Concrete Reinforcing Fibers
Fibermesh Logo

SikaFiber offers a complete line of fiber solutions to deliver stronger, reliable reinforced concrete to the jobsite. Sika is the expert in concrete fibers.

SikaFiber & Fibermesh Product Technology

Fibers are an ideal ingredient for use in concrete and mortars as a method for improving these materials where they may otherwise have weaknesses. Concrete fibers reduce shrinkage crack formation and crack widths whilst also increasing performance in energy absorption and fire resistance. Additional benefits such as reduction or elimination of reinforcing steel and increased durability can also be seen. Applications with concrete fibers have expanded and new fiber materials are also increasingly capable of replacing traditional fibers such as steel and glass.

In 2018, Sika® has acquired the global Concrete Fibers business from Propex Holding, LLC, which includes a US plant manufacturing synthetic fibers for use in concrete reinforcement, sales operations across Sika’s geographical regions, and Fibermesh® a strong brand in FRC. The acquired business was the perfect addition to Sika’s concrete admixture product lines making Sika® a true single source supplier for all ready mix and precast concrete applications. With the addition of Fibermesh®,Novomesh®, Novocan®, and Enduro® to Sika’s product portfolio, Sika® can better supply the needs of concrete customers, engineers, general contractors, owners, and architects.

Concrete Reinforced Fibers
KEY FRC BENEFITS
  • Reduced incidence of early age plastic shrinkage cracking
  • Improved load capacity and ductility
  • Protection against freeze-thaw cycles
  • Better cohesion in the fresh concrete
  • Increased abrasion resistance
  • Higher flexural and shear strengths
  • Reinforcement replacement
  • Joint Extension

Concrete fibers have an innumerable amount of applications in concrete construction. Not only will benefits in fresh and hardened properties be seen, secondary benefits will be made as well. By reducing or replacing traditional meshes and steel reinforcement, labor costs will be reduced and construction schedules can be accelerated. Safety is increased by reducing the chances of tripping or impalement by traditional steel reinforcement. With concrete fiber being integral (well mixed) throughout the concrete, there is no opportunity for reinforcement to end up in the bottom of your slab.

Key Application Benefits
  • Integral Reinforcement
  • Increased safety
  • Less opportunities for callbacks
  • Long term durability increase
  • Reduction in labor for placement of reinforcement
FIBER TYPE

The first step to choosing the right fiber is to understand the type of fiber required for your application. The main standards for fiber reinforced concrete are ASTM C 116 and EN14889. ASTM C 116, Standard Specification for Fiber Reinforced Concrete, outlines four (4) classifications for fiber reinforced concrete:

  • Type I - Steel fiber-reinforced concrete or shotcrete (ASTM A820)
  • Type II - Glass fiber-reinforced concrete or shotcrete (ASTM C1666)
  • Type III - Synthetic fiber-reinforced concrete or shotcrete (ASTM D7508)
  • Type IV - Natural fiber-reinforced concrete or shotcrete (ASTM D7357)
SYNTHETIC MICRO-FIBERS

Micro fibers have a diameter that is less than 0.3 mm. Micro fibers are either monofilament or fibrillated. Micro fibers should be used for plastic shrinkage control (cracking that can occur in the first 24 hours of concrete cure), impact protection, and reduction of explosive spalling during a fire. The fibrillated micro fibers are often used in replacement of the lightest welded wire fiber (6x6 W1.4/W1.4) for temperature and shrinkage characteristics.

SYNTHETIC MACRO-FIBERS

Structural macro fibers have a diameter greater than 0.3 mm. Macro fiber are used as a replacement for temperature and shrinkage reinforcement (WWF) or as structural reinforcement in concrete or shotcrete. Macro fibers are used where an increase in residual (post-cracking) flexural strength is required (ASTM C1609 or EN14845).

STEEL FIBERS

Steel fibers may be collated (glued) together in a clip. The collation of the fibers does not improve performance of the fiber reinforced concrete. Collated fibers improve the ease of mixing of high aspect ratio fibers. Collated fibers are added to the concrete mix, the bundles are spread throughout the concrete. Continued mixing action breaks apart the clips to let the individual fibers separate quickly throughout the mix.

FIBER PERFORMANCE

Fiber performance is influenced by three characteristics; tensile strength, aspect ratio (calculated as the length/diameter) and anchorage (hooked, crimp, emboss, fibrillation, etc.). One characteristic does not outweigh another; all three items have to work together for optimal performance.

