Description

For many years, the earth’s natural resources have been consumed at a very high rate. Potential resource depletion, CO2 emissions, and high energy consumption rates in production increase the necessity of recycling. All sectors of society are responsible for these concerns, especially the construction industry.

As a primary construction material, concrete is increasingly judged by its environmental impacts, and reusing readily available concrete is becoming very important. Considering that much of the US infrastructures and urban buildings now require renovation and replacement, the concrete left behind can be a valuable aggregate source for new concrete. Such concrete is usually called Recycled Aggregate Concrete. Cost analyses show that recycling concrete as aggregate for new concrete production can be a cost-effective method for construction.
