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.

V-MAR® 10P is a colloid-based product giving the concrete a fattier, creamy consistency.
- Greatly reduces underwater washout with improved pumping qualities
- Reduces pumping pressures, improving pumping distances
- Offers reduced segregation
V-MAR® 3 is a high efficiency, liquid admixture designed to enable production of Self-Consolidating Concrete (SCC) by modifying the rheology of concrete.
- Self placement
- No segregation
- No blocking
- Allows for the production of SCC in applications where mix designs and materials can not be modified for SCC properties, such as exposed aggregate concrete
V-MAR® 4 is a high efficiency, liquid admixture designed to enable production of Self-Consolidating Concrete (SCC) by modifying the rheology of concrete.
- Self Placement
- No Segregation
- No Blocking
V-MAR® 5 is a high efficiency, liquid admixture designed to enable production of Self-Consolidating Concrete (SCC) by modifying the rheology of concrete.
- Self-placement
- No segregation
- No blocking
V-MAR® 6 is a rheology-modifying and mix-enhancing admixture that can be used in a variety of concrete mixes.
- Reduces friction within a concrete mix, making placing, screeding, pumping and finishing much easier
- Self-consolidating concrete SCC produced with V-MAR® 6
- Reduces or eliminates the amount of silica fume required
- Used with all types of Portland Cements and it is effective in concretes containing pulverised fly ash and/or ground granulated blast furnace slag
V-MAR® 7 is a high efficiency, liquid admixture designed to enable production of Self Consolidating Concrete (SCC) by modifying the rheology of concrete.
- Self-placement
- No segregation
- No blocking
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® 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® can also be used in conventional concrete to improve cast surfaces and reduce bugholes.
A better way to handle pervious concrete
Lastly, V-MAR® 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® 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® 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.
