Sustainable concrete uses less energy and produces fewer carbon emissions than regular concrete. It incorporates waste and recycled materials like fly ash and slag to replace portions of cement. Using these supplementary cementitious materials can increase sustainability by reducing embodied energy and carbon in the concrete.
