Proper grading of aggregates, low water‑cement ratio, and use of superplasticizers and defoamers to reduce friction and segregation. Q2 Do fibers affect pumping pressure? ✓ Not at LANDU dosages. Steel and PP fibers reinforce the matrix without impeding flow when balanced with PCE Flake. Q3 How far can mixes be pumped with LANDU additives? Over 100 m horizontally and dozens of meters vertically, depending on mix design and equipment capacity. Q4 Does LANDU provide technical support for pump mixes? Yes – complete formula optimization, on‑site troubleshooting, and remote consultation are available for partners. Q5 When will samples arrive? We ship globally via FedEx / DHL within 5–7 working days.

Technical Insight

Understanding Pumped Concrete

Pumped concrete is not an ordinary mix. It's a tailor‑made combination of cement, water, fine and coarse aggregates, and flow‑enhancing additives engineered to be transported by pump rather than manual vibration.

For concrete to move freely within hoses or pipelines, the system must remain cohesive yet fluid.

Optimized Particle Grading

Specialized Admixtures

Key characteristics of a pumpable mix include:

Tightly controlled water content

just enough to prevent segregation or bleeding.

Optimized particle grading

fine materials form a smooth internal "lubrication layer."

Balanced cement‑sand ratio

provides uniform viscosity and steady pressure.

Specialized admixtures

reduce friction, maintain cohesion, and keep the mix pumpable for hours.

LANDU Additives for Pumped Concrete

Superplastifikátor PCE (PCE vločka)

High Fluidity with Lower Water Demand

Our PCE Flake is the backbone of pumpable mixes. It disperses cement particles efficiently, allowing dramatic water reduction without sacrificing flow or strength.

Core benefits:

✓ Promotes self‑lubricating flow through pipes
✓ Prevents segregation and settlement
✓ Increases both early‑age and final strength
✓ Enables long‑distance pumping without clogging

PCE vločka High Fluidity

Defoamer Clean Flow

Práškový defoamer

Clean Flow, Compact Concrete

Air bubbles create flow instability and surface defects. LANDU Powder Defoamer releases entrapped air rapidly, producing a dense, even texture during pump delivery and final placement.

Advantages:

✓ Reduces back‑pressure caused by air pockets
✓ Eliminates pinholes and voids
✓ Enhances compressive strength and finish

Strength That Travels

When added to pumped concrete, Steel Fiber provides key reinforcement against cracking and impact fatigue without significantly affecting pumpability.
