Trinic Stage II Blended Powder Hardener / Accelerator

Trinic Stage II is a specially formulated powdered admixture designed to boost early and ultimate strength in high-performance, thin-section concrete without reducing the initial working time. Traditional accelerators begin reacting immediately upon contact with cement, often shortening stage one and hindering placement. By contrast, Trinic Stage II aligns with the natural progression of concrete hardening—allowing for up to 1,000 psi per hour during stage two—while mitigating the effects of retarding agents like high plasticiser dosages. Compliant with ASTM C494 Type S requirements, this accelerator helps reduce curing times, maintain workability, and improve overall concrete quality.

Key Features & Benefits

1. Optimised Early Strength
   • Up to 1,000 psi per Hour: Rapid strength gains during the second stage of curing, improving turnaround times.
   • Maintains Initial Set: Delays onset of acceleration, preserving placement and finishing windows.
2. Enhanced Final Performance
   • Increased Ultimate Strength: Significantly boosts overall structural integrity.
   • Reduced Curing Times & Heat: Expedited project schedules, plus lower energy costs for heat-curing scenarios.
3. Synergistic Effects
   • Offset Retarders: Neutralises the slow set caused by high dosages of plasticisers.
   • Less Warpage & Cracking: Maintains dimensional stability in thin-section concrete, mitigating curling and early-age shrinkage.
4. Non-Corrosive Formula
   • No Calcium Chloride: Avoids promoting rebar corrosion, maintaining reinforced concrete durability.
   • ASTM C494-Compliant: Meets Type S “Specific Performance” criteria for chemical admixtures, ensuring proven reliability.
5. Flexible in Normal & Cool Conditions
   • High Next-Day Strength: Ideal for projects requiring rapid demould or fast turnaround.
   • Reduces Pozzolan Strength Lag: Speeds up strength development even with supplementary cementitious materials.

Recommended Applications

• High-Performance GFRC & Wet-Cast
• Thin-Section Concrete Elements
• Precast Concrete Products
• Commercial & Residential Projects where early strength is essential
• Projects in Cooler Climates needing reliable next-day strengths

Usage Guidelines

1. Dosage
   • Based on Project Needs: Typically introduced alongside plasticisers or other admixtures.
   • Follow Manufacturer’s Instructions: Usage rates depend on desired early strength gains and environmental conditions.
2. Mixing Procedure
   • Dry Blending: Ensure uniform dispersion by adding Stage II powder to the batch during the dry mix or at the start of the wet mix stage.
   • Combine with Plasticisers: Helps offset retarding effects, especially in high-dosage plasticiser scenarios.
3. Curing Recommendations
   • Reduced Curing Times: May enable faster demoulding and minimise or eliminate heat-curing requirements.
   • Optimal Performance: Maintain standard curing practices for final strength and surface quality.
