Bosfa® gives the highest priority to protecting the environment.

We are well aware of the environmental impact the concrete and steel industries have on the planet. We continuously strive to minimize our environmental impact by focus on #valueengineering and integrating sustainability at all levels of our business

Bekaert®® was granted an EPD certificate in June 2021 for Dramix® manufactured at our Petrovice plant. We are expecting our Indonesian Plant to have their EPD finalized by June 2022.

Dramix® will support you on your sustainability journey

1. Less concrete + less steel = less CO2

  • Dramix® can reduce the thickness of concrete slabs by 10 to 25%
  • Dramix® can reduce the amount of steel by 30 to 50%

By using less concrete and less steel, you significantly reduce the carbon footprint of your project.

2. Longer lasting concrete elements

  • Flooring – A concrete floor reinforced with steel fibers is more durable and resistant to wear and tear than traditionally reinforced floors.
  • Precast – Precast concrete pipes reinforced with Dramix® steel fibers extend the lifespan of pipe systems by 15 to 20 years, as confirmed by wastewater treatment organizations.

3. No microplastic pollution

  • Dramix® steel fibers deliver a microplastic and pollution-free solution, as is increasingly required by government regulations

4. Sustainable transportation

  • Significantly reduced transportation required compared to traditional mesh reinforcing
  • With a focus on #valueengineering utilizing the additional capacity we get with Dramix® 4D 80/60BG to further reduce the amount of transportation required by getting the most meters out of each container.

5. We are part of sustainable networks

Bosfa want to facilitate transparency and enable our customers to make the best sustainability choice when designing elements and selecting materials and solutions. Dramix® solutions are available in One Click LCA BIM plugins, and commercial tools to support in achieving LCA certification credits such as Green Star, BREEAM, LEED, Levels, DGNB and others.

urban structures seminarWith the recent appointment of our W.A. Manager – Gary Goodall, to the South East Asian (SEA) team, he will give additional support in the Singapore region. The South East Asian market is a very dynamic market for construction with many interesting and alternate approaches to construction coming form the region. Gary was given the opportunity to present at the recent Urban Structures Seminar 2018, with a presentation entitled – “Steel Fibre Reinforced Concrete – The Basics and the possibilities”. The presentation was a great fit with the adoption of SFRC in the region increasing and the differing uses opening up greater opportunities for builders, designers and clients.

We would like to thank the Singapore Concrete Institute and Dr Sabet Bahador for allowing Bekaert® to present at this event.
Should you wish to know more about the presentation or SFRC for your next project, please contact Gary at gary@bosfa.com

After some dramas early on in a new warehouse project, the builder knew that they needed to change the main slabs to a Dramix Fibre Jointless solution to save on time and cost, well yeah, that’s a given.

But when the builder realised they might still be able to reduce the program even further, we were asked if we could also look at a Dramix Combi Slab alternative for the perimeter slab behind the retaining walls. Whilst we could have also reduced the thickness through this area, we had to maintain the existing thickness due to the earthworks already being complete. Our solution allowed them to swap the bottom reinforcing bars with mesh, whilst keeping everything else the same, meaning that in this particular case there wasn’t our usual cost savings available, but that wasn’t the focus.

They loved it, that simple change on a relatively small area of the project was able to squeeze another 3 to 5 days out of the program. A great win for all parties!

Many of the Australian Standards for concrete and concrete related materials have been revised or reviewed in recent times. Further to this there have been other guidelines or codes of practice, such as the Concrete Durability Series by the Concrete Institute of Australia, that have been introduced. To this end the Concrete Institute of Australia is pleased to present a national seminar aimed at “Cracking the Concrete Codes”.

There are several challenges that can be faced during the build process, one of which is ensuring you have the most cost effective, efficient design possible. This is where a Dramix design comes into its own, offering efficiency, reduced jointing, speed of construction just to name a few positive aspects.

logistics1 logistics2

Now that you have your design in place another challenge onsite can be scheduling and ensuring the construction process meets all deadlines.

A valid question to be asking, “Can my fibre supplier meet these deadlines to ensure continuous supply across my project duration?”

This is one of the reasons why BOSFA have been so successful in the Australasian market. With warehousing in 8 of Australasia’s main centres ensuring we can service multiple large projects simultaneously. With the backing of our parent company, Bekaert®, the largest global manufacturers of steel fibre reinforcing in addition to our network of logistics and warehousing across Australasia, we can ensure we meet your project supply deadlines.

