“…Its erosive resistance was found to be a function of the abrasion mass and the time and temperature used in the toughening process (Butaev and Vygorka 1987). Chemical toughening was found to offer a slight improvement over the performance of annealed glass when exposed to erosive action for small masses of abrasive medium, in terms of glass mass loss, roughness and optical transmission but the strength of glass was assessed (Bousbaa et al 2003).…”

Glass is known for its excellent durability, but the strength of glass is very sensitive to the characteristics of its surface, which is known to accumulate damage during its service life. There is however, a lack of strength data on weathered or aged glass, particularly on thermally or chemically treated glass. In this study a carefully calibrated sand trickling test is used to produce surface damage equivalent to erosive action of 20 years of natural weathering on different types of glass: soda-lime-silica annealed, soda-limesilica fully toughened and aluminosilicate chemically toughened. The soda-lime-silica glass specimens are tested destructively in their as-received and artificially aged form in a conventional coaxial double ring setup, while the alumino-silicate chemically toughened specimens are tested in an improved coaxial double ring set-up. Fractography is subsequently used to identify and measure the critical flaw size on each specimen. The strength data are analysed statistically and the design strengths for each glass type are obtained. It is found that all glasses suffer a loss in strength after artificial ageing, with fully toughened glass providing the best post-aged performance. It was also found that Electronic supplementary material The online version of this article
