Polyethylene terephthalate (PET) with different grain size after grinding (fine and coarse) was recycled used as aggregate for non-conventional lightweight cement mortars. The physical mechanical characteristics were compared to conventional sand-based composites. workability in the fresh state evaluated. Accordingly, composites showed decreases fluidity increases PET percentage weight. Higher thermal insulation lower strengths observed increase plastic dosage due a density decrease porosity Finer samples more resistant (~12–24 MPa) than coarse-grain (~3–23 higher specific surface area of aggregate. Conversely, obtained coarse addition (~0.6–0.2 W/mK vs. ~0.7–0.35 W/mK). A ductile behavior discrete cracks failure mixture. Low wettability which, although porous sand specimens, hydrophobic which contributed water repellency. reported physical, mechanical, thermal, microstructural features suggest potential these both inside outside applications non-structural objects.
