Apparently, the strength of the concrete is also holding up (pun intended). Tests have been conducted to compare 100% virgin aggregate and varied percentages of recycled materials. The results are that some recycled materials are equal to or, in some mixes, even superior to 100% virgin aggregate. According to recycling specialists, recycling of concrete is a relatively simple process. It consists of breaking, removing, and crushing existing concrete into a material with a specified size and quality. It is overall agreed upon that when natural sand is used, as much as 30% of natural crushed coarse aggregate can be replaced with coarse recycled aggregate without significantly impacting any of the mechanical properties of the concrete. However, replacing higher amounts will result in increased drying shrinkage, while strength...
Recycled Materials Co. (RMC) of Arvada, Colo., were given many reasons why this could not be done when they first suggested it. However, the CEO Ken Buesing, president Mark Wachal, general manager Rick Givan and the company's other leaders did not back away from the project. Instead, they kept on pursing it and have actually found many of the developers who have carted away the used cement. The results of their efforts and the activity overall were quite impressive. On completion, 975 acres of concrete and asphalt will be recycled, yielding enough material to construct a two-lane roadway roughly 10,000 miles in length. More importantly, others are now following their lead and more concrete…
The standards include recycling C & D. debris. The Chicago Center for Green Technology got an award for its building (Grzeskowiak, 2006). Our city could do the same. Tallahassee, Florida recently renovated their Solid Waste Administration building to conform to green standards (Grzeskowiak, 2006). A successful "green" building has been built in New York City -- the first green high-rise residential building in the United States. The designers set

A second major facto in the growing trend for a new greener industry is that these measures also represent a more efficient operation from a financial perspective as well. For instance, recycling aluminum cans on the job is an example of a sustainable practice that contributes in a positive way to the bottom line (Shepherd, 2009). Recycling aluminum cans on the jobsite help to feed the local economy as well.
