Admixtures

ACCELERATOR: ACCELGUARD® NCA is an accelerating, water-reducing admixture for concrete that does not contain calcium chloride or added chloride ions. It improves properties of plastic and hardened concrete, provides a significant improvement in early stiffening and setting characteristics, improved workability and decreased bleeding and segregation. This admixture is compatible with air entraining admixtures, HRWR admixtures (super plasticizers), and conventional water reducing 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

AIR ENTRAINMENT: EUCON AEA-92 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. It should be added to the mix independently and not at the same time as other admixtures.
Features & Benefits
- Provides a stable air void system with proper bubble size and spacing
- Air void system protects concrete against damage caused by repeated freeze/thaw cycles
- Concrete is made more resistant to de-icing salts, sulfate attack and corrosive water
- Less mixing water can be used per yard (meter) of concrete and placeability is improved
- Helps control bleeding and segregation of the concrete
Applications
- Ready mix concrete
- Structural concrete
- Mass concrete
- Paving concrete
- All exterior concrete

SUPERPLASTICIZER: PLASTOL 6400 is a polycarboxylate based high range water-reducing admixture which enables concrete to be produced with very low water to cement ratios. PLASTOL 6400 produces flowable and self-consolidating concrete at low doses and can obtain up to 45% water reduction. PLASTOL 6400 does not contain added chlorides and will not promote corrosion in steel. PLASTOL 6400 is compatible with air-entraining agents, microsilica, accelerators and many other admixtures; however, each material should be added to the concrete separately.
Features & Benefits
- Produces low water content and low water/cement ratio concrete allowing higher strengths
- Produces flowing concrete with quicker stripping strengths
- Aids in concrete placement and reduces labor costs
- When used in precast work with Type I and Type III cements, PLASTOL 6400 will produce very high early strengths
- Improved air stability characteristics
Applications
- High performance concrete
- Negative slump concrete
- Heavily reinforced concrete
- Flatwork and mass concrete
- High early strength applications
- Precast/pre-stressed concrete
- High slump, flowable concrete

DELAYED SET: EUCON RETARDER 100 is a synthetically produced liquid water-reducing and set retarding admixture for concrete. It is a modified sodium gluconate. EUCON RETARDER 100 does not contain calcium chloride or other potential corroding materials and may be used in the presence of aluminum or zinc embedments. EUCON RETARDER 100 may be used at varying dosage rates to achieve extended set times compared to a control mix of up to 30 hours. Extended set times are frequently needed on bridge decks where the added dead weight of the concrete will cause deflection and a lack of bond to reinforcement and excessive cracking. It is compatible with air-entraining agents, waterproofers and calcium chloride.
Features & Benefits
- PLASTIC:
- Retards setting characteristics
- Improves finishability
- Improves workability
- Reduces water requirement
- Reduces segregation, keeping the mix cohesive
- HARDENED:
- Increases strengths
- Improves finished appearance
- Reduces cracking
- Reduces permeability
- Non staining
Applications
- Hot weather concrete placement
- Architectural concrete
- Concrete requiring water reduction and set time control
- Prestressed concrete
MID-RANGE WATER REDUCER: 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

MACRO FIBERS: TUF-STRAND SF “structural fibers” are a patented polypropylene / polyethylene synthetic macro-fiber successfully used to replace steel fibers, welded wire mesh and conventional reinforcing bars in a wide variety of applications.
TUF-STRAND SF fibers comply with ASTM C1116, Standard Specification for Fiber Reinforced Concrete and Shotcrete, and are specifically designed to provide equivalent tensile and bending resistance to conventional reinforcement requirements. Concrete reinforced with TUF-STRAND SF will have three-dimensional reinforcing with enhanced flexural toughness, impact and abrasion resistance and will also help mitigate the formation of plastic shrinkage cracking in concrete. Dosage rates will vary depending upon the reinforcing requirements and can range from 3.0 lbs/yd³ (1.8 kg/m³) to 20 lbs/yd³ (12 kg/m³). TUF-STRAND SF synthetic macro-fibers comply with applicable portions of the International Code Council (ICC) Acceptance Criteria AC32 for synthetic fibers, are UL certified for composite metal deck construction and are recognized within ACI 360 and SDI/ANSI-C1.0 as a reinforcing alternate to WWF.

Features & Benefits
- Equivalent strengths to WWM and rebar provided by engineering calculations. Controls and mitigates plastic-shrinkage cracking and reduces segregation and bleed water.
- Provides three-dimensional reinforcement against micro and macro-cracking
- Reduces equipment wear, fiber rebound and increases build-up thickness compared to steel fibers for shotcrete applications
- Increases overall durability, fatigue resistance and flexural toughness
