Concrete Pavement Recycling Series: Concrete Pavement
Concrete recycling is the breaking, removal, crushing, and processing of hardened concrete to produce recycled concrete aggregate (RCA), a granular material that is generally suitable for use as a substitute for virgin aggregate in various (generally construction-related) applications (ACPA 2009). Concrete recycling has been used
End of life recycling
End of life recycling. The construction industry in the UK accounts for the use of 295 million tonnes of virgin material per year, displaces 22 million tonnes of industrial 'by-product' by industrial ecology each year and produces approximately 150 million tonnes of construction and demolition waste annually.
Strength and Durability Evaluation of Recycled Aggregate Concrete
May 14, 2015 · This paper discusses the suitability of producing concrete with 100 % recycled aggregate to meet durability and strength requirements for different applications. Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete. In general, the quality of ...
