Innovations in Sustainable Concrete Design and Construction

This research paper explores recent advancements in sustainable concrete technologies, including the use of geopolymer cement, supplementary cementitious materials (SCMs), recycled aggregates, and fiber-reinforced composites. It highlights real-world applications of 3D concrete printing (e.g., COBOD system), examines case studies from Oman, the Netherlands, and Malaysia, and evaluates the environmental and structural benefits of low-carbon designs. The paper provides valuable insights for engineers aiming to decarbonize the construction sector through durable, climate-resilient, and innovative structural approaches.
