摘要: Corrosion of steel reinforcement is the main cause deterioration in reinforced concrete structures. It can result cracking and spalling cover. After damaged cover repaired, corrosion might continue even accelerate. While development cell difficult to control, damage be possibly delayed controlled by use a suitable repair material. The lattice fracture model used this paper investigate performance strain hardening cementitious composite (SHCC) systems exposed ongoing corrosion. Numerical results were verified experimental tests when SHCC, nonreinforced material (repair mortar), commercial mortar are as materials. In experiments, bars (surrounded material) accelerated tests. influence substrate surface preparation, type material, interface, strength on resulting failure mode discussed. general, SHCC enables distributed with small crack widths, up several times smaller compared mortar. Furthermore, more warning signs prior final present system.
