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.
just enough to prevent segregation or bleeding.
fine materials form a smooth internal "lubrication layer."
provides uniform viscosity and steady pressure.
reduce friction, maintain cohesion, and keep the mix pumpable for hours.
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.
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.
Strength That Travels
When added to pumped concrete, Steel Fiber provides key reinforcement against cracking and impact fatigue without significantly affecting pumpability.
