Steel reinforcing fibers: Micro Rebar

97 Helixi 150Product developers characterize Helix 5-25 Micro-Rebar Concrete Reinforcement System as the only code approved material of its kind engineers can confidently specify as a replacement for primary structural reinforcing. Micro-Rebar are .5-mm diameter, 25-mm (1-in.) long fibers of twisted, high tensile (246 ksi), zinc-coated steel wire, dosed at 9 lb. to 70 lb. per cubic yard of concrete. Each pound of product has about 11,500 fibers.

Building enclosures

96 Clear 150Company has added the Metal Building series to its line tension fabric structures for plant or storage enclosure solutions. It offers steel side walls with the integrity of the company’s Hercules Truss Arch frame. Since there are no internal support posts, the building allows for maximum usable space. The metal building is design-built to any need and can be engineered to meet any required building codes or snow/wind loads.

Curing compound

96 Chem 150EZ Strip Cure DR is a water-based, low-VOC, low-odor formulation that cures concrete to ASTM C309 and AASHTO M 148 standards. Unlike other dissipating cure products, product developers contend, it does not require UV exposure—making it suited to either indoor or outdoor use. It is easily removed with light mechanical or hand abrasion after curing is complete. Low pressure water spray can be used for removal in outdoor conditions.

HPC, GFRC admixtures

96 Fishi 150Company has added three high performance formulations to a product line encompassing concrete admixtures, sealers and molds. Super-SIX-Admix is a proprietary blend designed to achieve a pinhole free, dense and strong concrete mix that will free flow in precast molds or shape to a superior finish and crisp detail. The formulation suits ultra high performance concrete mixes of self-flowing consistency or with shapeable, clay-like properties for molding, carving or rolling.

Structural thermal blocks

96 Schocki 150A 15-story South Side development designed by Studio Gang Architects scheduled for completion this year, City Hyde Park is the first major Chicago project to incorporate Schöck Isokorb structural thermal breaks. The devices will be used in four concrete balconies, where they minimize thermal outflow and energy loss—contributing to energy savings, while providing occupants added thermal comfort for the residents. Schock engineers note that they effective thermal insulation methods reduces the risk of high levels of condensation, mold formation and associated damage caused along the ceiling slabs interior of the balconies.
