LANDU – Additives for Pumped Concrete
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.
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
PCE-superplastifikaattori (PCE-helmi)
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
Jauhevaahtoestovaahdottaja
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
