Re-Act 4™ by R-E-D Industrial Products

A Sustainable, High-Performance SCM Alternative

Re-Act 4™ delivers a premium advantage in both function and sustainability, offering a reliable solution for extending the longevity and improving the viability of concrete applications. Below is a breakdown of how Re-Act 4™ supports sustainable practices while delivering superior performance.

Sustainability Benefits

Re-Act 4™ serves as an effective replacement for traditional supplementary cementitious materials (SCMs) that are becoming increasingly scarce, such as:

  • Fly Ash

  • Slag

  • Silica Fume

Additionally, it offers a sustainable alternative to conventional Portland cement, which is a significant source of CO₂ emissions.

Performance and Environmental Benefits Include:

  • Increased concrete strength and long-term durability

  • Reduced linear shrinkage

  • Minimized efflorescence

  • Superior compressive strength

  • High chloride ion resistivity

Ideal Applications

Re-Act 4™ is suitable for a wide range of projects, especially those requiring a green SCM alternative that meets ASTM standards. Its robust performance profile makes it ideal for:

  • Harsh Environments:
    With high resistance to sulfate attack and natural corrosive elements, Re-Act 4™ is ideal for projects exposed to chemical and environmental stressors.

  • High-Impact Infrastructure:
    Its compressive strength and durability make it ideal for use in demanding infrastructure applications—reducing lifecycle costs.

  • Marine & Submerged Structures:
    Outstanding chloride ion resistivity makes Re-Act 4™ a smart choice for marine concrete structures such as bridges, piers, and underwater tunnels.

  • Cold Weather Regions:
    Exceptional resistance to freeze-thaw cycles ensures concrete longevity even in extreme climates.

Why Choose Re-Act4

    • Addressing SCM Scarcity:
      As coal plants close and fly ash supplies dwindle, Re-Act 4™ provides a consistent, scalable alternative.

    • 100% Recycled Material:
      Made entirely from recycled inputs, Re-Act 4™ significantly reduces greenhouse gas emissions associated with cement production.

    • Promotes Circular Economy:
      Diverts material waste from landfills and repurposes it for high-value environmental applications.

    • Abundant Supply:
      With availability in the millions of tons, Re-Act 4™ helps stabilize SCM supply chains and support growing infrastructure demands.

    • Cost-Effective:
      Helps reduce the cost of traditional concrete production while enhancing sustainability metrics.
