| Abstract Scope |
This study evaluates the potential use of spodumene waste from port activities as a partial replacement for natural aggregates in mortars, contributing to sustainable material development. Mortars were produced with Portland cement, hydrated lime, natural sand, and different spodumene contents. Prismatic specimens (40×40×160 mm) were tested to determine consistency, water retention, air content, compressive strength, water absorption, and bulk density, following normative procedures. The results showed that incorporating spodumene improved some fresh and hardened state properties, notably an increase of approximately 12% in compressive strength compared to the reference mixture. The modified mortars maintained satisfactory performance within standard requirements for all evaluated parameters. The findings indicate that spodumene waste can be technically viable as a partial substitute for natural aggregates, promoting waste valorization, reducing environmental impact, and encouraging more sustainable construction practices. |
