In recent decades, the interest in refractory materials which are formed without baking - by chemical
bonding - has increased significantly, as their production is less complex and more economical than
the production of classical refractory materials, which involves a long baking process. In this work,
as a chemical binder, phosphoric acid, which is intensively reacted with refractory oxides MgO, SiO2
or Al2O3, was used, and the resulting mass quickly hardened. Quartz sand of the Bukinje deposit,
Tuzla, was used as filler. In the previous researches it has been proved, and this work has confirmed,
that the chemical bond between the filler and the binder without the binding agent will not occur.
Illite-kaolinite clay from deposit Sočkovac -Gračanica, was used as a binding agent. In this paper, the
influence of the amount of phosphoric acid and clay, as an activator of binding, to the physical -
mechanical properties of refractory concrete was investigated.
