Sažetak
Previous research has shown that the reuse of bauxite residues from alumina production, also known as red mud, has potential for use as a cement substitute, especially when combined with other supplementary cementitious materials. The idea of this research was to investigate the synergy between locally available red mud, clay and limestone. The synergy study included measurements of heat of hydration at paste level and compressive strength on mortar samples. The mineralogical composition of the mixed binder was analysed by thermogravimetric analysis which is indirect method for confirmation of mineral phases. The investigations showed that there is a positive synergy between red mud, clay and limestone, and with good optimization, a higher cement replacement can be achieved without affecting the mechanical properties of the mortar.
