A Review on the Recycling Waste Materials for Green Concrete

Abstract

This has increased the generation of solid waste, creating environmental and economic problems on an international scale. The construction industry, one of the major environmental degrading and resource-consuming industries, plays a major role. This study examines how waste material is used in green concrete as a sustainable solution to minimize environmental burdens and save natural resources. Utilizing waste material such as silica fume, fly ash, recycled aggregates, and ground-granulated slag from blast furnaces (GGBFS), recycled plastic, and biopolymers, green concrete minimizes carbon emissions as well as reduces the need for virgin materials. In this paper, it is discussed how the application of such waste products in green concrete minimizes the carbon footprint and saves natural resources, whereas on the other hand, it also saves material and construction costs. Life cycle assessment studies and sustainability analysis give a valuable comparison in overall sustainability between green concrete and conventional concrete. Challenges and future directions in this field elucidate the uniformity of waste material quality, regulatory support, and public acceptance. The scope of further research lies in the development of material characterization, long-term durability studies, and technological advancement, which promise to deliver desired performance and applications of green concrete.
