April 2022 Better Materials, Better Designs, Better Ways to Build with ConcreteGo to Structure Magazine
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.
December 2020 Direct Tension Testing of Plain and Fiber Reinforced Concrete for Use in Additive ConstructionSee it at ASTM
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.
October 20, 2017 Twisted Steel Micro Reinforcement Pavements with Unprecedented Thickness ReductionView PDF
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.
August 30, 2015 TSMR: Proactive Micro-Composite Concrete ReinforcementView PDF
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.
January 30, 2015 Twisted Steel Micro Rebar (TSMR) for ShotcreteView PDF
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.”

“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
June 1, 2014 Twisted Steel Micro Reinforcement: Advantages of Microscopic CompositesView PDF
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.
December 01, 2012 NITK Research Bulletin – Experimental Studies on the use of Helix Steel in ConcreteView PDF
“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.”
