What Is Grouting Mortar and Why It Matters

Grouting mortar is a high‑flow cement‑based material that fills voids and anchoring gaps with precision. It is used to:

▸
Level and secure machinery foundations
▸
Anchor steel reinforcements and bolts
▸
Install bridge bearings and rails
▸
Repair cracks and voids in concrete
▸
Fill ducts for pipelines and cables
▸
Provide non‑shrink support beneath structural components

Aditivi pentru performanță

Pentru a menține aceste amestecuri stabile și pompatabile, formulele moderne se bazează pe aditivi de performanță care îmbunătățesc reologia, limitează sedimentarea și mențin rezistența la legare încă din prima zi.

⚙️ Technical Excellence

How LANDU Additives Improve Grouting Performance

01
💧

Eter Celulozic (HPMC / HEMC)

Pentru flux coerent și lucrabilitate optimizată

Acts as a water‑retaining and rheology‑control agent to stabilize mixes and maintain lubrication through the pump line.

Technical advantages:

  • • Consistent hydration and stable flow through formwork
  • • Prevents segregation and bleeding even at low W/C ratios
  • • Extends open time for precision placement
  • • Improves surface finish and anti‑shrink behavior
02
🛡️

Pulbere de polimer redispersibil (RDP)

Pentru aderență, flexibilitate și integritatea legăturii pe termen lung

RDP modifies the cement matrix to improve bond to concrete and steel while adding ductility for crack resistance.

Technical advantages:

  • • Higher adhesion to substrates and reinforcement
  • • Better tensile and bending resistance under load
  • • Improved freeze‑thaw durability and fatigue strength
  • • Enhanced structural flexibility to prevent micro‑cracks
🔬

Performanță sinergică

Used together, HPMC + RDP create a grout that is fluid enough for perfect filling and strong enough to carry heavy loads without shrink or segregation.

❓ Răspunsuri de la experți

Întrebări frecvente

Q1

Can LANDU customize grouting additives for my raw materials?

💡

Absolutely. We adjust HPMC viscosity and RDP flexibility based on your aggregate and cement types, offering full compatibility testing and formula tuning.

Q2

What is the typical HPMC dosage in grouting mortar?

⚖️

Normally 0.2 – 0.5 % by cement weight; exact level depends on desired flow and environmental conditions.

Q3

Which grades should I use for different temperature zones?

🌡️

Use HPMC K100/K200 for moderate conditions and HEMC EM series for hot climates (> 35 °C) to maintain viscosity and open time.

Q4

Which RDP should I consider for my grout?

🔬

Alege RDP 4025N for semi‑flexible performance and RDP 5011N for rigid, high‑strength grouts; 8035H hydrophobic grade is recommended for humid or submersed conditions.

Q5

Can HPMC and RDP be used together?

✓

Yes – the combination offers synergy: stable flow, higher adhesion, better crack control, and improved durability. LANDU provides the right ratio guidance.

Q6

How to prevent bleeding and segregation in grout mixes?

🛡️

Optimize HPMC dosage, use RDP 4025N, add micro PP fibers for reinforcement, adjust aggregate gradation, and reduce water content with a PCE superplasticizer.

Q7

How do LANDU additives improve pumpability for vertical grouting?

⬆️

They create uniform viscosity and self‑lubrication within pipes, reducing friction and pressure drops for consistently smooth delivery even at 30–50 m heights.
