Abstract

Low-carbon concrete offers a critical solution to cut CO₂ emissions from traditional concrete. This review highlights its composition, benefits, and performance, with a focus on supplementary cementitious materials such as fly ash and slag, which partially replace Portland cement to reduce embodied carbon. Alternative binders, such as geopolymers and magnesium-based cements, further reduce emissions and improve durability. Carbon capture and utilization technologies also help reduce emissions by binding CO₂ during curing. Studies show that low-carbon concrete can achieve mechanical properties comparable to those of conventional concrete, with potential carbon reductions of up to 22%. Optimized mix design, continued research, and strong policy support are essential for its widespread adoption.
