摘要

A large amount of old mortar is attached to the surface of recycled aggregate, which has a significant deterioration effect on the mechanical and fracture properties of recycled concrete, leading to a decrease in peak load and an increase in brittleness of recycled aggregate concrete. Adding steel fibers to recycled aggregate concrete can effectively improve its own strength, reduce the formation and development of microcracks, and improve toughness.
