Deskripsi

Background: Construction and demolition wastes (CDW) are among the bulkiest municipal wastes which are often made of concrete. According to the high volume of these wastes, it is essential to use the recycling strategy to manage C&D wastes. Recycling has three major advantages to make CDW management more efficient, including; reducing the demand for natural resources, reducing the cost of energy production, and increasing the capacity of the landfills. According to this, the aim of current study is to review concrete waste recycling methods. Methods: In the initial search of articles, a total of 74 articles from 2005 to 2022 were found which was reduced to 50 after removing duplicates. Then, in the screening stage, the title and abstract of the articles were reviewed and at the end, 28 articles remained. Then, to obtain related articles, the full text of the screened articles was studied and finally, 22 articles remained which were used in the present study.. Results: Recycled aggregates usually have limited use in the construction industry; but the technologies discussed in this study can increase the quality of recycled aggregates and therefore these aggregates can be used in better and more applications. Conclusion: There are advantageous suggestions for the improvement of construction waste recycling including; the proper destruction of buildings, revision of construction methods, and encouragement to design structures based on native architectural potentials. The main ways to achieve these goals include; government support, raising public awareness, establishing an administrative system for recycled materials, approving relevant laws, and devising construction methods based on local capabilities.
