LANDU – The Global Specialist in High-Strength Concrete Additives

Building the Foundations of Tomorrow with Science, Strength, and Precision

💡 Innovation

Reimagining the Limits of Concrete Strength

📊

In modern construction, concrete strength is not merely a number—it defines how safe, reliable, and durable a structure will be over time.

As architects and engineers pursue taller, longer, and more complex designs, achieving high compressive strength with exceptional workability has become the key to performance-based construction.

Why Concrete Needs Additives for High Strength

Traditional concrete mixtures often face a challenge: increasing strength usually reduces workability and accelerates cracking. LANDU's advanced additives overcome this limitation by chemically and mechanically improving the mixture's internal structure.

🎯

By integrating our products into your concrete design, you can achieve:

💪

Higher Strength Performance

Higher compressive and flexural strength without increasing cement usage

💧

Optimized Workability

Reduced water demand and improved flow, even at very low water-cement ratios

⚡

Accelerated Development

Stronger early-age performance, vital for accelerated construction schedules

🛡️

Superior Durability

Enhanced durability against corrosion, wear, and environmental stress

⚙️

Seamless Integration

Seamless integration with both precast and ready-mix production systems

🏗️

Building the Future

With these properties, LANDU technology supports designers and contractors in constructing lighter, stronger, and more sustainable structures.

⚗️ Advanced Solutions

Core Additives for High-Strength Concrete

01

PCE Superplasticizer (PCE Flake Series)

Powerful Dispersion, Maximum Strength Retention

The PCE Superplasticizer from LANDU is a next-generation dispersant developed to deliver superior flow and compactness at minimal water content. Based on advanced polycarboxylate ether (PCE) polymers, this additive ensures precise compatibility with various cements and supplementary materials.

It significantly enhances slump retention, ensuring a smooth, uniform concrete mix ideal for high-strength, high-flow, and self-compacting concrete (SCC) applications.

💪

Technical Strengths and Benefits

  • Achieves water reduction rates up to 30–35%
  • Enhances early and ultimate compressive strength by improving particle packing
  • Ensures consistent slump flow over extended durations
  • Reduces porosity for denser, more durable structures
  • Completely soluble and dust-free for easy handling and accurate dosing
🏗️
Recommended Applications:

High-strength structural elements, precast components, high-rise foundations, bridge decks, post-tensioned beams, and ultra-thin wall panels.

High-Strength Reinforcement Fiber (Steel / PP Microfiber Series)

Microscopic Reinforcement, Macroscopic Strength

In addition to chemical enhancement, physical reinforcement is crucial in achieving superior ductility and crack resistance. LANDU's range of micro reinforcing fibers—including steel and high-modulus polypropylene—are specifically designed to fortify concrete from within.

They disperse evenly throughout the matrix, providing an internal network that resists cracking, enhances impact resistance, and distributes loading stresses.

💪

Technical Strengths and Benefits

  • Significantly increases flexural strength and post-crack toughness
  • Mitigates micro-crack formation during shrinkage and curing
  • Improves fatigue life and energy absorption capacity
  • Enhances structural integrity under dynamic and seismic loads
  • Maintains surface aesthetics and reduces maintenance costs
🏗️
Recommended Applications:

Heavy-duty industrial floors, bridge decks, airport pavements, tunnel linings, shotcrete, prestressed elements, and infrastructure exposed to cyclic loads.

CCCW – Crystalline Concrete Capillary Waterproofing Additive

Integral Protection and Strength Enhancement from Within

LANDU CCCW is an advanced crystalline additive formulated to provide both internal waterproofing and structural strengthening for high‑density, high‑strength concrete.

When mixed into fresh concrete, CCCW's active chemical components react with moisture and cement hydration by‑products to generate insoluble crystalline formations within the micro‑capillary network. These crystals block water passage, fill microscopic voids, and enhance the bonding structure of the cement matrix, resulting in concrete that is denser, stronger, and permanently self‑sealing.

💎

Unlike film‑forming surface coatings, CCCW protects the concrete mass from the inside out—making it ideal for projects where structural integrity and water resistance must coexist over decades of service life.

Technical Strengths and Benefits

  • Internal Waterproofing Reaction: Forms a permanent crystalline barrier throughout the matrix, eliminating permeability.
  • Higher Compressive Strength: Densifies the microstructure, improving both early and ultimate strength.
  • Self‑Healing Ability: Automatically seals hairline cracks up to 0.4 mm when exposed to moisture.
  • Extended Durability: Enhances resistance to chloride ions, sulfate attack, and chemical ingress.
  • Improved Bonding and Corrosion Protection: Protects embedded steel by reducing carbonation and moisture migration.
  • Synergistic Compatibility: Performs optimally when combined with LANDU PCE Superplasticizer, enabling high‑strength and watertight concrete simultaneously.
🏗️
Recommended Applications

High‑performance concrete structures in aggressive or moisture‑sensitive environments, including:

  • Underground and underwater foundations
  • Marine and coastal infrastructure
  • Water‑retaining structures such as basements, tunnels, and tanks
  • Precast high‑strength elements exposed to cyclic wet‑dry conditions
  • Long‑span bridge piers and decks requiring internal waterproofing and durability
