RT Journal Article T1 Ceramics for Building Structures Made from Contaminated Soils: A Fuzzy Logic Intelligence Approach to Circular Mining A1 Terrones Saeta, Juan María A1 Camazón Portela, Daniel A1 Luís, Ana Teresa A1 Suárez Macías, Jorge A1 Grande Gil, José Antonio AB Soils contaminated by mining activities are a major environmental concern, and to avoidthis type of environmental impact, carrying out high-cost processes is necessary. For this reason, asolution is proposed in this study in order to eliminate the soils contaminated by mining activitiesand, in turn, prevent the soil’s contaminating elements from causing harm. All this is achievedby using contaminated soils as raw materials for the production of ceramics for bricks. For thispurpose, the materials were initially characterized physically and chemically, and different ceramictest pieces were manufactured with different percentages of clay and contaminated soil, subsequentlydetermining the physical properties and the leaching of toxic elements. In this way, it was possible toevaluate, via innovative data mining and fuzzy logic techniques, the influence of the contaminatedsoil's contribution on the properties of ceramics. Based on this, it was possible to affirm that thecontaminated soil incorporation negatively affects the physical properties of ceramics as well asthe leaching of polluting elements. The ceramic formed by contaminated soil and clay has a lowercompressive strength, and it is associated with lower linear shrinkage and lower density, as wellas higher porosity and cold-water absorption. However, the addition of different percentages ofcontaminated soil (up to 70%) to clay created a ceramic that complied with regulation restrictions.Therefore, it was possible to obtain a sustainable material that eliminates environmental problems ata lower cost and that fits within the new circular mining concept thanks to fuzzy logic techniques.
