Abrasion resistance and strength properties of non-fibrous and steel fiber reinforced mortars with different aggregates

Abstract

In this paper, an experimental investigation was carried out to study the effect of using different aggregateson the abrasion resistance, flexural and compressive strengths of the manufactured OPC mortars. Wastefoundry sand and calcareous limestone were used as a partial replacement with the standard sand. Theaforementioned procedure was conducted with and without the reinforcement of steel fibers in order toinspect the significance of fibers on the intended tests. Results revealed the fact that using fiberreinforcement and waste foundry sand together proved to be in benefit of improving the characteristics ofthe 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 thecontrol specimen.
