LANDU – The Global Specialist in High-Strength Concrete Additives

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

Inovație

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.

LANDU High-Strength Concrete Additives

Scientifically engineered solutions that transform ordinary concrete into a high-performance material capable of meeting the strictest global standards. By enhancing hydration efficiency, optimizing internal bonding, and refining particle distribution, LANDU additives provide consistent results across projects of every scale—from high-rise towers and tunnels to industrial pavements and bridge decks.

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.

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

Durabilitate superioară

Enhanced durability against corrosion, wear, and environmental stress

Seamless Integration

Seamless integration with both precast and ready-mix production systems

Soluții Avansate

Core Additives for High-Strength Concrete

Superplasticizator PCE (Seria PCE Flake)

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

PCE Flake 30-35% Water Reduction

Fibra de Oțel

Fibre PP

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.

Absolutely. Our PCE superplasticizers and reactive agents are designed for seamless compatibility with typical SCMs.

Is there a difference between PCE Flake and liquid superplasticizers?

PCE Flake offers longer shelf life, lower transport volume, and easier handling while maintaining identical chemical performance once dissolved.

Can steel and PP fibers be combined in one mix?

Yes, hybrid fiber systems can be formulated for complex performance requirements, balancing strength, ductility, and crack resistance.

What is the typical dosage range for LANDU PCE Superplasticizer?

Recommended dosage varies between 0.15–0.35% by weight of cement, depending on strength targets and environmental conditions.
