“…The large portion of glassy phase obtained at this stage might be attributed to high percentage of RSLG incorporated and the fact that mullite growth and glassy phase are more pronounced at higher sintering temperature. This phenomenon has also been reported by previous authors …”

“…7 In view of this, extensive works are ongoing at harnessing these wastes into ceramic production systems. Several authors have reported on the use of waste glasses as substitute to feldspar in ceramic components, [7][8][9][10][11] while the only work on incorporation of discarded sanitary wares into its own composition as substitute to quartz was investigated by Ana et al 7 However, no work has been conducted on incorporation of both discarded sintered sanitary wares and waste soda-lime glasses as postsintered wastes to substitute for quartz and feldspar respectively in sanitary ware body formulations. In this regard, this work aims developing low-cost sanitary bodies with better technical properties for domestic applications.…”

Due to high consumption of conventional materials such as quartz and feldspar in most ceramic products processing, the recent practice has been targeted at exploration and utilization of some industrial wastes with similar characteristics to solely or partially replace these conventional materials to reduce cost of production, and serves as a means of solid wastes management. In this regard, this work aims at incorporating postsintered wastes as partial and sole alternatives to quartz and feldspar in the production of vitreous sanitary ceramics. Vitreous sanitary ware bodies containing discarded sanitary wares and waste soda‐lime glasses as substitute to quartz and feldspar respectively were prepared using slip casting process. Several samples measuring 120 × 50 × 10 mm were cast, left to dry at ambient temperature for 24 hours followed by oven‐drying at 105°C for another 12 hours. The cast samples were then subjected to sintering at temperatures of 1150 and 1200°C, respectively, and then soaked for 90 minutes. Physico‐mechanical, phase, and structural evaluations were carried out to assess the performance of the vitreous sanitary bodies. The results showed that samples containing postsintered wastes displayed better physical, mechanical, and structural properties, while the chemical compositions of the prepared samples showed close similarity to standard Twyford sanitary ware. However, better properties were observed for samples sintered at 1200°C which might be attributed to high vitrification at elevated temperature.

“…Several compositions of porcelain stoneware have been reported [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. They commonly consisted of clay 40 -75 %, feldspar 0 -18 %, and quartz 27 -50 % [3].…”

In this work, the effect of pore foaming agents (polymethyl methacrylate, PMMA) on the densification characteristics as well as mechanical and thermal properties of sintered porcelain samples was investigated. The influence of the PMMA content (0-20 wt. %) and sintering temperature (1000-1300 °C) were also studied. The result showed that the incorporation of PMMA in porcelain bodies led to a decrease in the density, while the porosity increased with an increase in sintering temperature. At 1300 °C, the bulk density and porosity of porous porcelain samples with PMMA additions (5-20 wt. %) were in the range of 1.91-2.23 g•cm-3 and 1.3-17.2 %, respectively. The flexural strength of the porous porcelain samples prepared by adding 5-20 wt. % PMMA and sintering at 1300 °C was in a range of 36-56 MPa, which is higher than the minimum strength values (35 MPa) of ISO 13006 standard for ceramic tiles. The thermal conductivity of porous porcelain is a function of the sintering temperatures. The increase in sintering temperature had a positive effect on the thermal conductivity of ceramic samples, because the thermal conductivity decreased significantly with increasing porosity levels. The addition of 20 wt. % PMMA in porcelain samples sintered at 1300 °C reduced the thermal conductivity up to 34 % while maintaining acceptable flexural strength values (~ 36 MPa). Thus, it is possible to use these porcelain samples as ceramic tiles in order to enhance the thermal resistance of building materials.

“…Similar findings were also reported by others, demonstrating that CWG could be used as a partial alternative to feldspar in porcelain sanitary ware. [112][113][114][115][116][117][118][119][120][121] Lin 122 studied the behavior of CWG and white clay (thin film transistor-liquid crystal display) as a raw material for the manufacture of ceramic tiles. Tile samples were prepared by adding 0%-50% CWG in the ceramic mixture.…”

Each year, hundreds of thousands of tons of industrial wastes are being stockpiled, landfilled, and disposed of in storages occupying large areas of land that would otherwise be available for productive use. Recycling of such wastes is now becoming of urgent global interest due to an increasing population, the rise in anthropogenic activities, and the need for more efficient resource and waste management systems.Among many wastes, the generation of glass is dramatically increasing, particularly in the municipal, industrial, and construction sectors. In civil engineering, in general, crushed waste glass has been mainly investigated as a substitute for sand and finegrained aggregate in concrete production. In geotechnical engineering, in particular, the application of glass wastes is mainly limited to road pavements or as an additive to different soils for subgrade improvement. While glass wastes are relatively inert and potentially offer several opportunities for recycling as a substitute for diminishing and increasingly expensive sand supplies, their potential use yet remains relatively under-researched. This paper systematically reviews the current status of knowledge on the use of glass wastes in various civil engineering applications and discusses the suitability assessment of waste glass for use as a sustainable alternative to traditional civil engineering materials.
