The use of SCMs played an important role for the canister storage facility at the Hanford Site nuclear facility. The CSB is a large, 42,000 square foot facility in Hanford’s 200 East Area which stores about 2300 tons of spent nuclear fuel packaged in approximately 400 Multi-Canister Overpacks (MCO’s). The MCO’s are stored in 220 carbon steel tubes within a below grade concrete vault. The MCO’s will be safely stored in the tubes until permanent placement in a National Repository.  

The San Francisco Public Utilities Commission (SFPUC) Building (illustrated in Fig. 1) provides an excellent case study for the integration of (Building Information Management) BIM to achieve a sustainable building. This building required carbon accounting for construction materials and construction activities, and is LEED Platinum certified. Figures 2 through 4 show various views of the core walls of the building that incorporate vertical post-tensioning.

Although the floors are made with specialty components such as iron aggregates, impact from garbage trucks unloading and abrasion from heavy equipment moving trash can shorten the average transfer floor life to only 1 to 3 years. For the Solid Waste Authority, the downtime of any plant and the logistics of diverting continually accumulating trash are paramount. Floor rehabilitation typically averages 2 months of construction time before the floor goes back into operation.

The Midfield Terminal at the new Indianapolis International Airport opened in 2008, and includes a massive 7000-car parking garage. Each of the five parking levels is approximately 500,000 ft² (46,500 m²). The two-way post-tensioned concrete design for the garage maximized the benefit from the chosen HPC mixture.

This 5200 ft² (483 m²) parking deck (Fig. 1) was nearing the end of its service life, and was characterized by widespread concrete deterioration and severe corrosion of reinforcing and prestressing steel. As an alternative to demolition and reconstruction, the owner was able to repair the structure, reducing environmental impact while providing significant initial cost savings, life-cycle cost savings, and schedule savings.

A premier example of aggregate recycling on a large scale is at the site of the former Stapleton Airport in Denver, CO. The project included demolition, removal, and recycling of 1400 acres (5.7 km²) of concrete runways and other paved surfaces, for a total of 6.5 million tons (6 million metric tons) of aggregate (Construction Materials Recycling Association 2010). Figure 1 shows the on-site concrete recycling operations. The aggregate was used throughout the redevelopment of Stapleton for road base, erosion control, and also in new concrete.
