We are facing natural resource depletion and ecological issue in present on earth. Building industry should take account into climate change and resource consumption. Recycling materials is one of way to become sustainable construction. There are substantial material waste in construction having huge potential to be recycled such as concrete, coal fly ash, steel slag, mining waste rocks, waste glass, coal bottom ash and asphalt pavement.
Recycled concrete as a replacement of coarse aggregate in concrete can be an alternative method for recycling concrete. Most of the construction debris, quarry dust, marble dust, granite dust are added as fine aggregate material in concrete. Based on the application in the concrete the waste materials are processed for recycling in concrete industries.
