Flowaid SCC – Self-Compacting Superplasticiser for GRC & Precast

Flowaid SCC is a high-performance polycarboxylate-based superplasticiser developed to enhance the workability, pumpability, and finish of premix GRC and precast concrete. Designed for self-compacting concrete applications, it delivers a smooth, flowable mix that reduces or eliminates the need for vibration—improving surface detail, reducing mould stress, and increasing productivity across all stages of manufacture.

By promoting high fluidity with minimal segregation and no retardation, Flowaid SCC ensures consistent strength and appearance in finished elements, even in complex or large-scale moulds. It’s ideal for manufacturers seeking reliable flow control and optimal surface finish without sacrificing strength or production speed.

Key Features & Benefits

Self-Compacting & High Flow
Effortless Mould Filling: Enables placement without vibration, perfect for intricate GRC shapes or detailed precast forms.
Segregation Control: Maintains homogeneity in high-fluidity mixes, even with extended working times.

High Strength & Water Reduction
Up to 40% Water Reduction: Improves density and early compressive strength while maintaining excellent workability.
Increased Performance: Produces stronger concrete at all ages with greater consistency across batches.

No Set Retardation
Fast Production Cycles: Slight set acceleration helps speed up demoulding and production turnaround.
Ideal for Spray-Up or Premix: Works across a wide range of casting methods without delays in curing.

Versatile Compatibility
All Portland Cements: Compatible with standard GRC and precast cement systems.
Multi-Use Functionality: Suitable for architectural elements, panels, moulded furniture, cladding, and more.

Efficient Mixing & Dosing
Easy Integration: Dose with mix water for rapid dispersion into the system.
Precision Control: Fine-tune flow and compaction by adjusting within the recommended dosage range.

Recommended Uses

Architectural Precast Elements: Supports detailed and complex formwork with excellent flow and finish.
Thin-Walled GRC Components: Reduces compaction requirements in delicate moulds or vertical forms.
Precast Cladding Panels: Improves casting speed and quality while reducing vibration damage.
Decorative Concrete Units: Enhances finish uniformity and mould fidelity in bespoke concrete work.

Mixing & Application Instructions

Dosage Guidelines
Use at 0.5% to 1.25% by weight of cement. Confirm exact dosage with trial batches based on cement content, mix design, and desired flow.

Dispensing
Add Flowaid SCC to the mix water before combining with dry materials. Ensure full dispersion for consistent performance.

Mixing Sequence

  1. Water & Admixture First: Combine water and Flowaid SCC in the mixing vessel.

  2. Add Dry Materials: Slowly introduce premix or cementitious materials while mixing.

  3. Check Flow: Adjust with superplasticiser if needed—avoid adding extra water.

  4. Final Fibres (if using): Add fibres last and mix gently to avoid clumping or over-shearing.

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.
