Sampelsæt inkluderer: ✓ 200 – 600 g valgte tilsætningsstoffer ✓ Detaljeret TDS og blandingsvejledninger ✓ Dosering anbefalinger fra vores F&U-team ✓ Global forsendelse inden for 5 – 7 arbejdsdage Request din gratis prøve i dag → Gratis prøve 200-600g sæt Ekspert svar FAQs – Pumpede beton tilsætningsstoffer Q1 Hvad gør beton pumpbart? Korrekt sortering af aggregater, lav vand-cement forhold, og brug af superplasticere og defoamers for at reducere friktion og segregation. Q2 Påvirker fibre pumpetrykket? ✓ Ikke ved LANDU doseringer. Stål- og PP-fibre forstærker matrixen uden at hindre flow, når det balanceres med PCE Flake. Q3 Hvor langt kan blandinger pumpes med LANDU tilsætningsstoffer? Over 100 m horisontalt og adskillige meter vertikalt, afhængigt af blandingsdesign og udstyrs kapacitet. Q4 Leverer LANDU teknisk support til pumpemix? Ja – komplet formeloptimering, fejlfinding på stedet og fjernkonsultation er tilgængeligt for partnere. Q5 Hvornår ankommer prøver? Vi sender globalt via FedEx / DHL inden for 5–7 arbejdsdage.

Smarter Flow. Stronger Concrete. More Efficient Construction.

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.

Controlled cURL Too many subrequests.

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

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

PCE Flake High Fluidity

Defoamer Clean Flow

Pulver Defoamere

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.

cURL Too many subrequests.

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

Stålfiber

Strength That Travels

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