Bottom Ash from Mineral Coal as Aggregatein Mixtures for Ceramic Products

Abstract:

The objective of this work is to analyze ashes from a thermal power plant with the aim of determining its environmental aptitude for reutilization as aggregates in clay mixtures for ceramics production. To achieve this objective the waste material was characterized by different techniques: optical microscopy, scanning electronic microscopy, conductivity, pH, among others. Clay samples with bottom ash addition, up to 50%, were prepared. These samples were thermally treated at 950oC and then characterized with diverse techniques in order to determine their behaviour in service. The obtained results show the high feasibility of reutilization of the studied waste as raw material in the production of ceramic products.
