A-Lok looks past steel to basalt fiber reinforced polymer rebar

As composites of fibers embedded in polymeric resins, fiber-reinforced polymers (FRP) have emerged as an alternative to steel for concrete reinforcing bars, offering weight savings, strength and corrosion-rooted durability advantages, and longer service life. Manufacturing advances have positioned FRP rebar as competitive with conventional steel reinforcement, and very competitive with higher performance epoxy-coated and stainless steel rebar, according to A-Lok Products.

Wausau Tile and Iowa Mold Tooling: A delivery solution

Precast site furnishings common in settings from municipal streetscapes to McDonald’s and Target locations positioned Wisconsin’s Wausau Tile among the first producers to establish a national concrete brand. One of the key means of supporting and building that brand is a delivery service catering to non-contractor customers who are not equipped for heavy lifting or repairing concrete damaged in transit.

Pneumatic deflection elbows cut wear, dust, offload time for bulk handling

San Antonio-based Robert Ober & Associates is a design/build firm serving an international client base for bulk material handling projects that range from $25,000 retrofit contracts to $25 million turnkey plant projects. Its early focus on pneumatic handling for concrete plants has grown to include a wide range of material transfer, weigh batching, and powder blending systems in other industries. About 60 percent of that focus is on new plant designs, the remainder on retrofits.

Elematic program executes continuous hollow core production

The FloorMES E9 is a hands-on tool for supervising and planning precast floor element production. The automated manufacturing execution system (MES) from Finland’s Elematic Oyj and Wisconsin-based Elematic Inc. optimizes and balances the production plan and schedules; monitors work process against the original plan; and, engineers note, spells an end to manual processes and paper piles that have accompanied hollow core fabrication.

CarbonCure equips Thomas Concrete to replace cement with recycled CO2

A breakthrough process for ready mixed gives John Cook, director of Technical Services at Atlanta’s Thomas Concrete, cause for enthusiasm this construction season. In late February, he and his team oversaw the installation of the CarbonCure Ready Mixed Technology at their Doraville, Ga. plant. They immediately began the process of lowering cementitious material content and dosing concrete mixes with carbon dioxide (CO2) gas using the CarbonCure injection system. Later in March, Cook and colleagues eagerly reviewed the 28-day strength data and confirmed: CO2 may be used as a viable cement replacement.
