Effect of Modifying Additives on Mechanical Properties of ...
and mechanical properties of refractory concrete after exposure to high temperatures. A complex binder together with firestone aggregates was used for production of refractory concrete, which was reinforced simultaneously with micro fibre (1 wt % and 3 wt %) and micro silica ( wt %, wt % and 5 wt %). Unmodified concrete was produced as well.
