MACt Plasticiser is a premium additive formulated to enhance the workability, plasticity, and performance of Glass Fibre Reinforced Concrete (GFRC) and other high-performance concrete mixes. Acting as both a water-reducing agent and a defoaming solution, MACt Plasticiser improves flowability, surface finish, and strength, making it a versatile essential in the production of high-quality concrete elements. Whether you’re constructing high-rise structures or crafting detailed precast products, MACt Plasticiser delivers reliable, professional results.

Key Features & Benefits

  1. Enhanced Workability & Flow
    • Improved Pourability: Helps GFRC flow smoothly around corners and through complex formwork, reducing labour costs and project timelines.
    • Better Surface Finish: Produces a more uniform, blemish-free surface in GFRC and other concrete applications.
  2. Water Reduction & Strength
    • High-Range Super Plasticiser: Lowers water content while increasing compressive and flexural strength.
    • Reduced Shrinkage & Cracking: Achieves denser, more durable concrete with fewer structural weaknesses.
  3. Defoaming Properties
    • Air Bubble Elimination: Removes unwanted air pockets that can lead to voids and inconsistencies in the finished product.
    • Smooth Consistency: Yields a cleaner, more seamless appearance without compromising mechanical performance.
  4. Versatile Application
    • Self-Compacting Concrete: Maintains workability for SCC, especially useful in demanding or large-scale projects.
    • Colour Dispersion: Ensures even pigment distribution, critical for decorative or specialised colour-matching requirements.
  5. Wide Industry Use
    • GFRC, Precast, Shotcrete: Suitable for everything from thin-walled panels to robust infrastructure elements.
    • Ideal for Challenging Conditions: Effective for high-rise, tunnels, bridges, and other scenarios requiring superior flow and finish.

Recommended Dosage

  • Standard Dosage: 0.4% of the total cementitious content.
  • GFRC Spray Coat: 20–30 g per 20 kg premix.
  • Backing Coat: 30–50 g per 20 kg premix.
  • SCC Mix: 50–70 g per 20 kg premix.
Note: Dosage may be adjusted based on project requirements and mix designs. Always test small batches for optimal results.

Handling & Storage

  1. Dust Precautions
    • Avoid Dust Formation: Can form an explosive mix with air if proper ventilation is not provided.
    • Prevent Electrostatic Discharge: Ensure grounding and take measures against static build-up.
  2. Safety Measures
    • Risk of Slipping: Substance can become slippery when wet.
    • Keep Away from Ignition Sources: Maintain distance from open flames, sparks, or excessive heat.
  3. Storage Recommendations
    • Hygroscopic: Tightly seal containers; store in a cool, dry, and well-ventilated area.
    • Shelf Life: Preserved by avoiding direct contact with moisture or extreme temperatures.

Why Choose MACt Plasticiser?

Got any question?

Browse through our frequently asked questions to find answers on everything from mould preparation and casting techniques to finishing and long-term maintenance.

Australia’s warm and, in many regions, coastal climate necessitates adjustments during manufacturing. High temperatures can accelerate hydration, so controlled curing environments—such as covering pieces with plastic to retain moisture—are essential. Additionally, lower water-to-cement ratios and carefully selected admixtures help mitigate rapid evaporation and ensure that GFRC develops its designed strength and durability.

Manufacturers address these challenges by:

  • Using precision mixing equipment to achieve a uniform blend and ensure proper fibre distribution.
  • Fine-tuning spray parameters (such as pressure, nozzle design and technique) to avoid voids, pinholes and surface defects.
  • Regular maintenance of equipment and continuous operator training.
  • Adjusting admixture dosages as required to optimise workability and adhesion.

Future trends include increased automation—such as robotic spraying and digital mould design—as well as a greater focus on sustainable practices (e.g. incorporating recycled materials and eco-friendly admixtures). Advances in fibre treatment technology and computer-aided manufacturing are enabling more complex, custom-designed panels. Ongoing research is continually refining mix designs and curing methods to better suit Australia’s diverse environmental conditions.

GFRC is a composite product that combines high‐quality cement, fine aggregates, polymers and alkali‐resistant glass fibres – all premixed to the correct proportions. Its high strength‐to‐weight ratio, durability and capacity for being cast in thin, custom shapes make it ideal for creating stylish and long-lasting benches and tables for both indoor and outdoor use.

GFRC manufacturers must comply with Australian building codes and standards relating to precast concrete, structural performance and safety. This means that production processes, material testing and installation methods are stringently monitored and documented. Close collaboration with local certifying bodies ensures that GFRC products meet all necessary performance and regulatory requirements.

With our premix product, all the ingredients are already proportioned for optimal strength and workability. This means you can focus on preparing your moulds and executing a neat cast rather than measuring raw materials.

Moulds for benches and tables can be constructed from high-density foam, melamine, or even silicone for more intricate designs. It is essential that the mould is smooth, watertight and well supported. Pre-treat the interior with a quality release agent to ensure that the cured GFRC can be removed cleanly.
