Concrete is the world's most widely used construction material, second only to water in total consumption. As infrastructure demands climb and sustainability standards tighten, the science behind cement chemistry continues to evolve. Among the innovations driving better performance, polycarboxylate ether (PCE) superplasticizers stand out as one of the most transformative.
Naphthalene sulfonates with limited performance
Advanced polycarboxylate ether technology
Next-generation sustainable solution
In modern ready‑mix concrete production, achieving high flowability, uniform dispersion, and long workability windows—without excessive water content—is crucial. Traditional plasticizers like naphthalene sulfonates are no longer sufficient for today's performance and environmental expectations. This is where LANDU's NOVASTAR™ 600F redefines what contractors and producers can expect from high‑range water reducers.
Formulated as a direct functional equivalent to Sika® ViscoCrete®‑5060, NOVASTAR™ 600F combines cutting‑edge PCE technology, extensive field testing, and sustainable manufacturing practices to deliver exceptional consistency, cost efficiency, and adaptability for ready‑mixed and precast applications worldwide.
Exceptional workability without excessive water content, maintaining structural integrity
Consistent particle distribution ensuring optimal concrete performance throughout
Long workability windows for complex projects and challenging conditions
Meeting modern environmental standards while delivering superior performance
NOVASTAR™ 600F is a polycarboxylate‑based high‑range water‑reducing admixture engineered specifically for modern concrete design. It offers both extended slump retention and high early‑age strength development, making it a smart choice for time‑critical structures and large‑scale transport operations.
Unlike traditional superplasticizers that rely solely on electrostatic repulsion, PCE superplasticizers—such as NOVASTAR™—operate through a combined mechanism of electrostatic and steric repulsion.
This ensures cement particles remain evenly dispersed, resulting in concrete mixes that are more workable, stronger, and more durable while using less water.
Versatile Applications
Ready‑Mix Concrete (RMC)
High‑Strength & Ultra‑High‑Performance Concrete
Self‑Compacting Concrete (SCC)
Pumped & Flowable Concrete
Concrete Modified with GGBS, Fly Ash, or Silica Fume
Precast Elements & Architectural Finishes
Whether used for infrastructure megaprojects, precast elements, or architectural concrete finishes, NOVASTAR™ 600F helps you achieve reproducible quality and efficient construction under diverse site conditions.
Advanced polycarboxylate ether chemistry for superior concrete performance
PCE molecules consist of a linear backbone that adsorbs onto the cement surface, and grafted side chains that project into the surrounding water phase. These side chains create a strong steric hindrance effect, preventing cement particles from flocculating.
The anionic groups on the PCE backbone impart a negative charge to cement particles, increasing repulsion forces that keep the suspension stable.
The side chains form a physical barrier around each particle, ensuring long‑term separation and extended workability.
Together, these interactions not only disperse cement particles efficiently but also reduce water demand by as much as 40%—achieving extraordinary rheology and performance over time.
Comprehensive performance advantages for modern concrete applications
Provides high water‑reduction efficiency and uniform cement dispersion.
Maintains workability for long delays—ideal for hot climates or distant transit.
Enhances early compressive strength and long‑term mechanical properties.
Performs reliably with supplementary cementitious materials like GGBS, fly ash, and microsilica.
Formulated for tropical and warm environments where slump loss is a major issue.
Delivers optimized performance even at reduced addition rates, improving cost control.
NOVASTAR™ 600F combines cutting-edge technology with practical benefits, delivering superior concrete performance across diverse applications and challenging conditions.
Versatile solutions for diverse concrete production scenarios
In ready‑mix operations, transportation time and temperature fluctuations can significantly affect slump retention. NOVASTAR™ 600F keeps mixes flowable through extended delivery windows, minimizing retempering and ensuring pumpability upon arrival at site.
Strength‑critical structures—such as high‑rise cores, bridges, or precast girders—require high early‑age gain without compromising durability. The superior dispersion of NOVASTAR™ allows lower water‑cement ratios while retaining outstanding compressive strength.
For SCC and highly flowable mixtures, achieving smooth flow without segregation is key. NOVASTAR™ 600F improves particle distribution, enabling defect‑free surfaces and reducing vibration or finishing effort.
Long pipeline pumping demands a stable mix and consistent rheology. NOVASTAR™ maintains viscosity and prevents blockage, allowing uninterrupted pumping across great distances or vertical heights.
Whether replacing cement with ground‑granulated blast‑furnace slag (GGBS), fly ash, or silica fume, NOVASTAR™ ensures homogeneous mixing and improved synergy between binders—contributing to stronger, greener, and more cost‑effective mixes.
