By Don Marsh
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.

W.R. Grace & Co. has closed on the assets and associated entities of RS Solutions LLC, a West Chester, Ohio, developer of process control solutions for ready mixed concrete producers, including truck-mounted electro-mechanical devices and sensors. RS technologies measure concrete slump during delivery to job sites; they especially enable producers to monitor authorized or unauthorized addition of water—or other changes to the ready mixed as dispatched—that can compromise product quality or spur rejected loads.
