Report measures structural precast versus C-I-P concrete, steel
Sources: Freedonia Group, Cleveland; CP staff Structural building components lead annual precast shipments and are on pace to exhibit nearly 6 percent annual growth over the next five years, according to “Precast Concrete Products,” a new analysis from market researcher Freedonia Group. When specified for slabs, columns, foundations, or full building systems, precast concrete reduces costs in certain construction conditions…

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.

Meadow-Patch Smooth-Grade is a one-component, polymer-modified formulation imparting an ultra-smooth finish on precast, cast-in-place, tilt-up and other plain concrete surfaces or concrete masonry. The cement-based, sand-free material, product developers note, offers superior adhesion and durability; contains no added gypsum; allows vapor to readily pass through the surface; makes troweled applications easy with its smooth consistency; and, offers an extended pot life that allows for an increased working time over traditional concrete surface finishers.
