Low-carbon Application of Renewable Concrete in Green Buildings

Abstract

In recent years, the rapid development of the construction industry has driven a continuous rise in the consumption of building materials. Meanwhile, the concept of green development has increasingly taken root in people's minds, and the recycling and reuse of building materials have gradually become a focus of attention in industry. This initiative can not only reduce resource waste and alleviate environmental carrying pressure but also effectively control construction costs, thus having both ecological and economic value. As the most widely used basic material in construction projects, the recycling of concrete is of crucial significance to the development of green buildings. This paper first elaborates on the core definition of green buildings, clarifies their core connotations of energy conservation, environmental protection, and sustainable development, and introduces the evaluation criteria for green buildings in terms of resource utilization and environmental impact. It then focuses on analyzing two mainstream types of recycled concrete: one is recycled concrete based on aggregate recycling, and the other is recycled concrete prepared from industrial waste and by-products. At the same time, it objectively examines the advantages and disadvantages of these two types of recycled concrete in terms of performance, cost, and environmental friendliness. Finally, the study concludes that there are still deficiencies in the current technical systems, evaluation criteria, and application research related to recycled concrete, which need to be further improved and optimized, so as to provide directional references for the development of green building materials in the future.
