This invention discloses a recycled mortar concrete, its preparation method, and its application, belonging to the technical field of recycled mortar concrete. The method involves modifying activated hydrophobic aerogel powder with 3-(methacryloyloxy)propyltrimethoxysilane, then incorporating the resulting modified aerogel powder containing double bond segments into a gel system for crosslinking. Water is added for dilution, resulting in a modified liquid with a solid content of 3-4%. Recycled aggregate is impregnated with the modified liquid to obtain modified recycled aggregate. The modified recycled aggregate, silicate cement, fly ash, quartz sand, water-reducing agent, and water are mixed to obtain recycled mortar concrete. The modified recycled aggregate in the recycled mortar concrete exhibits a crosslinked network on its surface, which acts as a thickener and retarder, regulating the fluidity of the concrete. Furthermore, the hydrophobic modified aerogel powder and crosslinked network seal and strengthen the pores of the recycled aggregate, blocking moisture and improving the freeze-thaw resistance and compressive strength of the recycled mortar concrete.
