TCA is inviting project submissions to be considered for a new Top 10 list highlighting the \u201cMost Recycled Concrete Content\u201d on a project.<\/p>\n

The list, which already has one entry, was initiated in response to the market\u2019s interest in sustainable solutions. \u201cThe use of Tilt-Up concrete goes a long way in achieving sustainability, thanks in large part to its durability,\u201d said Jim Baty, TCA\u2019s Technical Director. \u201cStructures built with concrete tend to last two to three times longer than buildings constructed with other common building materials. In addition, the same qualities that make concrete a viable green material, such as thermal mass and reflectivity, also help make concrete structures sustainable by providing constant energy efficiency throughout the building\u2019s life cycle. Also, recycled aggregates and supplementary cementitious materials are of great interest in the market now, and we see them being used in increasing quantities.\u201d<\/p>\n

According to Baty, buildings seeking Leadership in Energy and Environmental Design (LEED) certification can benefit greatly from the material and resources\u00a0opportunities afforded by Tilt-Up construction, particularly when it\u2019s used in conjunction with recycled-content concrete. Materials such as reinforcing steel bars and concrete mixtures containing fly ash, ground granulated blast-furnace slag (GGBF) or possibly silica fume, aid in certification, as does the use of materials that are produced within a 500-mile radius from the building.<\/p>\n

\n

Such was the case for the Enterprise Park project, which currently tops the list as the greatest use of recycled aggregates for a Tilt-Up structure, with 2,305 tons of recycled content used in the wall and foundation ready mixes. The 441,000-square- foot office-park project is part of the redevelopment of Denver\u2019s former Stapleton International Airport, and the recycled aggregates used were drawn from 6.5 million tons of material that once comprised the airport\u2019s runways. Not only did the proximity of the recycled material give the project an extra environmental boost toward LEED certification, but it also helped keep costs low. In addition, the use of recycled material allowed the concrete admixtures to be tailored to the needs of each part of the project.<\/p>\n

\u201cUsing recycled aggregates gives ready-mix suppliers greater flexibility in customizing mix designs that fulfill the needs of the project,\u201d says Jay Hock, vice president of sales and marketing for ReCrete Materials, Inc., which mixed the concrete for the project. \u201cDepending upon the recycled aggregate, you may be able to reduce your cement content and\/or change the ratio of cement to fly-ash\u00a0or slag.\u201d The foundation mix for the Enterprise Park project incorporated 620 tons of recycled aggregate and 115 tons of fly-ash, while the Tilt-Up walls featured 1,570 tons of recycled aggregate.<\/p>\n

\u201cWe noticed little, if any, difference\u00a0in the recycled material, including the ability to pump and finish,\u201d said Marty Christensen of CAL Construction Company, the Tilt-Up and foundation subcontractor on the project and a longtime TCA member. \u201cIn fact, strengths have actually come out higher. I would not hesitate to use recycled materials again if they were available.\u201d<\/p>\n

This project marked CAL Construction\u2019s first experience using a recycled-content mix, and Christensen credits ReCrete, which specializes\u00a0in creating recycled-concrete ready\u00a0mixes, with helping the project run smoothly. \u201cSome traits of the concrete were different due to different aggregates, cement and admixtures, so it was a real asset to have a supplier with experience and a knowledge of mix designs that consist of recycled aggregates.\u201d<\/p>\n<\/div>\n

The completed Stapleton Enterprise Park will house three industrial-office buildings with office, showroom, research, assembly and warehouse space, featuring 10-foot-tall glass windows and a host of energy-efficient features. The office park is conveniently located with access to the city\u2019s major transportation sites and corridors, including Interstates 70 and 25, and the Denver International Airport. According to David Johnson of The Etkin Johnson Group, the\u00a0real estate developer for the project, \u201cStapleton Enterprise Park will meet\u00a0the city\u2019s growing demand for Class A warehouse\/distribution and industrial flex space, while also providing businesses with a highly desirable address.\u201d<\/p>\n

Those interested in their project being considered for the TCA\u2019s\u00a0Top 10 list highlighting the \u201cMost Recycled Concrete Content\u201d on a project should contact Baty at jbaty@tilt-up.org or call the Association at 319-895-6911.<\/p>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
