Physico-chemical and Mineralogical Characterization of Soils for the Production of Extruded, Pressed, and Fired Red Ceramic Blocks
摘要
This studyRed ceramic blocks characterizedCharacterization three soils from the red ceramicCeramics industrial hub of Campos dos Goytacazes, evaluating their suitability for the production of extruded, pressed, and fired ceramic blocksCeramic block. Grain size distribution, consistency limits, density, compaction, X-Ray Fluorescence Spectroscopy (EDX), and X-Ray Diffraction (XRDX-ray Diffraction (XRD)) analyses were performed. The Winkler diagramWinkler diagram was used to verify the suitability of the soils for hollow blocks. The chemical composition indicated high amounts of silica (SiO₂) and alumina (Al₂O₃) in Soils 1 and 2, suggesting the presence of kaoliniteKaolinite and gibbsite, while Soil 3 showed a predominance of silica, indicating quartzQuartz. The mineralogy of the soils revealed primarily quartzQuartz and kaoliniteKaolinite. The Winkler diagramWinkler diagram indicated that Soil 3 is more suitable for the production of hollow ceramic blocksCeramic block.
