Cortec’s MCI Creteskin (www.cortecvci.com) is an industrial-strength release agent containing migratory corrosion inhibitors (MCI). It’s designed to protect equipment, vehicles, and forms in the construction industry. This clear coating inhibits the adhesion of concrete, other cementitious materials, salts, and abrasives to painted and unpainted metal surfaces. It also provides corrosion protection to the underlying substrate, enabling continued use and a longer lifespan.

Rapid Set rapid-hardening hydraulic cement products from CTS Cement Manufacturing Company (www.ctscement.com) exceed 3,000 psi in one hour. Rapid Set does not shrink, and it provides high sulfate resistance, chloride resistance, and permanent repairs, according to the company. Type K shrinkage-compensating products allow for installation of industrial-size floors and concrete structures with no curling, no drying or shrinkage cracking, and no control joints.

The Taper-Lock is a taper thread mechanical rebar splice system offered by Dayton Superior (www.daytonsuperior.com). Taper-Lock provides a Type 2 mechanical splice for use in tension, compression, and cyclic applications. Taper-Lock is approved in most states and has an ICC ESR 2481 report.

Acoustic Concrete Tester from Inspection Instruments, Inc. (www.inspectioninstruments.net) evaluates concrete bridge decks, pavements, retaining walls, slabs, tunnel liners, and footings without coring. Light and simple to use, it quickly examines if a concrete element is built to the specified thickness and aids in reassuring that it is free of flaws. It also features ultrasonic echo technology.

Kelken (www.kelken.com) manufactures structural chemical anchoring adhesives and anchors for a variety of applications.

LUSAS (www.lusas.com) bridge analysis software was successfully used on the Dubai Metro Light Rail project to model concrete viaduct structures. This involved seismic analysis to AASHTO LRFD and the calculation of design moments from seismic and modified load combinations to a United Kingdom code for use with pile and pier design.

Midas FEA (www.midasuser.com), Detail FE Analysis, provides finite element analysis with built-in CAD geometry modeler and auto-mesh generators, linear, nonlinear material/geometry/interface, nonlinear concrete crack, reinforcement and tendon-in-shell/solid elements, fatigue, linear dynamic, construction stage, and buckling analyses. Midas Gen 2010 Building and General Structures provides analysis of static, dynamic, pushover, inelastic time history, material/geometry nonlinear, masonry structures, cables, pre/post-tensioning, time-dependant material models, column shortening, construction stage, and heat of hydration analyses. Midas Civil 2010 Bridges provides 3D analysis and design for curved/straight girder, composite, segmental post-tensioning, suspension, cable-stayed, skewed slab, frame, arch, and culvert bridges with live-load optimizers.

According to Universal Forest Products Inc. (www.ufpiconcrete.com), one of the best methods to achieving proper cement hydration, reducing discoloration, and producing highly wear-resistant concrete floors other than wet curing is through the use of its patented UltraCure brand. These wet curing blankets outperform other curing blankets by laying flatter on the surface and offering superior water retention, which allows the concrete to achieve optimal hydration for the entire curing period. The traditional use of wet curing concrete flooring can add as much as 25 percent to the life of the slab.
