Waste Concrete Recycling

Concrete recycling - Wikipedia

The demand of construction aggregate was projected to reach 48.3 billion metric tons by 2015; the highest consumption was to be in Asia and the Pacific. Demolition to make space for new structures generates a large volume of waste. The most common way to dispose this waste is to dump it in a landfill, which can pollute the air and water. This, along with the resource use of this construction, has caused more and more countries to consider the importance of recycling of demolition waste.