Ensure your next project gets the design service and the onsite service it requires, speak to your local BOSFA manager.

Great to see a number of projects that have used a #Dramix design up for awards at the Concrete Institutes Awards night.

New Perth CBD BUSPORT

 

 

Every year in Australasia over 1m m3 of concrete is reinforced with steel fibres.  These are supplied into a wide range of applications such as ground slabs, precast, shotcrete, water retaining structures, tunnel segments to name a few.

Ensuring the steel fibres are manufactured in a quality controlled environment should be seen as a minimum requirement for any steel fibre reinforced concrete (SFRC) specification.  Just as AS/NZS 4671 Steel Reinforcing Materials is specified as a minimum requirement for mesh or bar.

How to specify

  • Fibres should be manufactured in accordance with EN14889-1, system 1 for structural use or, ISO13270 Class A.
  • A Declaration of Performance (DoP) should be supplied to the project engineer or interested party and will be used to check against the CE label attached to delivered pallets of fibre.
  • Fibers without a DoP and corresponding CE label attached to delivered product do not comply.

(both these Standards have been cited in AS 5100.5 as a minimum requirement for steel fibres)

Of course the next important part of any specification is the required performance of the SFRC.  This should either be specified in terms of residual flexural strength, toughness indices or fibre type and dosage if the tendered design is based on a specific fibre.

Depending on the application additional requirements for concrete quality control may be required; fibre batching process, checking fibre distribution, etc.

Please contact BOSFA if you require assistance with design and/or specification.

Background

EN14889-1 Steel Fibres. Definitions, specifications and conformity or, as it’s commonly referred to – ‘CE certification’, is a performance based manufacturing standard used by steel fibre producers.  It sets out the level of quality control required for all the fibre characteristics that influence performance; length, diameter, aspect ratio, E modulus and tensile strength.  Importantly, certification to this Standard is issued by a 3rd party.

There are two types of classification; system 1 for structural use and system 3 for non-structural use.  Structural use is where the post crack residual strength values are used in design, this applies to almost all SFRC applications.  Another requirement of this standard is that producers also need to declare the minimum fibre dosage required to reach a prescribed level of performance.  This provides an independent means to compare the expected performance of fibre types produced by different manufactures.

What documents should be requested to ensure compliance?

The fibre supplier should provide a current CE label (example shown below) and the DoP.  This label is attached to every pallet (also shown below) of Dramix® supplied to the market and can be used as a QC check at the batching plant to ensure the specified fibre is being used.

BOSFA DRAMIX 5D Foundations

DRAMIX? 5D used for footings

How can steel fibres replace steel bars in foundations?

Dramix 5D steel fibre reinforced concrete (SFRC) provides enough capacity to the cracked section to induce strain hardening behaviour in flexure. This means the moment capacity of the section after cracking is greater than the moment when cracking first occurs, enabling Dramix 5D solutions to be used as structural reinforcement in either fibre only solutions or in combination with conventional steel.

The steel fibres we use in structural foundations are unique. Dramix 5D are steel fibres intended for structural use and conforms to the requirements of System 1 of EN14889-1 and Class A of ISO 13270 Steel fibres for concrete.

Strip Footings

Why would you use SFRC to replace or reduce conventional reinforcing?

Two words – speed & cost. For the majority of projects using Dramix 5D steel fibre reinforced concrete to reduce or replace the conventional reinforcing in foundations is significantly quicker and a more cost-effective option than the conventional steel bar or mesh.

Tian presenting in WA

I’d like to thank Dr Tian Ng our engineering manager for travelling to Perth and presenting a very informative and technical presentation at the weeks Concrete Institute’s monthly seminar.

Tian’s presentation covered the development’s within AS5100.5 including the addition of design guidelines for SFRC. He also focused on how these new design guidelines can benefit your designs when combining both SFRC with traditional reinforcement. Extremely useful for structures requiring a specific crack width determination or simply to remove expensive dowel joints and troublesome saw cuts

Tian presenting in WA 2 

Speak to your local BOSFA manager about designing with Combined reinforcement to realise some of the benefits, flexibilities and overall cost savings that can be achieved on your next project.
