Synthesis and characterization of calcium sulfoaluminate clinker (Klein complex) from secondary raw materials of anthropogenic origin – preliminary studies

The collection contains the results of research related to the implementation of the Miniatura5 project entitled "Synthesis and characterization of calcium sulphate alumina clinker (Klein complex) from secondary raw materials of anthropogenic origin - preliminary studies"The idea of ​​the project was to determine the possibility of synthesizing the main component of calcium sulphate alumina cement, i.e. ye'elimite, from by-products and / or waste materials, i.e. aluminum anodizing by-product (AL material) and asbestos-cement waste (AC material). The scientific activity planned for implementation was divided into stages in which: (a) the characterization of waste and raw materials was performed, (b) tests of ye'elimite synthesis from available materials were carried out - at different firing temperatures for various variants of raw material sets, along with the characteristics of the obtained product, (c) studies of the binding properties of selected synthesis products were carried out. As part of the research, the following research methods were primarily used: XRF, XRD, SEM, DTA-TG. The effect of the proposed scientific activity is a preliminary determination of the quality of the obtained ye'elimit and the possibility of producing CSA cement clinker from secondary raw materials.
