"Let us help you build beautiful strong structures!"
Mix things up a bit!
Using admixtures can be a great, economical way to reinforce your concrete while improving the workability and performance of the concrete. Crown Hill Ready Mix carries only the highest quality admixtures from the most reputable and trusted manufacturers. Below is a list of some of the most commonly used admixtures in our industry, and we can get any type of admixture your spec calls for – just give us a call to discuss your special project.
About Our Admixtures
Features & Benefits
- Reduces initial set 1 to 4 hours depending on concrete temperatures
- Improves workability and provides denser concrete
- Minimizes bleeding and segregation
- Improves compressive strength development at early ages
- Decreases overtime allowing earlier finishing
- Increases protection for reinforcement in concrete
Applications
- Cold weather concreting
- Structural and plain concrete
- Precast and post tensioned concrete
EUCON WR 91 is a liquid, water-reducing and set retarding admixture for concrete. EUCON WR 91 shows improved setting and finishing characteristics when compared to other commonly used ASTM C 494 Type A water reducers. EUCON WR 91 may be used at a wide range of dosage rates. EUCON WR 91 does not contain calcium chloride or other potential corrosion enhancing ingredients.
Features & Benefits
- Improves finishability
- Improves workability
- Increases strengths at all ages
- Reduces permeability
- Increases durability
Applications
- Flatwork concrete
- General ready mixed concrete
- Architectural concrete
- Mass concrete
- Bridge decks
- Hot weather concrete
PLASTOL 6420 is a polycarboxylate based plasticizing admixture for concrete which is flexible enough to use as an ASTM C 494 Type A & Type F water reducer. PLASTOL 6420 is a mid-range/high-range water reducing and plasticizing admixture for concrete. PLASTOL 6420 shows improved finishing characteristics when compared to other commonly used Type A (typically 5-6% water reduction) or Type F (typically 12-15% water reduction) admixtures. This mid-range approach to water reducing admixtures allows for a wide range of usable dosage rates for a broad application spectrum. PLASTOL 6420 does not contain calcium chloride.
Features & Benefits
- Improves finishability
- Improves workability
- Increase early and late age strengths
- Reduces permeability
- Increase durability
Applications
- Ready mix concrete
- Precast concrete
- Cast in place
- Self-consolidating concrete
- Concrete mixtures utilizing Fly Ash, Slag or other natural pozzolans

EUCON AIR MAC 6 is formulated for use as an air entraining admixture for concrete of all types and is manufactured under rigid control which assures uniform and precise performance. EUCON AIR MAC 6 adds microscopic air bubbles in concrete and is acceptable to use in all types of concrete, including mixtures that have been traditionally difficult to entrain air. EUCON AIR MAC 6 does not contain added chlorides and will not promote the corrosion of steel.
Features & Benefits
- Provides a stable air void system with proper bubble size and spacing
- Improved air-void system protects concrete against damage caused by repetitive freeze/thaw cycles
- Concrete is made more resistant to de-icing salts, sulfate attack and corrosive water
- Reduces bleeding and segregation of concrete
- Less mixing water can be used per yard (meter) of concrete with improved placeability
Applications
- Ready mix concrete
- Structural concrete
- Mass concrete
- Paving concrete
- All exterior concrete subjected to freeze/thaw cycling
