Understanding Ronafix SBR The Versatile Admixture

In the world of construction and building materials, the choice of admixturescan significantly influence the performance and longevity of concrete structures. One such versatile and time-tested solution is Ronafix SBR, a Styrene-Butadiene Rubber admixture that has been redefining high performance screeds and mortars since the early 1970s. This article delves into the features, benefits, and applications of Ronafix SBR, highlighting why it remains a preferred choice for construction professionals globally.

Ronafix SBR admixture is specifically designed to enhance the performance of renders, screeds, and mortars. Its unique combination of properties allows it to be effectively utilised for diverse applications such as repair, bonding, tanking, and flooring.

Key Properties

Enhanced Physical Properties:

Ronafix SBR significantly improves the physical characteristics of mortars and screeds, resulting in materials that are not only durable but also resilient under various conditions.

Abrasion Resistance:

One of Ronafix SBR’s standout features is its excellent abrasion resistance (up to AR0.5), which makes it ideal for high-traffic areas and ensures longevity in demanding environments.

Versatility:

Suitable for both internal and external use, Ronafix SBR is adaptable to a range of applications, from unbonded and floating screeds to bonded screeds.

Rapid Setting Times
For flooring involving foot traffic , Ronafix SBR screeds can be accessed the next day, while heavy traffi c can resume after 3-5 days, depending on the thickness and application.

Applications

Ronafix SBR is versatile and can be used in various conditions:

Bonded Screeds : Minimum application thickness of 10mm is recommended
Unbonded & Floating Screeds A minimum thickness of 35mm is required for optimal performance.
Polymer Screeds Underfloor heating systems can be effectively intergrated with Ronafix SBR formulations, making it a versatile choice for modern building requirements.

Technical Highlights

Solid content: Ronafix SBR boasts the highest solid content in the industry of 47%, enhancing it's performance.
Compressive and Tensile Strength: Depending on the application, the product achieves compressive strengths up to 70N/MM and tensile strength of 7N/MM.
Track record: With over 50 years in use, Ronafix SBR has garnered a robust pedigree, making it a trusted solution in prominent landmarks and constructions around the world, including the House of Lords and Wembley Stadium.

Application Guidelines

Surface preparation: Ensure the surface is laitance free, textured, clean and free from loose materials.
