“…The industrial waste (IW)-V product waste glass (WG) can be used as a SCM or a filler in a variety of applications, including ultra-lightweight fiber-reinforced concrete (ULFRC) and burned bricks [ 108 , 109 , 110 , 111 , 112 , 113 , 114 ]. Additional applications include glass-reinforced doors, concrete building maintenance, and polymer concrete that cures quickly [ 115 , 116 , 117 , 118 ].…”

Polymer composites have been identified as the most innovative and selective materials known in the 21st century. Presently, polymer concrete composites (PCC) made from industrial or agricultural waste are becoming more popular as the demand for high-strength concrete for various applications is increasing. Polymer concrete composites not only provide high strength properties but also provide specific characteristics, such as high durability, decreased drying shrinkage, reduced permeability, and chemical or heat resistance. This paper provides a detailed review of the utilization of polymer composites in the construction industry based on the circular economy model. This paper provides an updated and detailed report on the effects of polymer composites in concrete as supplementary cementitious materials and a comprehensive analysis of the existing literature on their utilization and the production of polymer composites. A detailed review of a variety of polymers, their qualities, performance, and classification, and various polymer composite production methods is given to select the best polymer composite materials for specific applications. PCCs have become a promising alternative for the reuse of waste materials due to their exceptional performance. Based on the findings of the studies evaluated, it can be concluded that more research is needed to provide a foundation for a regulatory structure for the acceptance of polymer composites.

“…In addition, the fluxing action by the alkali activation from network-modifying components such as CaO may also contributes in the increase of densification of sample and promoting the growth of wollastonite crystal [10]. However, if the cullet content is further increased beyond 55 wt %, the density starts to decrease probably due to the Si sp 3 electronic configuration that forms 3-dimensional geometric silicate structure, which is considered to be apt to form viscous layer, thus more effective in retaining gases inside the ceramic matrix, which consequently reducing the viscosity and leading to a lower particle density [6,9,11,12]. From Figure 1, it also found out that the density decreases as the sintering temperature is increased.…”

“…Naturally, it is reported that the optimum composition of wollastonite is 48 wt% CaO and 52 wt% SiO 2 with some trace elements like manganese, potassium, magnesium, aluminum, iron, and sodium [4]. Few studies have been reported on wollastonite glass-ceramic made from various of waste such as mixtures of automobile waste glass and waste shell, waste glass and coal fly ash, window glass powders and F-type coal fly ash [3,[5][6][7]. The major mineral resources of these wastes are mostly SiO 2 , Al 2 O 3 , and CaO which could promote the formation of ceramic.…”

Lightweight glass-ceramic from waste material consists of (x) paper ash-(80-x) cullet-20 Kaolin clay where (10 ≤ x ≤ 30 weight %) are sintered at 900°C, 1000°C and 1100°C using conventional solid-state reaction technique. The influence of composition and sintering temperature on density, crystalline phase, porosity and surface pore morphology was studied. The crystal symmetry, space group and unit cell dimensions which are executed from XRD data are analyzed using SmartLab Studio II Powder XRD software. Meanwhile, the lattice parameter, cell volume, theoretical densities and porosity were estimated by Rietveld refinement method. The results reveal that all parameters exhibit a temperature-dependent character, as the temperature is increased, the density decreases and porosity increases due to bloating effects. It is also found out that the glass-ceramic compose of 25 paper ash −55 cullet-20 Kaolin clay, sintered at 900°C exhibits an optimum characteristic of the sample density reached optimum because of vitrification between cullet glass, paper ash and kaolin clay to form liquid phase which promotes adhesion and polymerization. It is observed that the surface morphology of the sample is affected by the crystallization process during sintering.

Several sustainable ceramic composites were prepared from 3 – 7 wt.% of hazardous toner waste, 0 – 42% of spent foundry sand, 0 – 25% of galvanic glass waste, and 30 – 93% kaolin clay. Developed composites were sintered at 1100°, 1150°, 1200°, 1250°, and 1275°C. The ceramics’ flexural resistance values reached up to 12.29 MPa, linear shrinkage varied between 2.99 and 11.20 %, and water absorption – between 19.90 and 10.85%. The investigation of the ceramics structure formation processes using the X-ray diffraction, X-ray fluorescence, SEM, EDS AAS, and lased micro-mass analyze methods showed the synthesis of glassy structures with the inclusion of mullite and cristobalite crystalline structures. The analysis of the chemical composition of the gases emitted during ceramics firing at 1,275°C by the atomic absorption spectroscopy method, as well as the analyses of solubility and leaching of metals from ceramics, showed that the developed composites and technology were in full compliance with Brazilian sanitary standards. The results of the conducted research allow to decrease environment pollution by using hazardous industrial toner waste, galvanic glass waste and spent foundry sand as valuable raw materials to produce sustainable ceramics with high values of mechanical, physical and chemical properties.
