Bristogianni, T. (author)Cast glass has great application potential in the architectural realm, yet, despite its possibilities and attractiveness, designers, engineers and developers are, from an early design stage, hesitant to employ it; the limited available and craft-based manufacturing facilities, the questionable quality of the product, the missing engineering data...doctoral thesis 2022

Damen, J.T.W. (author), Oikonomopoulou, F. (author), Bristogianni, T. (author), Turrin, M. (author)Up to now, fabricating cast glass components of substantial mass and/or thickness involves a lengthy and perplex annealing process. This has limited the use of this glass manufacturing method in the built environment to simple objects up to the size of regular building bricks, which can be annealed within a few hours. For the first time,...journal article 2022

Bristogianni, T. (author), Oikonomopoulou, F. (author)This paper presents the casting of volumetric glass components from glass waste as an alternative glass-recycling approach. The approach is characterized by its flexibility to accommodate a variety of compositions and ability to yield volumetric (solid or thick-walled) glass products that can tolerate higher contamination rates without a...journal article 2022

Justino de Lima, C.L. (author), Aldinger, Brandon (author), de Haan, Peter (author), Bristogianni, T. (author), Veer, F.A. (author)Among the environmental factors affecting glass weathering are humidity, exposure time, temperature, and the presence of pollutants in the atmosphere. Notwithstanding that the weathering produced depends on numerous factors, the important weathering effect of high humidity may be specifically mitigated by using a good chemical composition for...journal article 2022

Oikonomopoulou, F. (author), Bristogianni, T. (author)Cast glass is a promising, three-dimensional expression of the material for architectural and structural applications, particularly for the creation of all-transparent, self-supporting structures and envelopes. Typically applied in the form of solid blocks, cast glass components can be used as repetitive units to comprise fully-transparent, cast...journal article 2022

Bristogianni, T. (author), Oikonomopoulou, F. (author), Veer, F.A. (author), Nijsse, R. (author)The emerging interest in the architectural applications of cast glass components reveals a knowledge gap on the mechanical properties of cast glass. Apart from its chemical composition, cast glass is characterized by its manufacturing history and thermal profile, often inheriting a set of defects that define its properties. The role that...journal article 2021

Recycled Glass Mixtures as Cast Glass Components for Structural Applications, Towards SustainabilityAnagni, G.M. (author), Bristogianni, T. (author), Oikonomopoulou, F. (author), Rigone, Paolo (author), Mazzucchelli, Enrico Sergio (author)The problem of sustainability represents one of the most important issues that the world has to face nowadays, not only in terms of energy consumption and of the consequent CO2 emissions, but also in terms of material waste streams that end in landfill. 38 million tons of glass waste are produced every year in the European Union and new targets...conference paper 2020

Yet, this glass is potentially a valuable resource for casting robust and aesthetically unique building components. Exploring the potential of this idea, different types of non-recyclable silicate glasses are...journal article 2020

However, apart from glass bottles, unfortunately, that a large amount of glass will disappear into landfills. This large quantity of unrecycled glass indicates that there is a large potential in upgrading...conference paper 2020
