R-E-D's Re-Act 4™SR – Slag Replacement

Re-Act 4™SR is a high-performance supplementary cementitious material manufactured from recycled glass and engineered as a sustainable alternative to traditional slag. Designed for a wide range of concrete applications, Re-Act 4™SR helps deliver excellent strength, durability, and long-term performance while reducing reliance on conventional cementitious materials.

Its lighter color can also contribute to a cleaner, brighter concrete finish, making Re-Act 4™SR an excellent option for ready-mix, precast, paving, marine, and high-performance concrete applications.

 

Key Benefits

Sustainable Slag Alternative
Manufactured using recycled glass, Re-Act 4™SR provides an alternative to traditional slag while helping support more sustainable concrete production.

High-Performance Pozzolanic Properties
Re-Act 4™SR contributes to the cementitious reaction within concrete, supporting strength development and long-term performance.

Improved Durability
Designed for demanding concrete applications where durability and resistance to aggressive environmental conditions are important.

Chloride Ion Resistance
Re-Act 4™SR can help produce concrete with improved resistance to chloride ion penetration, making it well suited for marine environments, bridge structures, parking structures, and other applications exposed to deicing salts or saltwater.

Sulfate & Corrosion Resistance
Its performance characteristics make Re-Act 4™SR an excellent option for concrete systems requiring additional resistance to sulfate exposure and reinforcing-steel corrosion.

High Compressive Strength
Re-Act 4™SR can be incorporated into mix designs requiring strong long-term compressive performance.

Lighter Concrete Finish
Compared with many traditional supplementary cementitious materials, Re-Act 4™SR can produce a lighter and cleaner-looking finished concrete surface.
