“…The diffraction patterns of the raw materials (Figure 3) confirmed the chemical analysis, with the presence of quartz in all samples. Quartz hinders sintering and can impair the mechanical strength of ceramics [45,46]. The melting temperature of quartz is very high (1710 °C), and under normal conditions of calcination of ceramic materials in the construction industry, this temperature hardly exceeds 1200 °C.…”

“…The anorthite found in C1 was also resistant to temperature changes. Minerals such as kaolinite and muscovite, found in C2 and S, decomposed with increasing temperature and reduced density, resulting in porosity in ceramic bodies [42,45,47]. The combination of quartz and kaolinite was responsible for the low interaction between the grains in the mixtures because both have little affinity for water [27].…”

This study evaluated the grain size and high organic content from drinking water treatment sludge (DWTS) in the properties of ceramics. Samples were studied using raw and oven dried DWTS at 110 °C in two granulometries (0.180 mm and 0.075 mm), with and without calcination (550 °C), as partial replacement of two soils commonly used in ceramic production. Specimens were prepared with 5, 10, and 20% DWTS and calcined at 950 °C to determine their chemical, physical, mineralogical and mechanical properties. The DWTS reduced the density and increased the absorption and shrinkage of the specimens after calcination. An increase in strength with up to 10% sludge, driven by the presence of fluxing agents, was verified. The processing method had little influence on the properties of ceramic with above 10% of sludge. In conclusion, the use of raw DWTS obtained better results with low energy usage for its reuse.

“…Another large-scale agricultural and industrial waste is from wood processing (chips, sawdust and dust). The interest in the use of sawdust is due to the high volume generated as well as the physical and mechanical properties of the wood, being several studies on composites from these residues (Csicsely et al, 2009;Vilane, 2010;Malaiskiene, MacIulaitis, & Kicaite, 2011;Marques et a., 2014;Corrêa et al, 2015;Badea & Dan, 2016;Christoforou Research, Society and Development, v. 9, n. 11, e59891110308, 2020(CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i11.10308 et al, 2016Muñoz et al, 2016;Jokhio, Syed Mohsin, & Gul, 2018;Khurshid et al, 2018).…”

The building construction is responsible for the largest industrial sectors in the world, with high energy demand and use of natural resources. Given the scarcity of natural resources and the energy crisis, the use of waste in building materials becomes a target. Therefore, this study aimed to evaluate different treatments with pine sawdust and coffee husk additions, both at 10% by mass and also evaluated in drying and burning. The treatments were evaluated by bulk density, linear shrinkage and compressive strength. In the treatments without burning, it was possible to verify that the addition of 10% of residue reduces the mechanical resistance of the material considerably but improves the physical properties. In the burned materials, it was observed that the addition of residues is unsatisfactory due to the high temperature, carbonizing them, increasing the porosity, thus destabilizing the material, negatively affecting the physical and mechanical properties.

“…In general, the crushing performance for CGPs depends on the statistical characteristics of geometric shape and mesostructures, such as internal composition distribution, phase continuity, and initial damage. Currently, research studies on the characterization of morphological and mechanical properties of individual CGPs are mainly based on experimental analysis [1][2][3][4]. Although the experimental method could provide statistic results, unavoidable sampling errors are widely existed by using experimental analysis.…”

The paper presents an application of milli- and micro-XCT to mesostructure characterization of CGPs and failure patterns analysis using dynamic impact simulations. In this study, XCT scanning experiments are firstly conducted on CGPs, followed by a series of image analyses with qualitative results. Then, the 3D mesomorphological parameters and internal composition of individual particles are quantitatively characterized. Finally, dynamic impact loading in y-axis direction is modelled to investigate the 3D mesostructure and different impact velocity effects on failure patterns of individual particles. The studies show that the mesomorphological parameters present different distribution characteristics in individual CGPs. The approximate location of gangue phase is the key parameter that should be taken into account to study failure patterns as well as fracture mechanism of the heterogeneous rock materials. The XCT image-based numerical model proved to be an effective tool that gives insights into the mesodeformation mechanisms of heterogeneous coal rock (HCR) undergoing dynamic impact failure behavior.
