Frontier Kemper Constructors Inc., a Tutor Perini subsidiary, selects Helix Steel as the concrete reinforcement technology provider for the Metro Transit Authority's East Side Access Project. The MTA’s East Side Access project, the nation’s largest public transportation project and the first expansion of the Long Island Rail Road in more than 100 years, will connect the rail line via underground tunnels to Grand Central Terminal in Manhattan.

Article published in Concrete Engineering International - January 2015 - Helix customer Colorado Precast is the spotlight with their 15,500 gallon tanks. These tanks are now reinforced with a Helix Hybrid design drastically reducing the required rebar and labor time.

Intro from the article: "When Colorado Precast Concrete Inc. manufactured the first of what it calls its “hybrid tanks,” it was for a single order. The idea was to use a minimal cage to affix the anchors needed for moving the 15,500-gallon precast concrete tank in tandem with steel fiber reinforcement to replace the rest of the traditional reinforcement. This provided the necessary strength while reducing the time the form was in use."

Intro from the article: "HIGHLANDVILLE, Mo. -- Many here in the Ozarks know it as that 'giant castle' in Christian County. A lot of people also have their opinions about why Pensmore Mansion is being built and what's going on behind its walls. KOLR10 got a look inside the mega mansion and spoke with its owner who said he hopes people focus more on the structure's cutting-edge construction, rather than the conspiracy theories."

This report accredits Helix Micro-Rebar 5-25 and its design method under ISO Guide 65 for use as an alternative to conventional rebar and wire mesh in concrete. Helix Micro-Rebar 5-25 is the only discontinuous concrete reinforcement product in the world that now has a ISO certified design manual that can be followed to design vertical applications (such as walls) with Helix as the primary concrete reinforcement.

Presented by Luke PInkerton in Australia at the Concrete 2015 conference, this paper discusses the following: "TSMR provides proactive reinforcement as, unlike conventional reinforcement and other forms of reinforcement, it engages the material before it actually fails. Similar to conventional methods of reinforcement, TSMR also provides reactive reinforcement as it continues to provide stable tensile resistance after the concrete’s strain capacity is exceeded." In addition, "The authors present a simple design method to determine the necessary TSMR dosage to resist the tensile forces in an area of concrete equal to or greater than the conventional reinforcement."

Recently presented at Shotcrete 2015 in Austria, this document details the use of Twisted Steel Micro-Reinforcement (TSMR) for shotcrete applications. Taken from the introduction of the technical paper, "Steel fibers have been used to reinforce shotcrete, replacing traditional steel wire mesh, for over twenty years. They are added to shotcrete to improve energy absorption, crack resistance and provide ductility. All three properties are very important for support systems designed for tunnel and mine conditions. TSMR (Twisted Steel Micro Reinforcement), takes shotcrete reinforcement one step further."

From the introduction, "In this project, CIES (Centre for Infrastructure Engineering and Safety) at School of Civil and Environmental Engineering (CVEN) of the University of New South Wale (USNW) has collaborated with Helix Steel Australasia Pty Ltd on an investigation of the bending an shear behaviors of circular concrete piles reinforced with Helix TSMR (Twisted Steel Micro Rebar )plus a N16 or N20 bar at the pile center."

A “microscopic” composite can be created by combining concrete with HELIX™ twisted steel micro reinforcement (herein referred to as micro-reinforcement). As this type of reinforcement is distributed throughout the matrix and is continuously deformed like reinforcing bars, it carries load both before and after the concrete develops a macro-crack. Thus, micro-reinforcement is proactive reinforcement that also acts as reactive reinforcement at higher strain levels.

Published by The Concrete Society in the United Kingdom, this article provides a description of the fractural mechanisms of micro-reinforced concrete composite, a novel method to measure performance characteristics of the composite and the ISO Guide 65 (1)/IAF-accredited HELIX micro-reinforcement design method for structural concrete. From the article: "A “microscopic” composite can be created by combining concrete with HELIX™ twisted steel micro reinforcement (herein referred to as micro-reinforcement).

From the abstract, "This is an experimental investigation focused on the study of the effect of addition of helix fibers in plain concrete to evaluate the compressive strength, tensile strength and the modulus of elasticity when compared to normal concrete."
