Resumen
[EN] Larger consumption of natural fine aggregates (NFA) leads to an increase in cost, energy, and
negative environmental impact. On the contrary, the larger production of construction waste
results in the generation of recycled fine aggregate (RFA), which requires safe disposal. The aim
of study, is to the hunt for such alternatives, compares the mortar mechanical and durability
properties with and without RFA. High strength mortar specimens were produced with mix
proportion as 1:3 using RFA as partial replacement for NFA as 0%, 25%, 50% and 100%. The
mechanical and durability performance of all specimens was assessed in the terms of compressive
strength, flexural strength, water absorption and mercury intrusion porosimetry. Mechanical
performance is confirmed by microscopic studies. The main results display that the mortar with
25% of RFA, performed better, which are related to pore structures and their distribution. It is
noted that the, pores also increase with the increase in RFA content. The effect of pores on the
strength and their relationships are assessed.
