I ran across and interesting article this morning on how recycled aggregates could make concrete more sustainable. The article discusses the effects of concrete on our environment and how using recycled aggregates from concrete-based structures which have been demolished as they are upgraded or replaced.
The article entitled: Is Recycling the Answer To Concrete Sustainability, goes onto explain the process of how demolished material can be crushed at the demolition site and be converted into 600 tons of material per hour that could be reused, thus, reducing the need for new sand and gravel to be mined, saving on energy, and the cost of transporting fresh aggregate to building sites.
I hope you will take the time to read this article which provides a way to produce environmental friendly concrete.
