Abstract text:
The addition of calcium sulphate (CS) as replacement of cement in the traditional mixture develops a so-called ecological mineral matrix with favourable influence on the setting time of the material, speeding up the hardening, improved workability, compactness, homogeneity of material with convenient mechanical properties. In this paper the authors analyse the properties of this binder obtained by partial replacement the Portland cement in the production of concrete with a product obtained from recycled wastes. The analysis of the micro structure and the evaluation of most important technological and mechanical properties confirm the suitability of the obtained matrix for applications in construction.
