UltraFiber 302

UltraFiber 302 in Cement

Product Description:

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.

Product Uses:

Commercial pavements, pervious pavements, bridge decks, steel decks, overlays & industrial slabs.

Mix Considerations & Addition:

UltraFiber 302 Blend requires mechanical mixing, generally accomplished by incorporating it into the mixer truck drum. UltraFiber 302 Blend generally does not require any special admixtures or additional water.


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


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


UltraFiber 302 Blend can be placed and finished using traditional tools, equipment and techniques. It is ideal for pumping, vibrating screeds, laser screeds, troweling equipment and hand tools.


UltraFiber 302 Blend is a secondary reinforcement that reduces plastic shrinkage, drying shrinkage, and crack retention. It will not replace structural or load bearing reinforcement. UltraFiber 302 Blend is not intended to be used in thin slab sections or to extend joint spacing past that which is recommended by ACI.
