A New York investor announced at World of Concrete (January 18–21, Las Vegas) technology economizing the grinding of fly ash, or secondary grinding of portland cement, to 3- or 1-micron median particle sizes. With $30–75/ton processing plus $20–100/ton raw feed (fly ash, Type I/II portland cement) costs, the technology can yield premium binding agents whose performance properties in concrete and grouts match those of ultra-fine high-reactivity metakaolin or silica fume—typically commanding $300–$700/ton.
