Ecoefficient materials in the context of cement and concrete refer to components designed to reduce environmental impacts while enhancing performance and economic viability. These materials, including alternative cementitious materials (ACMs), recycled aggregates, and natural fiber reinforcements, aim to minimize the consumption of virgin resources, lower carbon emissions, and improve the lifecycle sustainability of concrete structures. Ecoefficient materials are particularly vital in today’s construction industry as it moves toward greener practices to mitigate climate change and reduce the depletion of natural resources.
