This investigation was performed to establish the effects of the source and amount of fly ash on abrasion resistance of concrete. A reference concrete was proportioned to have a 28day age strength of… (More)
The coal-fired electric utility generation industry has been identified as the largest anthropogenic source of mercury (Hg) emissions in the United States. One of the promising techniques for Hg… (More)
High-sulfur coal ash, particularly those obtained from clean coal technology, are not extensively utilized in the cast concrete masonry products (bricks, blocks, and paving stones) industry. This… (More)
This project consisted of performance testing and evaluation of foamed Controlled Low-Strength Materials (CLSM). Foam was produced using a commercial foam-generator. The CLSM consisted of a Class C… (More)
High-sulfur coal ash, particularly those obtained from clean coal technology, are not extensively utilized in the cast concrete masonry products (bricks, blocks, and paving stones) industry. This… (More)
Two series, each consisting of seven high-volume fly ash concrete mixtures with conductive carbon fibers, were used in this investigation. The first series of the concrete mixtures contained ASTM… (More)
Two series of laboratory mixtures and four series of field construction mixtures were made to evaluate salt-scaling resistance of concrete incorporating large amounts of Class C or Class F fly ash… (More)
The major objective of this project was to develop technology for high-volume applications of high-sulfur coal combustion by-products generated by using both conventional and clean coal technologies.… (More)
This paper deals with the state-of-the-art information on high-calcium, ASTM Class C fly ash use in cement-based construction materials, such as high-performance concrete, ready-mixed concrete, etc.… (More)