Fiber reinforced concrete is a composite material and therefore, all fibers are tested in the concrete to prove their performance.

Fibers begin to function in a structural supportive manner when the concrete matrix starts to crack, just like traditional reinforcement. The crack has to occur for the load to switch from the concrete to the reinforcement. The fibers then provide ductility and support by bridging cracks and thus providing post crack strength to the concrete.

BEST USE OF THE DIFFERENT TYPES OF FIBER
State of concrete or mortar Effect/property improvement Recommended fiber type
Fresh Reduce Rebound of Shotcrete Micro-PP fibers
Fresh Homogeneity improvement Micro-PP fibers
Up to 24 Hours Early-age cracking reduction Micro-PP fibers
28 days hardening or more Improvement of fire-resistance Micro-PP fibers
1-2 days Reduction of cracks induced by restraint or temperature Micro & Macro-PP fibers
28 days hardening or more Transmission of external forces Macro-PP & Steel fibers
Durability Enhancement
Air Entrainers

Air entrainment in concrete is a necessity for any areas which will experience cycles of freezing and thawing. By adding in consistently sized and spaced air bubbles at the correct percentage, durability of concrete is dramatically improved. Sika’s line of air entraining admixtures comply with the standards set forth in ASTM C260.

Corrosion Inhibitors

Rebar is utilized in concrete to provide it tensile strength, however, if not properly protected this rebar can corrode and cause concrete to crack and break apart. Sika CNI and Ferroguard technologies can help protect this from happening.

Shrinkage Reducing Admixtures

Concrete shrinks! Over time through chemical and drying shrinkage concrete changes volume and these volume changes can cause it to crack. The use of Sika Control SRA’s can help prevent cracking and reduce shrinkage.

Silica Fume

Silica fume is an extremely fine powder that when utilized in concrete can help provide high strengths. SikaCrete products help densify concrete making it more resistant to mechanical abrasion and chemical ingress.

Sikacrete®-950 DP

Densified Silica Fume Powder
How It Works: Sikacrete®-950 DP is a pozzolanic material that consists primarily of fine silicon dioxide particles in a non-crystalline form. Silica fume particles have a diameter of less than 1μm; about 100 times smaller than the average cement particle.    Pozzolanic action: A chemical reaction takes place between the free lime Ca (OH) 2 in the cement paste and the microsilica particles which results in the formation of additional calcium silicate hydrate (CSH) gel, the glue that holds the concrete constituents together. The formation of this extra binding force within the gel increases the compressive and flexural strength of the concrete.   Void Reduction: The fine particles of Sikacrete®-950 DP fill the tiny voids and capillary pores within the cement matrix and significantly reduce porosity to produce an extremely dense and impermeable concrete.     Advantages: Sikacrete®-950 DP produces concrete that has dramatically increased compressive and flexural strength, which allows greater design flexibility and structural design economies, combined with reduced permeability to increase the service life of the concrete.    
  • Compressive strengths are dramatically increased for high performance concrete.
  • Excellent abrasion and erosion resistance increases concrete durability in high-traffic areas.
  • Permeability is dramatically reduced, which makes microsilica ideal for applications where concrete will be required to resist chemical attack.
  • Resistance to corrosion is increased because concrete is more resistant to water ingress and therefore also to corrosion caused by sulfates and water-borne chlorides such as deicing salts.
  • Decreased permeability gives microsilica concrete excellent freeze-thaw resistance because less water is trapped inside the cement paste.
   Sikacrete®-950 DP does not contain calcium chloride nor any other intentionally added chloride containing ingredients.
Metakaolin

Metakaolin is highly reactive calcined clay. It is amorphous; meaning it chemically reacts with the hydration products of concrete to reduce its permeability and improve its strength and durability.

