Tindall schedules production of C-I-P, hollow core slab alternative

The Tindall Superior Lightweight All-Purpose Beam (T-SLAB) is presented as the first and only system of its kind—a precast solution affording superior performance and constructability over both cast-in-place and prestressed hollow core plank. Fabricated in up to 12-ft. widths, T-SLAB seizes on arch design principles by using super lightweight concrete to serve as blocks over which structural concrete is poured, leveraging the arch effect translationally for load distribution, while capitalizing on longitudinal prestressing for total span capability. Several slab thicknesses will be available to achieve optimal spans in the 30- to 45-ft. range, supporting typical commercial and residential floor loads.

LafargeHolcim, GE Renewable Energy turn 3D-printed turbine pedestals

The latest target in a LafargeHolcim Ltd. investigation of 3D-printed concrete elements or structures is a pedestal for a new class of turbines, 150-200 meters high, that have the potential to harness one-third or more energy than the shorter towers dotting wind farms the world over. After participating in a 10-meter scale model printing late last year, the Swiss concrete, cement and aggregates giant has entered a partnership with GE Renewable Energy and Copenhagen-based COBOD International A/S to develop supertall wind turbines with optimized, 3D-printed bases. GE Renewable Energy will provide expertise related to turbine design, manufacture and commercialization; COBOD, short for Constructing Buildings on Demand, will focus on robotics automation and 3D printing assemblies; and, LafargeHolcim will refine the concrete material or ink, along with its processing and application methods.
