Implication

Randomized trial evaluates mechanical performance and environmental impacts of green concrete mixtures, suggesting optimal formulations for sustainability.

Key Points

This study aims to analyze the mechanical performance and environmental impacts of green concrete mixtures using supplementary materials.
Experimental program assessing 22 concrete mixtures incorporating bentonite, fly ash, and silica fume.
Evaluation of workability, compressive strength, and durability against seawater sulfate attack.
Life cycle assessment conducted using One Click LCA software.
Cement contributes 83–95% of the global warming potential (GWP) across mixtures.
Mixtures with 50% fly ash achieved a GWP reduction of up to 50.1%.
Mix 20 (4% bentonite + 15% silica fume) showed the highest compressive strength at 49.0 MPa at 28 days.
