“…Before use, bottom ash has to be oven dried and ground in order to improve homogeneity. It has been established that it is possible to manufacture glass-ceramics from bottom ash and from bottom ash mixed with other wastes, namely glass cullet and steel fly ash [151,[154][155][156][157][158], and this will be considered in more detail here.…”

“…Cheeseman and co-workers [155,156] have concentrated on producing glass-ceramics from bottom ash, having quartz, calcite, gehlenite and hematite as the main crystalline phases, without the use of any additives. The bottom ash was subjected to a thorough homogenisation process involving wet ball milling, filtering, drying, grinding and finally sieving through 150µm sieve;…”

“…A maximum density of 2.6g/cm 3 was obtained at the optimum sintering temperature. The main crystalline phase(s) were reported to be diopside [155] and diopside and wollastonite [156].…”

Glass-ceramics: Their production from wastes—A Review

2006

Glass-ceramics are polycrystalline materials of fine microstructure that are produced by the controlled crystallisation (devitrification) of a glass. Numerous silicate based wastes, such as coal combustion ash, slag from steel production, fly ash and filter dusts from waste incinerators, mud from metal hydrometallurgy, different types of sludge as well as glass cullet or mixtures of them have been considered for the production of glass-ceramics. Developments of glassceramics from waste using different processing methods are described comprehensively in this review, covering R&D work carried out worldwide in the last 40 years. Properties and applications of the different glass-ceramics produced are discussed. The review reveals that considerable knowledge and expertise has been accumulated on the process of transformation of silicate waste into useful glass-ceramic products. These glass-ceramics are attractive as building materials for usage as construction and architectural components or for other specialised technical applications requiring a combination of suitable thermo-mechanical properties.

“…This is a hazardous material and there has been much less work reported on sintering IBA as this is generally much less problematic (Bethanis et al, 2002a;Cheeseman et al, 2003). It has been mixed with glass cullet and a range of other industrial wastes and used as a raw material for the production of glass-ceramics (Barbieri et al, 2000a(Barbieri et al, , 2000bFerraris et al, 2001;Romero et al, 2001).…”

“…Previous work has shown that higher temperatures and longer dwell times are needed to significantly reduce metal leaching from sintered IBA (Bethanis et al, 2002a(Bethanis et al, , 2002b. There are however, significant differences in the leaching behaviour of different metals.…”
