MACt Admix

MACt Admix  is Australia’s leading powdered additive for Glass Fibre Reinforced Concrete (GFRC), engineered to elevate your concrete formulations across multiple performance areas. This multi-component powder functions as a water-reducing agent, cure modifier, defoamer, anti-shrinkage solution, and ultra-performance booster—ensuring GFRC mixes that are stronger, more durable, and easier to work with. Its versatile formula also helps minimise crazing, curling, and air entrapment, creating a smoother, more consistent finish ideal for both decorative and high-demand applications.

Key Features & Benefits

1. Water-Reducing Agent
   • Lower Water Content: Reduces the water-to-cement ratio, leading to higher compressive and flexural strength.
   • Enhanced Workability: Yields a more flowable mix, saving labour and simplifying intricate or large-scale pours.
2. Cure Modifier & Defoamer
   • Optimised Curing: Improves the rate and consistency of the curing process for a stronger, longer-lasting product.
   • Reduced Air Bubbles: Eliminates unwanted voids that can compromise surface integrity and appearance.
3. Anti-Shrinkage Technology
   • Less Cracking: Slows moisture loss, minimising contraction-related stresses.
   • Stabilised Final Product: Lowers the risk of future cracking or warping, even in challenging conditions.
4. Ultra-Performance & Strength
   • High Compressive & Flexural Gains: Fortifies GFRC to withstand heavy loads, impacts, and repeated stress cycles.
   • Improved Surface Finish: Supports the creation of smooth, aesthetically pleasing forms without sacrificing durability.
5. Mixing Aid
   • Reduced Crazing & Curling: Achieves uniform internal structure, ensuring consistent finishing results across all project scales.
   • Compatible with MACt Plasticiser: Maximises water-reduction potential and overall concrete performance.

Recommended Dosage & Usage

• Dosage Rate: Typically 3% of the total cementitious content at a 0.28 water percentage.
• Pair with MACt Plasticiser: Further boosts flowability, strength, and overall concrete quality.

Example Dosage

• 3% of cementitious content, plus recommended MACt Plasticiser to suit specific project needs.

Versatile Industry Applications

• GFRC: Thin-walled cladding, architectural panels, and decorative features.
• Precast Concrete: Beams, columns, panels—improves strength, durability, and surface quality.
• Decorative Concrete: Countertops, flooring, stamped surfaces—achieves vibrant colours, textures, and finishes.
• Shotcrete: Sprayed applications (e.g., tunnel linings, pools, retaining walls) for enhanced bond strength and workability.
• Self-Consolidating Concrete (SCC): Improves flow, strength, and durability without vibration.
• High-Strength Concrete: Ideal for demanding infrastructure like high-rise buildings, bridges, or heavy-load foundations.
• Pervious Concrete: Ensures effective water permeability while maintaining robustness and longevity.

How MACt Admix Works

1. Water Reduction
   • Lowers water demand, boosting compressive/flexural strength and lowering shrinkage potential.
2. Improved Curing
   • Adjusts the hydration process for more consistent setting and final strength gain.
3. Defect Control
   • Defoaming and anti-shrinkage measures minimise entrapped air, cracks, and surface inconsistencies.
4. Extended Durability
   • Creates dense, long-lived concrete capable of resisting weathering, chemical exposure, and mechanical stresses.

Storage & Handling

• Packaging: 1–10 kg units, sealed to maintain powder integrity.
• Environment: Store in a cool, dry location, tightly sealed to prevent moisture exposure.
• Safety: Use appropriate PPE (e.g., gloves, dust mask) to avoid inhaling powder; consult SDS for details.
