Luke Pinkerton; Chief Technology Officer of Helix Steel; presented a paper titled:– Twisted Steel Micro-Reinforcement (TSMR): Proactive Micro-Composite Concrete Reinforcement;– at the 27th Biennial National Conference of the Concrete Institute of Australia; in conjunction with the 69th RILEM Week. Luke answered two fundamental questions in his presentation: 1) Is it really okay to design fibre concrete assuming large cracks have formed?, and 2) Why do we give up on the concrete so easily? These two questions can be confidently answered because of 10-years of successful implementation worldwide, which has shown that the success of TSMR reinforced concrete is undeniable. This very fact, in addition to the significant increases in modulus of rupture and splitting tensile strength TSMR provides, calls into question common fibre testing and design guidelines that assume the concrete has failed prior to any contribution.
Helix Steel recently earned IAPMO’s Uniform Evaluation Service (UES) Evaluation Report ER-0279 on Helix 5-25 Twisted Steel Micro Rebar (TSMR). Helix 5-25 TSMR 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.
