The worldof concretehas never offeredso many creativeopportunities3n
“Dramix ® is positive proof thatadvanced technology does makea difference. It enables us toinnovate and create with concrete,reinforcing even <strong>the</strong> mostdemanding structures.At <strong>the</strong> same time, it allows us towork faster and save costs – bothcrucial factors in our business.“Mr. Jumrus KongsiriOwner of J Plus Engineering Consulting Co., Ltd & RegisteredProfessional EngineerBangkok, Thailand
Steel fibres creating new levelsof concrete reinforcement5DDramix®Dramix ®4DDramix®3DDramix®With its brand new range of Dramix ® products, <strong>Bekaert</strong> istaking steel fibre reinforcement to a whole new level.Stronger, safer, and more durable. And even moreconvenient to use. But most of all, opening up a new worldof possibilities for you to create with concrete.An updated and expanded range<strong>Bekaert</strong> has redesigned and expanded its Dramix ® range of steel fibresfor concrete reinforcement. The existing range of steel fibres has beenrebranded as <strong>the</strong> 3D series. It remains widely recognized as <strong>the</strong> bestsolution currently on <strong>the</strong> market when it comes to performance andcost-efficiency. However, with <strong>the</strong> introduction of two brand new fibreseries in <strong>the</strong> Dramix ® range, <strong>Bekaert</strong> is again leading <strong>the</strong> way and takingsteel fibre reinforcement to <strong>the</strong> next level.Unique shapes, unique capabilitiesThe unique shape of <strong>the</strong> new Dramix ® 5D and 4D fibres already speaksfor itself. Engineered to perfection, <strong>the</strong> new Dramix ® steel fibres offerpreviously unavailable levels of anchorage, tensile strength and ductility,guaranteeing maximum performance. At <strong>the</strong> same time, <strong>the</strong>y enable <strong>the</strong>building industry to use steel fibre reinforcement in a wide range of newapplications. Whatever your project, Dramix ® provides you with <strong>the</strong> bestpossible solution.Years of research and innovationAs a pioneer in <strong>the</strong> field, <strong>Bekaert</strong> decided to use all of its know-how andexpertise to take steel fibre reinforcement one step fur<strong>the</strong>r. Because at<strong>Bekaert</strong> we believe steel fibres are now more than ever <strong>the</strong> <strong>future</strong> of concretereinforcement.7n
3DDramix®Often imitated,never equalledDramix ® 3D is <strong>the</strong> new name for<strong>the</strong> existing range of Dramix ®steel fibres, which throughout <strong>the</strong>years has become <strong>the</strong> referencein steel fibre reinforcement.Combining high performance,durability and ease-of-use, 3Dprovides you with a time-savingand cost-efficient alternative totraditional concrete reinforcementsolutions.Over <strong>the</strong> years, <strong>the</strong> 3D serieshas become <strong>the</strong> referencein steel fibre reinforcement,providing high performanceand cost efficiency for mostcommon applications.3DDramix®> Standard tensile strength> Original anchorage11n

Smarter fibres for better concreteIf one fibre can hold up to 100 kilos …… imagine what 180,000 fibres per m 3 can do!Precisely engineered for strength and ductilityFor concrete to be durable, it needs to be both strong and ductile.This is exactly what <strong>Bekaert</strong> aims for with its new Dramix ® series. Bycarefully balancing wire properties – shape, strength, andductility – and combining it with stronger anchorage, <strong>the</strong> new 5D and4D series reach previously unseen levels in concrete performance.All Dramix ® series are available in a wide range of l/d ratios.This enables you to fur<strong>the</strong>r optimize Dramix ® steel fibres for use inyour specific application, to create different types of concrete quality,and to comply with <strong>the</strong> most demanding durability specifications.The 5D fibre has <strong>the</strong> capacity tohold up to 100 kilos, thanks to asmart combination of improvedanchorage and preciselyengineered wire qualities.5DDramix®4DDramix® Dramix ®3DDramix®Anchorage StrengthTensile StrengthWire Ductility100 kgl/d RatioSteel Fibre Concrete StrengthUnique combinations of wire properties and fibre shapes create newperformance levels in concrete reinforcement. Due to <strong>the</strong>ir specificcharacteristics and high performance levels, <strong>the</strong> 4D and 5D series areonly available in glued form and with <strong>the</strong> highest l/d ratios.17n
