Abstract
In this paper, an experimental investigation was carried out to study the effect of using different aggregates
on the abrasion resistance, flexural and compressive strengths of the manufactured OPC mortars. Waste
foundry sand and calcareous limestone were used as a partial replacement with the standard sand. The
aforementioned procedure was conducted with and without the reinforcement of steel fibers in order to
inspect the significance of fibers on the intended tests. Results revealed the fact that using fiber
reinforcement and waste foundry sand together proved to be in benefit of improving the characteristics of
the resulted matrix. MIX 3 yielded the best results in terms of strength properties and abrasion resistance.
Moreover, the mixes with limestone aggregates presented a better performance when compared to the
control specimen.
