Concrete is the foundation of modern construction — used in everything from skyscrapers and bridges to industrial floors and residential foundations. Yet, even this strong material has a weakness: it performs poorly under tension.
That's why reinforcement is essential. Traditionally, engineers have relied on steel rebar to give concrete the tensile strength it lacks. But now, fiber reinforcement, especially steel fiber and polypropylene (PP) fiber, is transforming how concrete is designed and built.
At LANDU, we provide advanced steel fiber and PP fiber technologies that enhance crack control, impact resistance, and long-term durability — delivering a smarter, more efficient alternative to traditional reinforcement.
Why Concrete Needs Reinforcement
Concrete is excellent in compression but weak in tension and flexure. Under shrinkage, temperature changes, or heavy loading, microcracks appear and can propagate into structural damage. Reinforcement helps concrete resist these tensile forces. Rebar, steel fiber, and PP fiber each improve performance — but in different ways. Understanding these differences allows engineers and contractors to select the optimal system for safety, cost, and efficiency.
What Is Fiber Reinforced Concrete (FRC)?
Fiber Reinforced Concrete (FRC) is a composite material containing small, evenly distributed fibers that improve tensile strength, control cracking, and enhance toughness.
LANDU Steel Fiber
For structural reinforcement and impact resistance
LANDU PP Fiber
For shrinkage control, surface durability, and chemical resistance
Together, they form a comprehensive reinforcement solution adaptable to both structural and non-structural concrete systems.
Fiber Reinforced Concrete vs Rebar: Key Differences
Understanding the fundamental differences between fiber reinforcement and traditional rebar helps engineers make informed decisions for optimal project outcomes.
| Особливість | Fiber Reinforced Concrete (FRC) | Rebar Reinforced Concrete |
|---|---|---|
| Reinforcement Form | Dispersed steel or PP fibers in mix | Steel bars embedded in concrete |
| Tensile Strength | Moderate to high (depends on fiber type) | Very high |
| Crack Resistance | Excellent micro- and macro-crack control | Limited to stress zones |
| Довговічність | Corrosion-resistant (especially PP fiber) | Vulnerable to rust |
| Construction Speed | Faster — mixed directly in concrete | Slower — requires layout and tying |
| Вартість | Lower labor and total cost | Higher labor and maintenance cost |
| Ideal For | Floors, tunnels, precast, pavements | Bridges, columns, structural beams |
LANDU Steel Fiber — Structural Strength and Toughness
LANDU Steel Fiber is engineered for high-performance structural concrete applications. Made from premium-grade steel, these fibers provide outstanding tensile and flexural reinforcement, improving crack resistance and load-bearing capacity.
High Structural Strength
Increases tensile and flexural strength of concrete, enabling superior load-bearing performance in demanding applications.
Superior Impact & Fatigue Resistance
Perfect for industrial floors, tunnels, and pavements where repeated loading and impact forces are common.
Uniform Stress Distribution
Dispersed reinforcement prevents large crack propagation by distributing stress evenly throughout the concrete matrix.
Reduced Rebar Dependence
In some applications, steel fiber can partially or fully replace rebar, simplifying construction and reducing costs.
Typical Applications:
Bridges, precast elements, industrial floors, airport runways, shotcrete, and tunnel linings.
When combined with LANDU's polycarboxylate superplasticizers, steel-fiber concrete achieves excellent workability and compaction without fiber clumping.
LANDU PP Fiber — Lightweight Crack Control and Durability
LANDU Polypropylene (PP) Fiber provides a non-corrosive, cost-effective reinforcement option ideal for crack control and durability enhancement.
Outstanding Crack Resistance
Prevents plastic shrinkage and temperature cracks by providing three-dimensional reinforcement throughout the concrete matrix.
Non-Corrosive & Chemically Stable
Ideal for humid or chemical environments where traditional steel reinforcement would deteriorate over time.
Easy Mixing & Application
No cutting or tying required, saving significant time and labor costs during construction.
Eco-Friendly Reinforcement
Reduces steel use and improves sustainability while maintaining excellent performance characteristics.
Застосування:
Residential floors, pavements, precast components, waterproof concrete, mortars, and decorative concrete.
When used with LANDU's RDP powders and HPMC, PP fiber improves adhesion, cohesion, and surface finish, ensuring long-term performance.
