Abstract

The construction industry has a significant impact on the environment, mainly due to high emissions of carbon dioxide (CO2), resources consumption, and waste generation. Cement production, as a fundamental component of concrete, accounts for substantial CO₂ emissions. This study aims to compare the concretes’ environmental performance when produced replacing Portland cement with Eucalyptus Chip Ash (ECA), assessing compressive strength (at 28 and 56 days), binder intensity index (BI), and the CO2 intensity index (CI). Three different ash particle sizes were tested (ECA0.30, ECA0.15, ECA0.075), characterized in terms of: particle size, BET surface area, chemical composition (XRF), phase composition (XRD), microstructure (SEM), and cement Performance Index (PI) at 28 days. The results indicated that the ECAs showed low pozzolanic activity (PI
