Abstract

The construction industry contributes to a large amount of carbon dioxide (CO₂) emissions, mostly because of the widespread use of ordinary Portland cement (OPC). Rapid urbanization and infrastructure development in Bangladesh have led to the growing demand for sustainable construction materials. The review describes the possibility of using low-carbon concrete (LCC) as an alternative to conventional concrete in order to reduce the impact of conventional concrete on the environment. The study covers the concept of LCC as per ACI 323-24 and investigates the feasibility of using locally available materials such as Fly ash, Ground granulated blast furnace slag (GGBFS), Rice husk ash (RHA), and recycled concrete aggregates (RCA). The effect of these materials on workability, mechanical, and durability properties is examined. The advantages of LCC are emphasized, including reduced greenhouse gas emissions, conservation of natural resources, and the use of industrial and agricultural by-products. The technical, regulatory, supply chain, and market acceptance challenges to the widespread adoption of LCC are also addressed. The review suggests practical strategies and local resources available in Bangladesh that can help in the large-scale adoption of LCC. The results show that LCC can be a significant contributor to the reduction of environmental impacts of the construction industry while providing acceptable engineering performance and fostering sustainable infrastructure development.