Designed for durabilityAnchorage strengthThe hooked ends of Dramix ® 3Densure <strong>the</strong> desired fibre pull-out.This is <strong>the</strong> mechanism whichactually generates <strong>the</strong> renownedconcrete ductility and post-crackstrength.The improved anchorage ofDramix ® 4D utilizes <strong>the</strong> sameprinciple but translates it togreater steel strengths.Dramix ® 5D, in contrast, isshaped to form <strong>the</strong> perfectanchor; <strong>the</strong> pull-out mechanismis replaced by fibre elongation.Wire strengthThe tensile strength of a steelfibre has to increase in parallelwith <strong>the</strong> strength of its anchorage.Only in this way can <strong>the</strong> fibreresist <strong>the</strong> forces acting upon it.O<strong>the</strong>rwise it would snap, causing<strong>the</strong> concrete to become brittle.On <strong>the</strong> o<strong>the</strong>r hand, a strongerwire cannot be fully utilized withan ordinary anchor design.Therefore <strong>the</strong> tensile strength of afibre has to be perfectly alignedwith its anchorage system andits diameter. Dramix ® 3D, 4D,and 5D are each designed tocapitalize on <strong>the</strong> wire strengthto <strong>the</strong> maximum degree.Wire ductilityWire ductility and concreteductility are two different aspects.Dramix ® 3D and 4D createconcrete ductility by <strong>the</strong> slowdeformation of <strong>the</strong> hook during<strong>the</strong> pull-out process, and not by<strong>the</strong> ductility of <strong>the</strong> wire itself.This is different for <strong>the</strong>Dramix ® 5D. Due to <strong>the</strong> “perfectanchor” design, <strong>the</strong> fibre cannotbe pulled out and does not movein <strong>the</strong> concrete. Instead <strong>the</strong> wireis elongated, providing <strong>the</strong>ductility on <strong>the</strong> same principleas classic reinforcement steel.This is only possible with asuperior and exceptional qualityof ductile steel wire.5DDramix®Tensile curves 3D-4D-5D wire qualities25005DDramix®20004DDramix® Dramix ®Stress (N/mm 2 )150010004DDramix® Dramix ®3DDramix®5003DDramix®00,00 1,00 2,00 3,00 4,00 5,00 6,00 7,00 8,00Strain (%)The tensile strength of <strong>the</strong> 5D, 4D, and 3D series offers differentperformance levels for different applications.

Make it happen!Dramix ® has enabled building professionals all over <strong>the</strong> worldto overcome major technical, structural, and engineeringchallenges. The result has been some of <strong>the</strong> mostambitious construction projects <strong>the</strong> world has ever seen.CCTV TowerDesigned by architects RemKoolhaas and Ole Scheeren, <strong>the</strong>CCTV Tower has become one of<strong>the</strong> iconic landmarks of Beijing. Thetower serves as <strong>the</strong> headquartersfor China Central Television CCTV).It was officially opened 1 January2008 – in time for <strong>the</strong> SummerOlympics of that year. Constructionof <strong>the</strong> building presentedeveryone involved with majorstructural challenges. It was notjust <strong>the</strong> radical shape and <strong>the</strong>considerable height of <strong>the</strong> tower,but also its location in an activeseismic zone. During construction,steel fibre reinforced concretewas pumped from ground levelto a height of 240 metres.Dramix ® steel fibres were used incombination with rebar and selfcompactingconcrete. Toge<strong>the</strong>rthis created optimal tensilestrength, eliminated cracks, andguaranteed maximum safety.Gardens by <strong>the</strong> BayLocated in <strong>the</strong> heart of <strong>the</strong> city, Gardens by <strong>the</strong> Bay will transformSingapore from a “garden city” to a “city in a garden”. Spanning 101hectares, it consists of three waterfront gardens – Bay South, Bay East,and Bay Central. The largest of <strong>the</strong> three, Bay South, will be opened to<strong>the</strong> public in 2012. Dramix ® was an essential ingredient to guarantee <strong>the</strong>durability of <strong>the</strong> indoor floors.Ski slope SwitzerlandEvery year, thousands of wintersports enthusiasts enjoy thisspectacular new ski slope inEinsiedeln, Switzerland. Dramix ®was used to create <strong>the</strong> perfect,liquid-tight slope.25n