In hot climates, water can evaporate too quickly, reducing slump and compromising uniformity. NOVASTAR™ 600F's extended retention properties safeguard concrete consistency even under extreme weather conditions.
From ready-mix operations to extreme weather conditions, NOVASTAR™ 600F PCE Superplasticizer delivers consistent, reliable performance that meets the demanding requirements of modern concrete construction.
Advanced molecular technology for superior concrete performance
Traditional superplasticizers, like naphthalene sulfonates or melamine formaldehyde resins, rely only on electrostatic dispersion, which provides short‑term fluidity but rapid slump loss. In contrast, third‑generation PCEs incorporate molecular side chains that extend retention many times longer.
Working Mechanism of PCE Technology
Higher water reduction (up to 40%) leading to denser microstructures
Slump retention up to 2 hours or more
Improved durability through lower porosity and permeability
Reduced segregation and bleeding
Formaldehyde‑free chemistry, meeting green building requirements
Thanks to these improvements, NOVASTAR™ 600F PCE Superplasticizer serves as a reliable Sika® ViscoCrete®‑5060 equivalent, providing consistent workability and mechanical performance in both ready‑mix and precast systems.

Maximizing concrete performance through advanced formulation strategies
By dispersing cement particles more effectively, NOVASTAR™ enables mixes to achieve the same slump at a much lower water‑cement ratio. Producers often observe up to 20% improved flowability compared to naphthalene‑based admixtures.
The lower water content yields a denser microstructure that accelerates hydration, resulting in higher early strength and continuous long‑term strength growth. This is particularly beneficial for precast plants and fast‑track infrastructure works.
Reduced porosity means greater resistance to carbonation, chloride ingress, and freeze–thaw cycles. Structures using NOVASTAR™ maintain their integrity even in aggressive environments like coastal areas or chemical plants.
Optimal dosage typically falls between 0.6 – 1.0% of cementitious materials by weight. However, LANDU's technical team assists customers in performing trial mixes to determine the perfect balance between rheology, setting time, and strength.
Optimized performance for challenging environmental conditions
High environmental temperatures can cause rapid slump loss and inconsistent strength gain. NOVASTAR™ 600F PCE Superplasticizer's molecular design slows water evaporation and maintains dispersion for significantly longer retention.
Typical field observations show:
Workability maintained for 60–120 minutes in 30°C–40°C conditions.
Minimal segregation even during long transport in agitated trucks.
Steady setting behavior enabling planned scheduling for multiple pours.
The result is smoother operations for ready‑mix suppliers servicing large job sites or remote locations.
The versatility of NOVASTAR™ 600F PCE Superplasticizer extends to high‑volume blended cements containing industrial by‑products.

While Sika® ViscoCrete®‑5060 is supplied as a liquid admixture, NOVASTAR™ 600F is uniquely designed and manufactured in flake (solid) form. The flake format introduces several practical and economic advantages without changing the underlying chemistry or performance characteristics.
NOVASTAR™ 600F PCE Superplasticizer flakes contain a much higher concentration of active polycarboxylate solids compared to liquid formulations that typically include 60–70% water. This means a smaller mass of flakes delivers the same effective dosage, drastically lowering freight, storage, and handling costs—especially for overseas shipments.
The flakes can easily be dissolved in water on‑site or in batching facilities to produce a ready‑to‑use liquid solution. Once reconstituted, the solution performs identically to conventional PCE liquids such as Sika® ViscoCrete®‑5060, ensuring seamless adoption for ready‑mix or precast operations.
Unlike liquid admixtures that may degrade or separate during long storage or under extreme temperatures, the flake version remains chemically stable for extended periods. It eliminates issues of microbial growth or viscosity changes, making it ideal for remote or hot‑climate projects.
By shipping a dry substance instead of a water‑heavy liquid, NOVASTAR™ 600F reduces transportation‑related carbon emissions and packaging waste. This aligns with LANDU's sustainability mission while allowing clients to prepare only the amounts they need—minimizing product losses.
Ready‑mix plants or distributors can tailor the solution concentration according to local water quality, mix design, or climatic conditions, granting flexibility that pre‑diluted liquids cannot provide.
While Sika®'s product offers ready‑to‑use convenience, LANDU NOVASTAR™ 600F flake form PCE Superplasticizer gives users unmatched efficiency, shelf stability, and sustainability, with identical concrete performance once dissolved. This makes it appealing for both bulk industrial blending and long‑distance export markets.
In modern concrete production, the margin between success and failure often lies in the choice of chemical admixture.
