AB [EN] Mining activities are essential for a population’s development; however, they also producenegative effects such as the production of waste, an impact on flora and water pollution. On theother hand, construction is one of the sectors which is most demanding of raw materials, with oneof the main such materials being water. For this reason, this research evaluates the feasibility ofincorporating water contaminated by mining waste into ceramic materials for bricks. In this way,the use of water is reduced and, on the other hand, the contaminating elements of the mining waterare encapsulated in the ceramic matrix. To achieve this, the clay used and the contaminated waterwere first analysed, then different families of samples were conformed with different percentages ofcontaminated water. These samples were tested to determine their physical and mechanical properties.At the same time, leachate tests were carried out to determine that the ceramic material created did notcause environmental problems. The test results showed that the physical and mechanical propertiesof the ceramics were not influenced by the addition of contaminated water. On the other hand, theleachate tests showed that encapsulation of most of the potentially toxic elements occurred. However,the use of contaminated water as mixing water for ceramics could only be performed up to 60%,as higher percentages would leach impermissible arsenic concentrations. Accordingly, a new wayof reusing water contaminated by mining activities is developed in this study, taking advantage ofresources, avoiding environmental pollution and creating economic and environmentally friendlyend products.