Sikacrete® M-100

Metakaolin Powder
How it works: Sikacrete® M-100 is a pozzolanic material, it is produced by thermally activating kaolin clay to produce an amorphous and chemically reactive material. Unlike other supplementary cementitious materials like flyash, slag and silica fume, Sikacrete® M-100 is not a by-product, it is specifically manufactured to its specification that improve the properties of concrete. The average particle size of Sikacrete® M-100 is 5 μm.    Pozzolanic action: Sikacrete® M-100 reacts with the free lime, Ca (OH)2 produced during the hydration process of cement to produce Calcium Aluminates and additional Calcium Silicate hydrates which is responsible for the strength of the cementitious mixture or concrete.   Void Reduction: The fine particles of Sikacrete® M-100 fill the tiny voids and capillary pores within the cement matrix and significantly reduce porosity to produce an extremely dense and impermeable concrete.   Advantages:
  • Increased early and later age compressive and flexural strength, which allows flexibility in structural design and allows early stripping of forms.
  • Increased resistance to bleeding and segregation.
  • Improved abrasion and erosion resistance, which increases concrete durability in hightraffic areas
  • Reduced permeability, which increases durability, resists chemical attack and increases service life of concrete.
  • Improved corrosion resistance, due to reduced chloride ingress in concrete.
  • Improved concrete performance in freeze thaw conditions.
  • Reduced deleterious expansions in concrete due to alkali-silica reaction.
  • Produces lighter color concrete due to its creamy white color.
  • Reduced efflorescence.
    Sikacrete® M-100 does not contain any calcium chloride nor any other intentionally added chloride containing ingredients.
ASR Controlling

ASR has been found to be responsible for the deterioration of various concrete structures including pavements, bridges, dams and other structures. The main reason for the occurrence of ASR is the presence of moderate to highly reactive aggregates and the utilization of high-alkali cements which are present in some regions. As a result, concrete for new construction in regions where ASR has been detected require the use of a mitigation alternative to help prevent ASR. Lithium nitrate admixtures are one of most effective mitigation options to prevent ASR.

Field evaluations should be carried out when concrete is to be placed in freezing conditions to determine the minimum ambient and concrete temperatures required, and the optimum dosage for the desired setting time and strength performance. Sika strongly recommends that appropriate sound curing practices be used to protect fresh concrete from excessive heat loss in extreme weather conditions.
Retarders

Sika Plastiment series extends the setting time of concrete allowing time for proper placement and finishing without cold joints.

Hydration Controlling Admixtures

Hydration controlling admixtures control the hydration rate of cement, rather than just delaying set time. In doing so, set times are significantly more predictable, dosing is more consistent, and concrete durability is unaffected. For applications ranging from underground tunneling and mining to managing the effects of long delivery times and heat, hydration controlling admixtures are a versatile solution to control concrete during its plastic state. SikaTard® Series of admixtures meets the requirements of ASTM C-494, Type B and Type D admixture.

Specialty Admixtures
Viscosity Modifiers & Underwater

Concrete placement characteristics are a function of the design and proportioning of cement paste, aggregates, and chemical admixtures. During scenarios such as pumping or placement underwater, the paste viscosity is an especially critical performance factor. The use of a viscosity modifying admixture (VMA) increases the cohesiveness of concrete, thereby reducing the risk of segregation.

Sika’s Viscoscity Modifying Admixtures meet relevant industry standards per application, such as ASTM C-494, Type S or CRD-C661-06. See product data sheets for details.

Surface Enhancement & Finishing

Sikament®-610 is designed for both the production of conventional slump concrete, as well as for SCC applications.    High Plasticity and Cohesion: The superplasticizing action of Sikament®-610 allows the production of high-slump concrete without segregation such that concrete can be placed with minimal vibrations even at low water cement ratios. Sikament®-610 is typically very cost effective when used for water reduction in the range of 20–25 %. Sikament®-610 maintains excellent cohesion within the concrete matrix eliminating excessive bleeding and/or segregation. The combined high range water reduction and efficient dispersing action of Sikament®-610 provide the following benefits in hardened concrete:   
  • Higher early compressive strengths for earlier removal of forms and structural use of concrete.
  • Higher ultimate strengths allow for greater engineering design flexibility and structural economies.
  • Reduced water cement ratios produce more durable, dense concrete with reduced permeability.
  • Highly effective dispersion reduces surface defects in concrete elements and improves aesthetic appearance.
  • In combination with set time accelerators or hardening accelerators, its fast setting characteristics and fast early strength development allows users to reduce the amount of heat necessary to achieve stripping strength.
    Sikament®-610 has been formulated to provide maximum water reduction and increased early strength. In addition improved finishing characteristics may be achieved, particularly when final finish, such as broom finish, is desired. Sikament®-610 does not contain calcium chloride or any other intentionally added chlorides and will not initiate or promote the corrosion of steel present in the concrete.
