A review on concrete recycling

Abstract

Concrete is one the most used material in construction. Considering its capacity to harden upon water contact, solidification, and acquisition of full strength, concrete becomes capable of withstanding significant stress. Over the past century, concrete structures have gained immense popularity and found extensive application in diverse architectural project. This prominence places concrete at the forefront of contemporary design and high-performance structure construction, due to its inherent structural benefits. Consequently, concrete production has witnessed a surge, facilitated by on-site production methods and straightforward construction processes. However, this heightened production has led to a significant generation of concrete waste, reaching up to 80 percent of the original produced volume in some regions worldwide. Recognizing the environmental implications, the reduction of concrete waste through recycling has emerged as a sustainable approach. Extensive research has been conducted to explore methods such as concrete recycling and the incorporation of other waste construction materials into concrete, thereby investigating their effects on concrete properties. This comprehensive review delves into the various material mixtures employed and their implications on the application of recycled concrete.
