Retem System: Proven Strength Advantage

From Real-World Resilience to Lab-Verified Strength: The Retem System Strength Advantage

Not long ago we have published a post highlighting the exceptional performance of our Retem System in Mentone, Alabama. During intense rainfall that led to a complete road washout, our system remained intact, providing crucial structural guidance for the subsequent reconstruction. This real-world demonstration of durability prompted several questions about the underlying strength of our technology.

We're pleased to share the technical data that substantiates this field performance.

Quantifying Superior Flexural Strength: ASTM C78 Testing

To provide clear, comparative data on our system's strength, formal Modulus of Rupture testing (ASTM C78) was conducted on concrete beam specimens. This industry-standard test assesses flexural strength – a critical indicator of durability.

Testing Parameters:

  • Testing Authority: TTL, Inc. in Tuscaloosa, Alabama
  • Test Date: September 17, 2020 (for samples cast on August 20, 2020)
  • Specimen Size: 6 inches x 6 inches x 22 inches
  • Concrete Mix Design: 4000 psi Quikcrete
  • Condition: All specimens were tested at 28 days in a wet condition.
  • Fracture Location: Consistently in the middle for all tested beams, indicating valid test results.

Comparative Reinforcement Methods:

Three sets of specimens (three samples per set) were tested, each utilizing a different reinforcement method:

  1. Set 1: Retem System Reinforcement
  2. Set 2: Traditional Wire Mesh Reinforcement
  3. Set 3: Fiber Reinforced Concrete (FRC)

The Results Speak Volumes:

The average 28-day Modulus of Rupture results clearly demonstrate the superior performance of the Retem System:

  • Set 1 (Retem System): 526 psi
  • Set 2 (Wire Mesh): 466 psi
  • Set 3 (Fiber Reinforced): 465 psi

Key Takeaway:

These independent, standardized tests show that concrete reinforced with the Retem System achieved an average flexural strength approximately 13% higher than Wire Mesh and Fiber Reinforced Concrete under the specified conditions.

This quantifiable strength advantage, validated in the lab, directly correlates to the enhanced durability and resilience our customers witness in demanding real-world applications like the Mentone event. The Retem System isn't just strong in theory; it's proven in practice.
