Implication

Randomized trial assesses compressive strength and carbon footprint in eco-concretes, suggesting significant environmental benefits.

Key Points

This study aims to evaluate the mechanical, environmental, and economic performance of eco-concretes using high levels of mineral additions.
Thirteen concrete mixes were developed, substituting Portland cement with 30%, 40%, 50%, and 60% blast furnace slag, fly ash, and limestone filler.
A multi-criteria approach was employed to analyze carbon footprint, energy consumption, and material costs.
Innovative performance indicators were created to assess the effectiveness related to 28-day compressive strength.
Blast furnace slag was the most effective additive, reducing carbon footprint by 41.5%, energy consumption by 37%, and material costs by 27.3%.
Compressive strengths of eco-concretes with blast furnace slag were comparable to reference concrete.
Fly ash and limestone filler, while beneficial, showed less favorable performance indices compared to blast furnace slag.
