeric concretes with satisfying mechanical performance (up to 18 MPa), according to the European standards. Furthermore, they represent a viable solution to reduce the environme…
Margini e interstizi vegetati per una città resiliente
2021
La mancanza di vegetazione all’interno delle nostre città e, soprattutto, dei centri storici determina oggi, alla luce dei cambiamenti climatici in corso, notevoli problematiche tra le quali vanno annoverate – tra quelle più gravi – l’impossibilità di contrastare efficacemente le ondate di calore, sempre più frequenti in ambito Mediterraneo, con conseguente aumento dei consumi energetici degli edifici dovuti alla necessità di garantire il comfort indoor e l’incapacità di rallentare il deflusso delle acque meteoriche che a causa degli eventi di pioggia estremi e dell’impermeabilità dei suoli rendono sempre più inefficaci i sistemi di drenaggio urbano esistenti. L’utilizzo della vegetazione c…
