Abstract
The industrial sectors around the world have resorted to the use of recycled materials to reduce environmental impacts and enhance sustainability. The utilisation of recycled concrete aggregate for concrete production will greatly decrease the demand for natural aggregate as well as lower the amount of construction and demolition waste that will be sent to the landfill. The severity of the issue of global warming has increased the interest from the construction industry to determine and control the amount of greenhouse gases associated and generated by concrete production and construction activities. The impacts of recycled concrete aggregate on the mechanical properties of concrete have been investigated over the years with specific recommendations and replacement percentage reported to improve performance. This paper reviews the CO2 emission of recycled aggregate concrete based on investigations conducted by researchers. Recycled aggregate concrete was concluded to lower the amount of CO2 emission and resulted in more reduction when other waste materials like silica fume, fly ash, and GBBS was added as admixtures.
