Building the Foundations of Tomorrow with Science, Strength, and Precision
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.
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.
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 compressive and flexural strength without increasing cement usage
Reduced water demand and improved flow, even at very low water-cement ratios
Stronger early-age performance, vital for accelerated construction schedules
Enhanced durability against corrosion, wear, and environmental stress
Seamless integration with both precast and ready-mix production systems
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.
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.
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.
At LANDU, every additive is tested under controlled and real-world conditions to ensure consistent and verifiable results. Our R&D laboratories simulate performance across various cement types, aggregates, and curing environments, optimizing formulation for diverse geographical needs.
To validate performance before full-scale application, LANDU offers a free sample testing program. This allows engineers, project managers, and concrete producers to independently assess strength development and compatibility within their own mix design.
Our involvement doesn't end with supply—we become your technical partner. LANDU provides:
On-site or remote dosage optimization to achieve required compressive targets
Troubleshooting support for mix adjustments and stability issues
Custom-formulation development, tailored to unique cement compositions or regional requirements
Continuous performance tracking, ensuring consistency during production
By integrating LANDU into your material strategy, you're not just sourcing an additive—you're choosing a performance partner committed to long-term reliability, cost-efficiency, and environmental responsibility.
Depending on mix design and curing parameters, concrete using LANDU additives can reach compressive strengths beyond 80–100 MPa, with excellent durability and reduced shrinkage.
