Title:  Steel Fibre Reinforced Concrete Design & Construction to AS 3600-2018

Presentation Outline:
In June 2018, the revised Australian Standard AS 3600 released. This presentation outlines  the AS3600 design and construction provisions for Steel Fibre Reinforced Concrete for use in structural application. Structural steel fibre reinforced concrete applications differ mainly from well-known fibre applications like floors and pavements. In structural applications, steel fibres are the main or the secondary reinforcement to take up bending moments and the shear stresses. This presentation will discuss some basic principles governing the structural design of SFRC based on the available design codes. Starting from the classification of various types of steel fibres, which have profound effect on the performance of concrete structures, the simple constitutive models are presented, allowing engineer and designer to design with Steel Fibre Reinforced Concrete. A few case studies will be presented, giving insight information on where steel fibre reinforced concrete can be used.

Title:  Properties of Ambient Cured Geopolymer Concrete Reinforced with Different Types of Steel Fibres

Presentation Outline:

The influence of different types of steel fibres on the engineering properties of ambient cured geoploymer concrete is presented. The properties investigated include workability, compressive strength, splitting tensile strength, flexural strength, direct tensile strength, and stress–strain response under axial compression. Three types of steel fibres were used, straight micro
steel fibre, deformed macro steel fibre and hybrid steel fibre. Results show that the workability of the geopolymer concrete decreased with the increase in the steel fibres. Also
the compressive strength, splitting tensile strength, flexural strength, and direct tensile strength of the geopolymer concrete increased with the addition of steel fibres.
The addition of hybrid steel fibre (1% straight microsteel fibre plus 1% deformed macro steel fibres) showed the best improvement in the mechanical properties of geopolyer
concrete.
