ADVA® high-range water reducers
High-range water reducers used to consistently produce high strength concrete
ADVA® is a family of high-range water reducers used in the production of ready mix, precast and prestressed concrete. In addition to providing excellent water reduction, ADVA® products generate higher compressive strengths, better slump retention, improved rheology, enhanced air control, superior finishability and robustness across a wide range of materials, including both flowable and self-consolidating concrete.

ADVA® 841U is a liquid, high range, polycarboxylate ether-based (PCE) admixture designed to work effectively in concrete mixes with both low and high binder contents.
- Delivers very high ultimate and early strengths and an improved surface finish with reduced stickiness
- Good flow through congested reinforcement without stickiness and low thixotrophy, thereby reducing noise and labour cost from vibration
- Enables concrete to retain workability for longer time without seriously affecting setting time, as it delivers very high water reduction at controlled set retardation
- Concrete grades up to 50 MPa, where controlling setting times using conventional admixtures proves difficult
- Fair-faced concrete with high flow and early strength for early stripping of formwork
- Concrete that requires transport or pumping over long distances
ADVA 845 is a liquid mid range Polycarboxylate ether based admixture essentially designed to work in concrete mixes with medium to high binder contents.
- Can replace conventional naphthalene admixtures used in ready mix concrete
- Has a good dosage range to work over different types of mixes to offer desired performance
- Retains slumps for longer times with minimal retardation in contrast to conventional naphthalene admixtures
ADVA 960U is a High Performance liquid PCE based admixture to cover several applications.
- No Chlorides: No chlorides / salts are added in ADVA 960U
- Strength: ADVA 960U offers excellent strength in comparison to many other equivalents in the market
- Applications: Works across many concrete mixes offering flexibility on water reduction and slump retention
ADVA® 976 is a liquid, mid-range, polycarboxylic ether-based (PCE) admixture that produces concrete with workability retention up to three hours
- Offers high water reduction and excellent slump retention
- Delivers very high ultimate and early strengths and an improved surface finish with reduced stickiness
- Good flow through congested reinforcement without stickiness and low thixotrophy
- Concrete grades up to 50/60 MPa needing long distance travel, perhaps due to traffic conditions
- Projects where workability loss is anticipated, maybe due to pumping at higher altitudes
- Where workability retention over a longer time period is critical
ADVA® products do it all
Whether it’s keeping the water/cement ratio to a minimum while achieving high strength and durability or producing extremely workable high slump, there's not a lot that ADVA® products can't do.
ADVA® 405 when used in Self-Consolidating Concrete (SCC) provides excellent blemish-free form finishes. ADVA® 198 provides excellent slump retention and near neutral set properties. From design to production to construction, there's no aspect of the concrete creation process that ADVA® can't help with.
What are the benefits of Self-Consolidating Concrete?
Self-Consolidating Concrete is a highly flowable, non-segregating concrete that spreads into place, fills formwork, self-compacts and encapsulates even the most congested reinforcement, all without any mechanical vibration.
SCC produced with ADVA® products provides unique advantages over conventional flowing concrete:
-
Lower SCC viscosity
-
Self placement
-
No segregation
- No blocking
Workability, durability, high strength result in superior concrete
ADVA® products are high efficiency polycarboxylate-based superplasticisers especially formulated to extend slump-flow life while imparting extreme workability without segregation to concrete, to achieve high early compressive strength.
These ADVA® products can:
-
Produce SCC concrete with extremely high levels of workability without segregation.
-
Provide superior water tolerance to the concrete making it less susceptible to normal manufacturing moisture fluctuations.
-
Extend slump life to enable batch plant adjustments and predictable job site plastic properties.
-
Provide superior concrete surface finish characteristics with reduced bugholing.
