V-MAR® admixtures
Rheology Modifying Admixtures for Concrete.
Easy to use for a wide variety of applications.
V-MAR® admixtures, improve concrete rheology to satisfy the needs of diverse applications. These include improving the segregation resistance of self-consolidating concrete (SCC), reduced washout during underwater concrete placements, zero slump extruded concrete and more. This product family aims to improve the ease and speed of forming and placing concrete.

- Product Name
- Description
- Key Benefits
- Applications Type
V-MAR® 10 P is a colloid based product giving the concrete a fattier, creamy consistency.
- Greatly reduced underwater washout
- Improved pumping qualities
- Reduced pumping pressures, and improved pumping distances
- Reduced segregation
V-MAR® 6R is an innovative low viscosity, highly efficient, rheology modifying admixture designed for the production of concrete with improved handling and processing characteristics. It enables pump mixes to be more easily and economically produced, as well as increasing tolerance to water variations or poorly graded aggregates. It is beneficial in improving cohesion of all concrete mix designs, including Self Compacting Concrete and can be used to reduce segregation, bleed and settlement of the mix constituents.
- Low viscosity, suitable for easy dosing
- Produces self compacting concrete which has excellent rheology
- Enhances the pumpability of concrete mixes, reducing pump pressures and increasing pumping distances
Thixotropic improvement for SCC
The first V-MAR® product, V-MAR® 3, was designed as a thickener, or viscosity modifier, to facilitate the production of self-consolidating concrete by increasing the moisture tolerance of the concrete. The thixotropic qualities of V-MAR® 3 helps prevent aggregates from segregating in the highly fluid concrete mixtures. V-MAR® 3 is recommended for use with ADVA® superplasticizers.
Underwater construction with minimal washout
In addition to use with self-consolidating concrete, V-MAR® 3 is also widely used for underwater concrete placement for applications including drilled shafts, bridge pilings, surge barriers and more. Underwater concrete construction is difficult due to that fact that cement fines may wash out, resulting in poor in-place concrete strength and harm to aquatic life. V-MAR® 3 will increase the cohesiveness of the concrete and allow it to consolidate underwater with minimal washout.
Improved productivity for zero-slump concrete producers
V-MAR® F100 is specifically designed for zero slump and low slump applications. This formulation of V-MAR® adds lubricity to concrete with low water content. This extra lubricity produces a better looking surface, while enhancing throughput and productivity. The concrete will move through machinery faster, without sticking and tearing the surface. V-MAR® F100 can also be used in conventional concrete to improve cast surfaces and reduce bugholes.
A better way to handle pervious concrete
Lastly, V-MAR® VSC500 is multi-functional admixture designed to treat pervious concrete, also known as no-fines concrete. This material is comprised of coarse aggregate and very little sand, producing a concrete with interconnected voids, which allow rainfall and runoff to drain into the underlying substrate. V-MAR® VSC500 ensures easier batching with less concern for loss of wet loads. At the construction site it permits faster truck discharge, provides enhanced robustness against ravelling and produces more uniform compaction, all of which lead to faster project completion. The properties that V-MAR® VCS500 impart to pervious concrete have also proved beneficial when used in roller compacted concrete (RCC), allowing contractors to easily overcome technical difficulties and handle these difficult concrete pavements with confidence.
