Case study - High volume fly ash in the Madera project
Located on a fully wooded 44-acre site in Gainesville, Florida, directly adjacent to the University of Florida campus, Madera consists of 80 lots being developed by Green Trust, LLC, and built by three builders. In the spring of 2002, selected builders were invited to participate in a presentation and meeting with the Florida Energy Extension Service (FEES) which spearheaded the project for the ...

Case study - Fly ash concrete modified strength projects
In order to remain current with sustainable concrete design and construction practices, it is becoming more important to enable ready mix producers to supply innovative performance mixes that contain optimum percentages of fly ash. These mixes can be used to meet sustainable development practices, durability and exposure requirements, associated life-cycle costs, LEED building credits, economic ...

Case study - Point Mugu Naval Airstrip
The runway is located at the Point Mugu Naval Air Station in Southern California. Economy, durability, low shrinkage and high strength were accomplished by reducing the amount of portland cement used in the concrete while utilizing large volumes of fly ash. In addition to field performance, this approach provided the added environmental goal of reducing the CO2 released into the air through ...

Case study - Fly ash concrete design for Chicago’s 100-year road structure
After years of heavy use, Wacker Drive, a major two-level viaduct in downtown Chicago, Illinois needed to be rebuilt. The Chicago Department of Transportation (CDOT) set ambitious goals for the $200 million concrete structure because of its central location and importance to downtown traffic flow. The end result is a more durable roadway with a service life of 75 to 100 years. Originally built ...

Case study - High volume fly ash for Texas parks building
Before construction began on the new park headquarters building at Lake Somerville State Park, the Texas Parks & Wildlife Administration decided it had a great opportunity to get involved with sustainable building practices. Using High Volume Fly Ash (HVFA) in concrete structures at the site was one of the main sustainable building components used in the project. Although it was a relatively ...

Full probabilistic service life prediction and life cycle assessment of concrete with fly ash and blast–furnace slag in a submerged marine environment: a parameter study
Nowadays, more attention is being paid to sustainability in construction. Over the years, the concrete research community has developed a wide range of potential 'green' concretes. To reduce cement related CO2 emissions, a considerable part of the traditional binder can be replaced with industrial by–products. However, as a result of the current focus on comparative durability assessment based on ...

Case study - High volume fly ash for the 2 Folsom project
High Volume Fly Ash (HVFA) concrete was successfully used as the cornerstone of this project’s sustainability program. HVFA concrete was aggressively pursued because of its environmental benefits. When fly ash is used in place of cement, energy and landfill space is conserved and greenhouse gas emissions are reduced. During this HVFA project, roughly 2,800 tons of CO2 emissions were ...

Fly Ash & the Lightweight Aggregate Market
In 2015, the global fly ash market was estimated to be valued at 40 billion USD. A recent industry analysis by Research Nester anticipates the market will reach an estimated 70 billion USD by the end of 2023 – a 7.1% CAGR owing to increasing urbanization and a boost in construction projects. Along with bottom ash (BA) and flue gas desulfurization gypsum (FGD gypsum, or synthetic gypsum), ...

Durability evaluations of bridge deck high–performance concrete
Although several information are available on various aspects of durability of high–performance concrete (HPC), no systematic information is available on durability of HPC used for bridge decks. In this study, 12 HPC mixtures were prepared with different combinations of fly ash, slag, and silica fume with three different w/cm ratios: 0.40, 0.35, 0.30 to study the durability primarily ...
