A Review Paper on Assessing the Environmental Impact of Recycled Aggregate Production and Use

Abstract

Garbage management has emerged as one of our planet's most serious challenges, owing to its considerable contribution to environmental issues. Waste from construction and destruction (C&D), together with agricultural waste, glass, and plastic garbage, account for the majority of this waste. Due to its considerable role in environmental problems, garbage management is an urgent global task. Recycling has gained popularity as a way to reduce landfill trash, including the aggregate made from recycled concrete (RCA) from construction and destruction debris (C&D), which has positive environmental impact, the society and the economy. India continues to employ a little amount of RCA in new construction despite its rising cement demand and generation of C&D waste. The use of recycled concrete aggregate (RCA) in construction impacts concrete characteristics with advantages and disadvantages. Challenges include workability, density, and water absorption, mitigated by super plasticizer and altered absorption methods. This paper emphasises the advantages of RCA in structural concrete and the need for enhanced knowledge and ability for sustainable methods for trash management in the context of India's cement consumption and C&D waste management. The paper urges more investigation and effort to advance RCA as a practical option for handling C&D waste and minimising environmental effects.
