Overview

Randomized trial develops corrosion-resistant concrete in Iraq, suggesting improved durability for underwater structures.

Key Points

  • The study aims to create a high-strength, corrosion-resistant concrete using local Iraqi materials to enhance durability in aggressive environments.
  • Developed corrosion-resistant heavy concrete using a multi-component binder with local raw materials.
  • Evaluated concrete mixtures based on compressive strength, axial tensile strength, flexural strength, and mass loss after three months exposure to aggressive environments.
  • Incorporated metakaolin and fly ash to replace Portland cement, enhancing strength and durability.
  • Concrete with metakaolin and activated fly ash showed superior density, strength, and corrosion resistance compared to conventional concrete.
  • Optimized four-component binder demonstrated the best performance in aggressive environments, especially in the simulated bottom water layer of the Shatt al-Arab.
  • Significant reduction in free calcium hydroxide content improved physico-mechanical properties and service performance.
