Abstract：In the rapid development of modern urban and rural construction,the recycling of construction waste has become a key problem to be addressed in the engineering field.This study aims to analyze the influence of the synergistic effect of coarse aggregate replacement gradients(0％-100％)and 0.2％glass fiber on the mechanical properties of recycled concrete.The results show that the compressive strength of all recycled concrete specimens is lower than that of the natural aggregate reference group;however,when the coarse aggregate replacement rate reaches 60％with the incorporation of 0.2％glass fiber,although the mechanical properties are not significantly enhanced,the comprehensive performance-such as internal structure and some performance indexes-is optimal.This provides an important reference for the rational application of recycled concrete in practical engineering.
