BDAT stabilization technologies include “lime/fly ash mixtures, cement, concrete mixtures, or other proprietary or non-proprietary formulations”. ...
Fortunately, fly ash can be used as a beneficial additive in some applications – particularly in concrete products, where it is used as a lightweight aggregate (LWA).The benefits of using fly ash as a lightweight aggregate in concrete products are so great that the concrete ...
Previous methods of stabilization, including pole slide pilings, lime-fly ash injections, and concrete caps had all failed to provide long-term track stabilization. ...
To provide resistance against future corrosion, Class F fly ash was selected as a proven existing technology along with other materials to enhance the new cast-in-place concrete structure. ...
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 cement production by replacing as ...
The project was also expected to increase homeowners’ awareness and utilization of energy-saving and recycling practices. High volume fly ash (HVFA) concrete is one of the technologies used in the project to promote resource-efficient construction. ...
Building materials used included FlexCrete aerated concrete block, fly ash based mortar, fly ash based stucco, synthetic wall board, fly ash backed carpets, acoustical ceiling tile, shingles, ceramic tile, cultured stone, and high volume fly ash ...
High Volume Fly Ash (HVFA) concrete was successfully used as the cornerstone of this project’s sustainability program. ...
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 ...
Current language by the American Concrete Institute committee 232 on “Fly Ash and Natural Pozzolans” further reinforces and clarifies the beneficial use of fly ash to reduce sulfate expansion and attack. “As a general rule, Class F fly ash can improve the ...
From the visually breathtaking use of shotcrete to create the architectural features of rocks and trees in the Ocean Journey complex, to the 8,500 cubic yards of high performance concrete for the salt-water tanks and the structure in general – all benefited from the use of Headwaters Resources fly ash. ...
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. ...
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, ...
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. ...

The paper mentions very briefly the development of high-performance, high-volume fly ash (HVFA) concrete that incorporates large dosages of superplasticisers. The use of HVFA concrete can reduce very significantly the use of cement in concrete, thus contributing to the reduction in the greenhouse gas emissions. ...
These areas will be fed with rainwater and stormwater run-off that has been captured thru openings in the concrete paver surface that has been filled with open-graded aggregates. ...
