A land transaction and product design certification have positioned Tindall to proceed on schedule with a $60 million-plus plant dedicated to the Atlas Concrete Tower Base (CTB). An engineering innovation enabling wind farm operators to extend turbines to a 325- to 460-ft. (100- to 140-meter) height range—extracting more power than shorter structures currently operating—the CTB comprises precast concrete staves, 87 ft. long and tapering from a 14-ft. base to 3.5-ft. top width. Sized for highway or rail hauling, the pie-shaped staves form robust 10-, 12-, 14-, or 16-piece cones. Along with a post-tensioned precast concrete tube section securing turbine masts, the cones bear on a simple ring foundation that requires about one-third the concrete of a standard ground-anchored structure.

A company known for packaged dry or pre-mixed concrete repair or mortar geared to specialty applications has announced a ‘carbon neutral system’ of liquid or powder agents imparting Types I–V portland cement performance characteristics in 100 percent fly ash binder mix designs.

With a green light-basked polar bear as trademark, Ceratech unveiled Ekkomaxx at the 2011 Precast Show (January 27–29, Charlotte, N.C.), noting initial testing efforts in manufactured concrete, where producers have greater control over specifications than their counterparts in ready mixed. The company is promoting the technology’s potential for rapid deployment at existing plants, with Class C fly ash charged from dedicated silo compartments and five Ekkomaxx admixtures dispensed from conventional ground or floor tanks.

Lafarge Director of Research & Development Pascal Casanova is scheduled to join Columbia University Graduate School of Architecture, Planning and Preservation officials in New York City for a February 10 launch of Solid States: Changing Time for Concrete. The book assembles a diverse group of experts to examine the re-emergence of concrete at the intersection of materials science, engineering and architectural practice, and urban history and design. It coincides with what authors contend are technological developments and growing demand for natural resources that further highlight concrete’s pivotal role in transforming architecture and urbanism across the world.
