Rimix™ 3D Macro Synthetic Fiber for Faster, Stronger Slab Reinforcement
Challenges of Steel Fiber in Concrete Floors
Steel fiber is a well-established reinforcement method in steel fiber reinforced concrete, including commonly used types such as hooked-end steel fiber, crimped steel fiber, and glued steel fibers. It is widely applied in slab-on-grade construction, where it enhances crack resistance, post-crack load capacity, and overall toughness.

However, in practical applications, several challenges may arise:
1. Limited Fiber Dispersion and Workability
Steel fibers may not distribute uniformly during mixing, affecting consistency and overall performance.
2. Risk of Balling During Mixing
Fiber clustering can occur, leading to uneven reinforcement and construction difficulties.
3. Surface Exposure Affecting Finishing Quality
Exposed fibers may interfere with power-troweled finishes, impacting floor smoothness and appearance.
4. Pumping, Handling Effort, and Equipment Interaction
Higher dosage requirements increase material handling intensity, while steel fibers may affect pumpability and contribute to equipment wear.
5. Corrosion Risk and Cost Impact
As a steel-based material, it may introduce corrosion risks under certain conditions, and higher material consumption can increase overall project costs.
Rimix™ 3D macro synthetic fiber provides a more consistent reinforcement approach for concrete floors, improving constructability, surface quality, and long-term durability.
What Is Rimix™ 3D Macro Synthetic Fiber?
Rimix™ 3D is a high-performance macro synthetic fiber engineered for fiber reinforced concrete, industrial floors, slabs on grade, and shotcrete applications. As a structural-grade concrete reinforcing fiber, it is manufactured using premium PP-PE materials and functions as a reliable macro fiber reinforcement solution in demanding construction environments.
This synthetic macro fiber helps replace traditional welded wire mesh (WWM) as secondary reinforcement, delivering improved toughness, crack resistance, and long-term durability in macro fiber reinforced concrete.
Lightweight, non-corrosive, and easy to disperse, Rimix™ 3D macrofiber creates a dense three-dimensional distributed reinforcement network, enhancing performance across a wide range of concrete fiber applications.

How Rimix™ 3D Reinforces Concrete Floors
Rimix™ 3D is a structural reinforcement system for concrete floors that distributes high-performance macro synthetic fibers throughout the mix, forming a dense network of distributed secondary reinforcements across the entire slab.
By introducing a significantly higher number of reinforcement elements within the concrete matrix, this system improves crack control more effectively than conventional steel fiber reinforcement systems, including hooked-end and crimped steel fibers.
Engineered specifically for floor applications, Rimix™ 3D improves bond performance, pull-out resistance, and finishability. Its high tensile strength enhances post-crack residual strength, flexural toughness, and impact resistance, reducing cracking and extending the service life of concrete floors.

Why is Rimix™ 3D a better steel fiber alternative?
Rimix™ 3D is engineered for concrete floor applications, replacing welded wire reinforcement (WWR) and steel fiber systems with a dense distributed 3D reinforcement network that improves crack control in slabs-on-grade.
More Fibers. Better Crack Control.
Rimix™ 3D provides 5–10× more fibers than steel fibers, forming a dense reinforcement network that improves crack control and maintains post-crack strength.
Smooth Finish. Better Floor Quality.
Rimix™ 3D remains subsurface and does not interfere with power-troweled finishing, producing smooth and dense concrete floors.
No Wear. No Rust.
Rimix™ 3D disperses uniformly without fiber balling, pumps easily without blocking, and does not cause equipment wear. Unlike steel reinforcement, it also eliminates corrosion risks.
Lower Cost. Faster Construction.
Simplified installation reduces labor, accelerates construction schedules, and lowers total project costs.
This is why more engineers and contractors choose Rimix™ 3D when evaluating macro fiber vs steel fiber solutions.
No balling, NO rust; No exposure, Easy finish
