Enhancing Pumped Concrete Performance through Advanced Fiber Reinforcement

Pumped concrete has transformed modern construction by enabling fast, efficient placement in high-rise buildings, tunnels, bridges, and infrastructure projects. Yet, pumping over long distances involves high pressure and shear that can affect cohesion and mechanical properties.

LANDU NovaStar™ Concrete Fibers deliver targeted reinforcement designed for fluid, high-performance systems. Using PP Macro Fiber, Chopped Steel Fiber, and Hooked-End Steel Fiber—NovaStar™ improves strength, durability, and pumpability without compromising flow.

Achieve seamless pumping operations, enhanced crack control, improved surface quality, and long-lasting structural performance—all from mix to placement.

The Need for Fiber Reinforcement in Pumped Concrete

Pumped concrete must maintain a delicate balance between flowability and internal cohesion. Traditional mixes with high slump and low viscosity are easy to pump but often result in segregation, bleeding, and reduced compressive strength. On the other hand, mixes that are too stiff can clog pipelines or cause inconsistent delivery.

Common Challenges in Pumped Concrete

Segregation and Bleeding
Coarse aggregates separating from mortar during long-distance pumping.
Plastic Shrinkage Cracks
Resulting from rapid moisture loss at exposed sections.
Reduced Strength Uniformity
Variations in compaction and settling during pumping.
High Wear and Tear
On pumping equipment due to inconsistent flow behavior.

Fiber Reinforcement Solution

Adding Concrete Fibers for Pumped Concrete addresses these issues directly. Fibers increase cohesion within the mix, reduce segregation, and improve structural stability, making the material more resistant to cracking and deformation during pumping, compaction, and service life.

Comparative Advantages Over Traditional Reinforcement

Fiber reinforcement has revolutionized the concrete industry—especially in pumped and flowable mixes—by replacing cumbersome and labor-intensive rebar or mesh systems. Unlike conventional reinforcement, which acts on defined planes, fibers provide volumetric, three-dimensional reinforcement.

Feature Fiber-Reinforced Pumped Concrete Traditional Reinforcement (Rebar/Mesh)
Distribution Uniformly dispersed throughout the mix Confined to specific layers or areas
Crack Control Controls micro and macro cracks Limited to separating cracks after formation
Installation No placement—fibers mixed at batch plant Manual installation required on-site
Labor Efficiency Quick, simplified batching Labor-intensive and time-consuming
Weight/Transport Lightweight for PP; reduced steel volume Heavy reinforcement handling required
Corrosion Risk None (PP) or low (treated steel) High risk over time
Pumpability High – compatible with pumping systems Mesh placement obstructs flow in formworks
