“…As a result, the particles may be packed more uniformly, which may also reduce the porosity of the tile. 48,49 The same has been concluded by Darolt et al 33 and Ishizaki et al .58 The effect of raw material composition on the processing sequence demonstrates how the proposed simulation methodology applies to the entire manufacturing line and is adaptable to variations in raw material conditions. In Figure 5, color maps display the determined sintering temperatures for different compositions based on the concentration of the compounds.…”

“…Additionally, the surface energy of talc particles is relatively low, which can lessen the surface tension between the particles in the formulation of the tile. As a result, the particles may be packed more uniformly, which may also reduce the porosity of the tile 48,49 . The same has been concluded by Darolt et al 33 .…”

“…These properties make talc an important additive in the ceramic tile manufacturing process. Additionally, talc functions as a flux agent, reducing sintering temperatures and promoting densification 6,21,48,49 . As a result, careful monitoring of the talc concentration should guarantee the porcelain tiles’ performance, cost‐effectiveness, and properties during production.…”

Reducing the environmental impact of porcelain tile production while maintaining cost‐effectiveness is challenging. This work introduced a novel modeling approach for optimizing a standard composition range comprising kaolinite (15–38 wt.%), illite (0–20 wt.%), quartz (20–40 wt.%), and feldspar (20–45 wt.%) to establish a robust composition interval for porcelain stoneware tiles. The proposed study considers several factors, such as composition impact on the manufacturing sequence, production costs, and CO2 emission. A flowsheet simulation database was generated by coupling the Dyssol framework with MATLAB. This study investigated the influence of raw material composition within the process sequence, the total CO2 emissions, and production costs within the contexts of Spain and Brazil, two of the top five global producers. Granules with a higher proportion of talc and illite exhibit reduced moisture content after spray drying, and these combinations have lower green body porosity after compaction. The addition of talc allowed for decreased porosity content after compaction reduced firing temperature, and lowered costs and CO2 emissions despite the higher prices associated with talc. The proposed simulation methodology offers a powerful decision‐making tool for optimizing raw material composition to minimize cost and CO2 emissions in the porcelain tile production. This methodology represents an early stride toward integrating digital twin methodologies within the ceramic tile sector, facilitating improved process regulation, and promoting the adoption of digital technologies.

“…As depicted in Table 5, sand particles were relatively smooth, and the surfaces of GT particles were rough. Some researchers have investigated GT to improve rubber strength, prepare ceramic tiles, and use as a cementitious material [18,35,36]. There has been rare research on GT environment-friendly concrete.…”

“…Countries with mineral resources and mineral processing produce considerable tailings, thus making the discharge of tailings inevitable. The problems caused by tailings have aroused a growing attention from the public towards the continuous increase of the scale of tailings [17,18]. Since the 20th century, some mining enterprises have committed to the development and utilization of tailing resources for resource depletion, environmental protection, and employment solutions.…”

The development of tailings in concrete technology is not only conducive to the realization of the goal of reducing carbon emissions, but also conducive to the inhibition the occurrence of shortages of sand and gravel supplies. In this study, graphite tailings were used to replace sand in the range of 0~100%, and the mechanical mechanism of graphite tailings concrete was examined through compressive and flexural tests. The mechanical experimental results were evaluated and verified based on concrete macroscopic failure appearance, mesoscopic failure appearance, and physical characteristics of graphite tailings. The results revealed that the concrete strength increases first and then decreases with the increase of the graphite tailings content. Compared to GT00 (GT00 is a specimen with a graphite tailings content of 0%, and so on), GT10~GT60 exhibited better mechanical properties, of which 30% was recommended as the optimal replacement rate. The mechanical properties of GT10 and GT20 had an upward trend, and GT30 had low spalling, with aggregate fragmentation found on the fracture surface. GT30 showed the best resistance to bending and deformation. The mechanical properties of GT40~GT60 had a downward trend. When the graphite tailings content was higher than 70%, the interface defects of the aggregate matrix increased, thus making it easier for cracks to propagate along the interface. Furthermore, the mechanism of graphite tailings replacing sand verified the test results from different perspectives, which provides new analysis ideas for other tailings in environment-friendly concrete.

Endowing polyurethane foam with high fire resistance and smoke suppression is a persistent challenge in the combustion industry. This study introduces a graphite‐tailings and calcium‐alginate (GT@CA) gelatum coating that terminates the heat and mass transfer process in a flexible polyurethane foam (PUF) matrix with fire resistance and smoke suppression. The PUF/GT@CA‐3 composite exhibits high flame retardancy with a V‐0 rating in the vertical combustion test. Furthermore, GT@CA forms protective and char layers that terminate the heat and mass transfer during thermal degradation, the thermal stability and fire behavior of the PUF/GT@CA composites are markedly optimized. Meanwhile, the smoke production rate and total smoke production of PUF/GT@CA‐3 composite are dramatically reduced to 1.17 × 10−2 m2/s and 2.73 × 10−1 m2, respectively (81.19% and 83.26% lower than those of pure PUF, respectively). Finally, the flame retardant and smoke suppression mechanism of GT@CA in PUF is deduced. The GT@CA competently promotes the char forming process of the PUF matrix while fabricating an impervious protective layer. The char and protective layers on the PUF surface restrain oxygen diffusion, heat diffusion, and micromolecule volatilization processes. Hence, GT@CA is expected to expand the application range of PUF matrixes in the advanced materials field.
