💡 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.

Pumped Concrete Application
💧
Controlled Water Content
🎯
Geoptimaliseerd Particle Grading
⚗️
Specialized Admixtures
📋

Key characteristics of a pumpable mix include:

01

Tightly controlled water content

just enough to prevent segregation or bleeding.

02

Optimized particle grading

fine materials form a smooth internal "lubrication layer."

03

Balanced cement‑sand ratio

provides uniform viscosity and steady pressure.

04

Specialized admixtures

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

LANDU Additives for Pumped Concrete

01

PCE Superplasticizer (PCE Flake)

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

Poederontstopper

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
03

Staalvezel

Strength That Travels

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