Prevent bacteria and corrosion in pipes
ConmicShield is an EPA-registered, anti-bacterial additive that prevents micro-biologically induced corrosion (MIC) from deteriorating concrete pipe and manholes in sewers. Protective coatings and plastic liners can disbond and pinhole, allowing corrosion to form, while ConmicShield is an integral component of the concrete. When bacteria contacts this concrete, their cell structure ruptures and the organisms die, breaking the MIC chain of corrosion.

It weighs 3.5 pounds, has an IP65 protection class, and an internal antenna. Cattron Group International. 724-962-3571. www.cattrongroup.com.Precast Show booth #1658.
Reclaimer for precasters
The Model M6 Reclaimer is ideal for equipment clean-up and wash-out, and handling the leftovers or the occasional bad batch. A rotary screen delivers clean rock to one stockpile, and a sand dewatering screw conveys clean sand to a separate pile. The M6 can be installed with a STAR prefeeder/hopper assembly, allowing two yards of concrete to be dumped at once. BFK Technologies. 888-235-8235. www.bfktechnologies.com.Precast Show booth #307.

Steel fiber reinforcement
Dramix Green steel fiber for precast concrete offers high ductility and a solid structure for a better load-bearing capacity and impact resistance than mesh. Concrete with Dramix Green fills molds easily and completely, even for complex shapes and thin walls. The even dispersion of its corrosion-resistant fibers in concrete results in a rust-free surface.

AV-200 Dura-Set is a two-component liquid polyurethane elastomer grout that may be sprayed, injected, or trowelled onto a surface. It combines strength and elongation with chemical resistance to create a flexible rubber that is unaffected by water or UV rays. The product is part of a line of chemical grouts that stop water infiltration, stabilize soils, encapsulate hazardous waste, and seal sewer and underground transit systems.

Making the Connection
With the stakes higher than ever to get jobs on the books for 2009 and beyond, precasters want to give customers every reason to choose their products over other building materials. Concrete inserts are one way to make specifiers' and contractors' lives easier. Available in a range of sizes and styles, inserts secure connections between precast elements and facilitate field erection. This allows architects and engineers the freedom to incorporate more precast into their designs, especially on large-scale projects. The following products make precast construction easier.
Cast metal pockets
The new QLOK System copes with harsh wintertime construction. This system secures adjacent precast members together by cast metal pocket modules. Flanged bolts are inserted through pocket module cavities into pre-aligned threaded couplers in the adjoining member. When bolts are tightened, concrete surfaces are compressed to increase shear friction. Barsplice Products. 937-275-8700. www.barsplice.com.Precast Show booth #764.
