2018 SCA Award Nomination Form
NEW Research Award Category Application
This year, the SCA is incorporating a research award category to the awards program. The goal is to get a better understanding of the work students and professors are doing in the field of slag cement, provide them recognition and the opportunity to meet other slag cement professionals.
The nominations are open to any U.S. or Canadian college or university student or group of students that have done research that includes the use of Ground Granulated Blast Furnace Slag, more commonly known as slag cement. Nominations are open August 1st, 2018 and will close on November 1st, 2018. Details on the qualifications, process, and activities associated with the program can be located in the nomination packet below.
**Winning nominations will receive a $1,000 stipend for expenses to attend the awards ceremony at the 2019 ACI Convention in Quebec, CA.

SCA Project of the Year Awards Background
Since 2010, the Slag Cement Association has been running its annual slag cement project of the year awards program. The slag cement awards recognize projects for excellence and innovation in concrete using slag cement. For the 2017 awards, nine projects were honored in the categories of architectural design, durability, green design, high performance, sustainability, and a new category, innovative applications.
“The SCA's awards program does a great job of showcasing how versatile slag cement can be, and how it can help create stronger, more durable, and sustainable concrete structures. These case studies are a great resource for the industry.”
-Ed Griffith, President, SCA
2017 Awarded Projects:
Barrier One Headquarters – Winter Garden, Florida
This building is using 50 percent slag cement in all concrete applications, including foundation, slab-on-grade, paving, sidewalks, casting beds and tilt-up panels. The concrete over-achieved required strength designations and the slag cement also helped contribute to the superior performance of the tilt-up concrete where early lifting strength was required.
I-91 Brattleboro Bridge – Brattleboro, Vermont
Standing 100 feet above the West River valley, Vermont’s first cast in place segmental concrete bridge carries Interstate 91 over Vermont Rt. 30 and West River. Slag cement was used in mass concrete pours and in ternary mixtures to increase bridge strength, reduce permeability and to improve the workability of the concrete.
Ecole Kenwood French Immersion Elementary School – Columbus, Ohio
More than 20 percent slag cement was used as a portland cement replacement to enhance color and reduce overall concrete costs for this elementary school. Slag cement also helped create a more sustainable building by using recycled, local materials and contributes to the buildings overall durability.
NVIDIA Building – Santa Clara, California
Category: Green Design
With a unique triangular-shaped design, this building was created with a major focus on seismic activity concerns within the Northern California region. Approximately 65 percent of the concrete consists of 20-30 percent slag as a cement replacement. The use of slag cement also helped reduce the building’s environmental impact, resulting in an approximate savings of 6.7 million pounds of carbon emissions.
Panorama Building – Miami, Florida
This 83-story, mixed-use building uses slag cement in more than 13,000 cubic yards of mat foundation concrete - all vertical elements - and 50 percent of the elevated decks. The slag cement used in mass concrete allowed for higher strength gains and reduced peak heat of hydration.
Sellwood Bridge – Portland, Oregon
Category: High Performance
Almost 2,000 feet of concrete pavement, widened lanes, sidewalks and two bike lanes are a part of this bridge replacement project. Slag cement was used at 50 percent replacement of portland cement in mass concrete to lower heat of hydration and had an average strength of over 6,700 psi in 56 days.
St. Croix Crossing – Oak Park Heights, Minnesota
Category: Innovative Application
After many mix designs were tested, the project team felt slag cement was a must for its beneficial effects on compressive strength, freeze/thaw durability, surface scaling, and rapid chloride permeability. The project included more than 200 mass concrete placements, most including 65-70 percent slag cement.
Tampa Airport Taxiway “J” Bridge Reconstruction – Tampa, Florida
Category: High Performance
The Tampa International Airport recently finished the reconstruction of a 300-foot long by 200-foot wide taxiway bridge. The bridge was built to regularly support the weight of Boeing 777 and Boeing 747 aircraft and used a mix design with a 30 percent slag cement replacement of cementitious material.
Zurich North America Headquarters - Schaumburg, Illinois
Category: Green Design
The architectural character of the almost 800,000-square-foot complex uses an interesting material palette, reinforcing the design team’s commitment to sustainability. The mix designs had slag cement replacement percentages from 18.5 percent to 24.4 percent. Overall, slag compromised approximately 23 percent of the cementitious content in the almost 33,000 yards of concrete.
