PROSTRENGTH Rapid Set Concrete by Cement Australia is a high-performance, rapid-setting concrete mix proudly made in Australia. Engineered to deliver an impressive 40MPa strength—twice that of a standard rapid set mix—this product is perfect for demanding projects requiring superior durability and quick hardening. It is a TMR-approved product for bagged concrete (MRTS14), specifically suited for frangible support posts, ensuring reliability for professional applications.

PROSTRENGTH Rapid Set Concrete Applications

This versatile concrete mix is ideal for a range of projects, including:

• Professional fencing and gates
  
• Commercial signs and retaining walls
  
• Sporting equipment installations (e.g., goalposts, nets)
  
• General building site and home projects

PROSTRENGTH Rapid Set Concrete Key Features

• Rapid setting: Hardens quickly for faster project completion
  
• High strength: Achieves 40MPa, perfect for heavy-duty applications
  
• Made in Australia: Consistent quality from a trusted local manufacturer
  
• Pre-mixed convenience: Ready to use with just the addition of water
  
• TMR approved: Meets MRTS14 standards for frangible support posts

How to Use PROSTRENGTH Rapid Set Concrete

• Prepare the site: Dig a hole to the required depth and position the post.
  
• Pour the mix: Add the dry Prostrength Rapid Set Concrete around the post.
  
• Add water: Pour the recommended amount of clean water into the mix.
  
• Secure the post: Level and support the post until the concrete sets.
  
• Work quickly: Due to its rapid-setting nature, ensure all materials and tools are ready beforehand.
  

PROSTRENGTH Rapid Set Concrete Limitations

• Aluminum compatibility: Not suitable for use with aluminum posts or poles unless they are primed or sealed per the manufacturer’s guidelines.
  
• Temperature sensitivity: Avoid use in extreme conditions (below 10°C or above 35°C), as this can affect setting time.
  
• Mixing restrictions: Do not add extra cement, sand, aggregates, or admixtures. Avoid using concrete mixers or tools for mixing due to the fast hardening time.
  

Hints & Tips for Best Results

• Water usage: Use the minimum water necessary to maintain maximum strength—excess water weakens the mix.
  
• Preparation: Plan ahead and work swiftly, as this product sets rapidly.
  
• Pre-wetting: If the hole is dry, pre-wet it before pouring the mix.
  
• Temperature caution: Avoid direct sunlight in hot weather to prevent overly fast setting.
  
• Cleanup: Clean tools and equipment with water immediately after use to avoid concrete buildup.

Note: The 40MPa compressive strength and early strength development data were recorded under controlled laboratory conditions at 23°C. Actual strength may vary depending on factors like temperature, water content, and site conditions.
