Engineered Cementitious Composites (ECC) with limestone calcined clay cement (LC3) (2020, background): “Previous lifecycle analysis (LCA) of ECC overlays suggested a minimum 50% reduction in life-cycle emissions and cost, essentially due to an assumed 2% tensile strain capacity [18].”
Mechanical and self-healing behavior of low carbon engineered cementitious composites reinforced with PP-fibers (2020, methodology): “The LCA models based on OPC-ECC demonstrated significant advantages in environmental performance and materials cost over the lifecycle [7,64].”
Development of engineered cementitious composites with limestone powder and blast furnace slag (2010, background): “Therefore, the use of ECC lowers the life cycle cost of structures, although ECC costs two to three times higher than conventional concrete [7].”
Reinforced geopolymer composites for enhanced material greenness and durability (2011, background): “5 billion car-hours every year that American motorists spend stuck in traffic due to the repair of existing infrastructure, roughly 42 Mt of CO2 are emitted3 at a cost to drivers of roughly $62 billion (Keoleian et al., 2005; Keoleian & Spitzley, 2006; Zhang, Keoleian, & Lepech, 2008).”
