Chryso®V-Mar®
Rheology Modifiers
WORKABILITY | ENHANCED FINISHABILTY | DURABILITY
Chryso®V-Mar® Admixtures enhance concrete rheology for diverse applications, improving segregation resistance in self-consolidating concrete (SCC), reducing washout in underwater placements, and optimizing zero slump extruded concrete. These products streamline the forming and placing of concrete by improving workability and finishability with harsh aggregates and manufactured sands. By enhancing the lubricity and flowability of the concrete mix, they result in smoother placement and a higher-quality surface finish.
Chryso®V-Mar® 3: Thixotropic Improvement
Chryso®V-Mar® 3 is a thixotropic admixture that enhances the viscosity and stability of self-consolidating concrete (SCC). It improves moisture tolerance, prevents aggregate segregation, and enhances workability and surface appearance. With minimal impact on air entrainment and normal set times, it also helps reduce pump pressure, improves consistency in challenging conditions like high winds or low humidity, and mitigates both plastic and drying shrinkage cracks.
Chryso®V-Mar® F100: Improved Productivity
Chryso®V-Mar® F100 is a high-performance admixture developed for zero and low slump concrete, enhancing lubricity in low water content mixes to improve surface quality, productivity, and ease of placement. It modifies the concrete’s rheology to deliver cohesive, smooth-flowing mixes with improved workability that resists stickiness. This allows for efficient extrusion, faster discharge rates, and a consistently refined surface finish throughout the application.

Contractors often struggle to finish concrete, particularly in environments with high evaporation or when working with harsh aggregates or lower-carbon cementitious mixes like Type 1L cement. Conventional admixtures, such as evaporation retarding agents or silica-based additives, provide surface benefits but tend to lack in delivering internal consistency and long-term durability.
To address these challenges, Chryso® introduced a viscosity-modifying admixture (VMA) formulated with a proprietary blend of biopolymers. Unlike traditional admixtures that only work on the surface, this innovative VMA enhances the entire concrete matrix. The results were impressive: improved consistency of finish, reduced cracking, and enhanced production efficiency—all achieved without necessitating extensive adjustments to their operation. This comprehensive approach ensures improved internal consistency and durability, meeting the high standards of performance required in today’s construction industry.
By adopting Chryso®V-Mar® Admixtures, concrete producers are able to deliver a superior product, satisfying both contractors and clients. This breakthrough solution has set a new benchmark in concrete production, demonstrating that innovation and quality can go hand in hand.
“This product works through the whole mix, not just the surface.
That’s a game-changer.”

How the Chryso®V-Mar Series Works
Superior Finishability
Improves cream layer, concrete mix responsiveness, and reduces surface defects.
Pump & Place Efficiency
Lowers pump pressure and increases the ease handling coarse or low-slump mixes.
Weather
Resilience
Performs well in high evaporation environments such as in high-heat, windy, or with low humidity
Supports Sustainability
Works well with Type 1L cements, supplementary cementitious materials & harsh aggregates
The image shows how Chryso®V-Mar® 3’s unique polymeric structure aligns under energy—such as vibration or pumping—allowing coarse, angular sand to flow like rounded sand through the system. As the concrete moves, the polymers slide and reduce internal friction and pump pressure, then interlock again once the energy stops, returning the concrete to its original state.
