Effect of water on the transmittance of glass plates with eroded surfaces

Chemical durability of soda-lime glass in aqueous acid solutions

“…In turns, the craters grow and become interconnected in such a way that they form a continuous altered, opaque corrosion crust. In early research works, the attention was focused on the phases formed at the surface of weathered glasses, the so-called "hydrated silica" layer and calcium/potassium sulphates and carbonates may be formed [5,12,14]. A description of the corrosion process was proposed but without trying to consider the modification of the glass network itself in relation with the leaching of K + , Na + and to some extent Ca 2+ ions.…”

“…In order to lower the melting temperature (~2000 0 C) of the pure silica glass, sodium oxide is added to the glass melt. The reaction between silica and sodium oxide turns silica into silicate and reduces the melting temperature to a value below 1600 0 C since the polymeric silica chains are interrupted according to the reaction (1) [1][2][3][4][5][6][7][8].…”

“…The corrosion is a chemical phenomenon which can affect the quality of a glass surface, since the glass can fail as a result of its continuous exposure to a corrosive environment. If a glass surface is put into contact with water or with any aqueous solution, it may chemically react with this medium and this chemical exchange may spread all over the surface of the glass, hence causing some undesirable effects, particularly a change in mechanical strength as well as the transmittance [5].…”

Structural characterisation of adaptive facades in Europe – Part I: Insight on classification rules, performance metrics and design methods

“…As far as these conventional materials are used for dynamic skins rather than static facades, major structural design issues are expected to derive from their thermo-physical and mechanical performance under long-term and/or cyclic loads, including fatigue phenomena, material degradation due to environmental conditions, temperature variations, etc. Specific studies are hence required for structural assessment purposes ( [36][37][38][39][40], etc.). According to recent research challenges, adaptivity and flexibility in facades can be achieved by means of innovative use of conventional materials, like thin glass panels allowing for cyclic deformations (see for example Fig.…”

Influence of the normal load of scratching on cracking and mechanical strength of soda-lime-silica glass

“…Scratching is then of paramount interest because it affects the strength [1]. Knowing the scratch shape permits correlating the response of the material, under controlled contact solicitations, to the physical mechanisms that govern the nature of the damage [2][3][4][5][6][7][8][9].…”
