Comprehensive Steel Fibre Trials Completed
Aleemax Pty Ltd has completed a series of independent trials to evaluate the performance of steel fibres used in concrete reinforcement. These trials involved notch beam testing, a method to assess the post-crack behaviour and material properties of fibre-reinforced concrete. All tests were conducted using a uniform concrete mix and strictly followed the procedures outlined in AS3600:2018, the Australian Standard for concrete structures.
Testing Methodology
The notch beam tests were conducted in accordance with Section 16 of AS 3600:2018, which outlines the procedure for determining the post-crack flexural tensile strength of steel fibre reinforced concrete (SFRC). In addition to specifying the casting and curing procedures, Section 16 details the required beam dimensions, notch geometry, loading configuration, and the method for measuring load-deflection curves. Furthermore, Clause 16.7 mandates the recording of certification details for the steel fibres used in testing. These tests are essential for calculating residual strength and toughness indices, which are critical parameters for assessing the structural performance of SFRC. By maintaining consistent mix designs and controlled testing conditions, Aleemax ensured that the results reliably reflect the comparative performance of each fibre type.
Supplier Participation
Aleemax invited all four major steel fibre suppliers in Australia to participate in the trials.
However, only two suppliers chose to attend and submit samples for testing. This limited participation may influence future industry decisions, as the trials provide a transparent and standardized comparison of fibre performance under identical conditions.
Results and Industry Impact
Initial results from the trials revealed significant differences in the performance of the steel fibres tested. These findings offer valuable insights for engineers, builders, and developers seeking to optimize fibre-reinforced concrete for applications such as slabs and pavements. The data also supports more informed decision-making in material selection for structural design.
