CONCRETE using materials recycled from the nearby decommissioned airport means reduced costs for fuel and truck miles, and fewer emissions from transport. The success that the two companies have experienced at Stapleton did not go unnoticed. In April 2005, the City of Irvine, Calif., selected Recycled Materials Company to perform recycling and material removal operations at the former El Toro Marine Corps Air Station, handling a total of approximately 3.5 million tons of concrete and asphalt. While the project was recently put on hold, plans are still in place to turn El Toro into the Orange County Great Park — one of the largest metropolitan parks in the U.S., according to the Great Park Conservancy. Mark Wachal, co-founder and partner in Recycled Materials Company, says the Great Park opportunity is a huge step forward in the recycled concrete movement. “Our program encompasses all things we have learned at Stapleton,” Wachal says, maximizing every resource available at the site and creating almost 10 different recycled products. The resulting recycled concrete aggregate products include an aggregate base course (for use under pavement); a bedding product for underground utilities; landscaping material called ToroStone (essentially three by fourfoot pieces of runway) that can be used for water revetment, stream protection, park benches and water features; and — of course — fine and coarse aggregate components for ready mixed concrete.

Both structures are built with insulating concrete forms (ICFs). “We think concrete is a great building material because it’s very durable, termites won’t eat it, it’s easier to manage moisture issues with it—and the ICF system makes it a great energy performer,” says Southface executive director Dennis Creech. For the Eco Office, Southface used ICFs from PolySteel, creating a buildand ing that has a life beyond being a “show home,” according to Will Oliver, president of Oliver Building Solutions and supplier of the ICFs. The energy efficiency of the ICF system allowed Southface to reduce their HVAC tonnage by eight tons on the 10,000-square-foot structure. The savings will be tracked and documented, says Creech: “With support from PolySteel, we’ve fully instrumented this building. We’ll be monitoring (a recovered resource) as a replacement for cement the moisture, mechanical and plumbing, and we’ve got thermocouples on in concrete. the outside and inside of walls to measure flow of temperature.” Data will be posted online for observers. When you specify fly ash as replacement for cement in Concrete for the structure incorporated supplementary cementitious concrete, you help reduce CO2 emissions from cement materials: in the ICFs, cement replacements were at 15 percent fly ash and production, conserve landfill space, and decrease 20 percent slag cement; in footings and slab on grade, that replacement water usage. You also enhance workability and level was pushed to substitute 20 percent with each material. “Being a chemical attack resistance, increase strength and produce more durable concrete. green building demonstration project, we wanted to use as high a replacement amount as possible,” says Frank Burdette, Southface’s project manContact Headwaters Resources for free technical literature ager with commercial green building services. and information on how fly ash use benefits the environment And concrete is sprinkled throughout the organization’s campus: perviand produces better concrete. ous concrete is used for sidewalks, plazas and driveways; concrete countertops adorn kitchens and public restroom facilities; exposed, colored concrete flooring in the main entryway serves to connect the office buildwww.flyash.com I 1-888-236-6236 ing with the 6,500-square-foot residential structure; and recycled concrete aggregate was used in landscaping. + HOWTO combat global warming, 10:20:25 AM reduce the production of greenhouse gases, stronger infrastructure.
