RECYCLED CONCRETE. Concrete recycling is becoming a popular way to utilize aggregate left behind when structures or roadways are demolished. In the past, this rubble was disposed of in landfills, but with more attention being paid to environmental concerns, concrete recycling allows reuse of the rubble while also keeping construction costs down.

Concrete produced from recycled aggregates is likely to be used for structures of average span and in conditions of low aggressively. However, the study of recycled concrete micro-structure and their durability can complete and improve this study. Such a study can extend the usage range of recycled aggregates-based concrete in civil engineering.

the adoption of sustainable construction practices. Economics is a component of sustainability, and concrete recycling offers the potential for major savings in the costs of aggregate, which comprises 20%–30% of the cost of pavement con-struction materials and supplies (Halm 1980) and 10%–15% percent of total con-struction costs (excluding engineering and right-of-way …
