The below papers and articles detail some of the ways that Helix Steel has been proven in the field.
Luke Pinkerton, Yamil Moya, and Mahmut Ekenel describe a way to develop alternative methods for designing concrete in compliance with current building codes in the United States.

Luke and Jayendra “Jay” Patel (Senior Structural Engineer with Haskell) encourage the concrete industry to improve environmental outcomes and the competitiveness of concrete as a structural system by using advanced analysis, materials, and methods to design plain concrete in structural ground-supported slabs.
Matthew Pierson and Luke Pinkerton presented this paper which describes and evaluates a direct tension test of fiber-reinforced concrete that is being developed in ASTM Subcommittee C09.42 on Fiber-Reinforced Concrete at the ASTM Symposium on Standards Development for Cement and Concrete for Use in Additive Construction held virtually on December 7–8, 2020.
Concrete pavements reinforced with Twisted Steel Micro Rebar (TSMR) perform in severe environments at half the thickness as plain concrete with the same design equivalent axle load requirements.
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.
Recently presented at Shotcrete 2015 in Austria, this document details the use of Twisted Steel Micro Rebar (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.”

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.
“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.”
