UltraFiber 302 Blend - Cellulose & Steel Fiber Secondary Reinforcement

Advantages of UltraFiber 302 Fiber Blend: ACI 302 recognizes the benefits of using a natural cellulose micro fiber and steel fiber blend to reduce early age plastic shrinkage and provide long term crack control. Additionally, this fiber blend improves the tensile strength/capacity of the concrete. The UltraFiber 302 Blend can replace traditional continuous steel for temperature and shrinkage reinforcement. UltraFiber 500® is the fiber of choice for decorative concrete and a proven performer reducing plastic drying shrinkage in residential, light commercial, overlays and structurally reinforced concrete. CFS 150-5 steel fibers have long been a solution for longer term concrete crack control and added tensile capacity in the same applications. Combining these two fibers creates “peace of mind” in overlays and traditional 4” to 6” building slabs and pavement designs within ACI joint guidelines.

Information for Architects

ACI 302-15 will be adopted by the building codes. New requirements of ACI 302-15 will include: all concrete building slab on grade construction to be placed on a vapor barrier, 4x4 – 4.0 – 4.0 properly supported welded wire fabric or steel fiber / micro fiber blends. UltraFiber 302 Blend is a cost effective alternative to WWF and light rebar installations.

Product Use

Sidewalks, drives, pavements, pervious, overlays and industrial slabs. Ideal for colored concrete, stamping and textures. Mix Considerations and Addition: The UltraFiber 302 Blend requires mechanical mixing generally accomplished by incorporating into the mixer truck drum. UltraFiber 302 Blend generally does not require any special admixtures or additional water. UltraFiber 302 Blend comes in degradable bags that can be added prior to, during or after the batching of the concrete. Mixing time is suggested to be at least 5 minutes at a mixing speed as specified in ASTM C 94. Personnel handing the bags should wear gloves and eye protection.

Compatibility: UltraFiber 302 Blend is compatible with all commonly used concrete admixtures and traditional mix designs. No additional admixtures are required for workability.

Dosage: The standard dosage of the UltraFiber 302 Blend is one 16.5 lbs. (7.48 kg) bag per cubic yard of concrete.

Finishing: UltraFiber 302 Blend can be placed and finished using traditional tools, equipment and techniques. Ideal with pumping, vibrating screeds, laser screeds, troweling equipment and hand tools.


UltraFiber 302 Blend is considered a secondary reinforcement to reduce temperature and plastic shrinkage, reduction of drying shrinkage and crack retention. Will not replace structural or load bearing reinforcement. UltraFiber 302 Blend is not intended to be used to thin slab sections or extend joint spacing past that which is recommended by ACI industry standards.


UltraFiber 302 Blend is available in 16.5 lbs. (7.48 kg) water soluble – degradable bags. The UltraFiber 302 Blend bags are palletized and shrink-wrapped for protection in shipping.
