Overview

This study demonstrates how corrosion scenarios affect compressive strength in fiber-reinforced concrete, highlighting important microstructural changes.

Key Points

  • A polypropylene fiber content of 0.3 wt% enhances compressive strength and reduces deformation.
  • Higher corrosion concentrations decrease the elastic modulus, but fiber networks help maintain stiffness.
  • Severe corrosion increases microcrack density and accelerates critical strain zone formation.
  • SO₄²-/Cl- corrosion degrades C-S-H gel, creating gypsum and ettringite, influencing structural integrity.
